Quien fue el primero en decir que el nimesulide (aulin)
mataba niños ¿
Quien publico las doce moléculas del patíbulo ¿
Quien fue el primero en decir que la isotretinoina
provocaba inducción al suicidio ¿

FUE EL DERMAGIC/EXPRESS, ESTA PAGINA QUE ESTAS LEYENDO EN
ESTOS MOMENTOS OK ¡!!!
Asi como les he dicho miles de verdades sobre las
farmacéuticas y sus danzas millonarias una vez mas les digo a todos NO SE
VACUNEN CONTRA LA H1N1, TODO ES UN ENGAÑO.
QUIERES 7 RAZONES PARA NO VACUNARTE ¿???? PORQUE lo que
desean es:
1.Primeramente VENDER UNA MILLONADA en vacunas que no
sirven para nada.
2. Crear una generación de niños AUTISTAS y población
enferma, la supervivencia del mas rico y poderoso, enfermarte, para que gastes
dinero en sus medicinas, seguros y hospitales.
3.Disminuir la población mundial, pues la superpoblación a
ocasionado crisis energética, eléctrica y de suministros básicos como el agua la
luz y alimentos.
4. Imponer una nueva clase de dominación mundial basada en,
el dominio de una superclase sobre otra disminuida y enferma, ejemplo de ello
Desiree Jennings.
5. Matar a la humanidad sin importarles nada, “hay que
disminuir el numero de habitantes” esa es la clave…sea como sea.
6.Hacer de todo esto una gran conspiración cuya conexión
principal es la OMS (organización mundial de la salud, y la farmacéutica
Baxter, la misma que contamino 72 kgs de material para fabricar vacunas y
naturalmente el gobierno de USA.
7. Si quieres proteger tu vida, cuando hagan el llamado a
vacunarte simplemente di que estas enfermo del corazón, que eres cardiópata, que
sufres de los pulmones, que tienes toxoplasmosis,que sufres de artritis
reumatoide, o simplemente que tomas medicación para los nervios. Si no tienes el
soporte consíguelo con un medico amigo. Y si no lo consigues simplemente…….
DILES QUE NO, NADIE PUEDE OBLIGARTE A COLOCARTE UNA VACUNA
QUE PUEDE CONVERTIRTE EN UN ZOMBIE como a Desriree Jennings. O lo peor convertir
a tu hijo en AUTISTA,, Y MATARTE A TI o enfermarte irreversiblemente con daños
irrecuperables.
Recuerda lo que siempre he dicho en el DERMAGIC, nunca me
he equivocado, y esta vez tampoco lo hare. Recuerdalo siempre donde quiera que
estes y me estes leyendo.

EVIL II, SEVEN REASONS FOR NOT VACCINATING !!! Who was, the person that said for
the first time that he came closer a bacteriological or virologic war ?
Who the person that I publish in the year 2.002 (7 years ago) the adverse
effects of the timerosal, the autism and the harmful effect of the adjuvants of
the vaccines ? Who was the first one in saying that the nimesulide (aulin) it
killed children ? Who publish the dirty dozen molecules ?
Who was the first one in saying that the isotretinoin caused induction to the
suicide ? Who it was and it is the one that has said in but of 3 occasions
that the leprosy doesn't have vaccine. that is a pure lie ?
Who said for the first time that the desloratadine caused convulsions in
children?
IT WAS THE DERMAGIC/EXPRESS, THIS WEB, THAT YOU ARE READING IN THESE MOMENTS
OK!!! As well as I have told you thousands of truths on the pharmaceuticals
and their millionaire dances, once but I tell to all OF YOU THAT not VACCINATED
AGAINST THE H1N1, EVERYTHING is A LIE, FALSE, NOT TRUE.
Do you WANT 7 REASONS FOR NOT VACCINATING ???? BECAUSE what they want is:
1.First, to SELL A MILLIONS in vaccines that are not good for any
people. 2. To create a generation of AUTISTIC children and sick population,
the survival of the but rich and powerful, to get sickness to you, so that you
spend money in their medicines, and hospitals.
3.To diminish the world population, because the overpopulation had caused
energy, electric crisis and of basic supplies as the water the light and foods.
4. To impose a new class of world dominance based in, the domain of a
superclas on another diminished and sick, example of it, Desiree Jennings.
5. To kill the humanity without caring them anything, "it is necessary to
diminish the I number of inhabitants" that it is the keyword…it doesn't care the
costs.
6. To make of all this a great conspiracy whose main connection is the
OMS (world organization of the health, and the pharmaceutical Baxter, the same
one that I contaminate 72 material kgs to manufacture flu vaccins, and naturally
the government of USA.
7. if you want to protect your life, when they make the call to vaccinate you
simply tell them that you are sick person of the heart, that you suffer of
the lungs that you have toxoplasmosis, or suffers of reumatoid arthritis, or
simply that you take medication for the nerves. If you don't have the support
you get it with a dr friend. And if you don't simply get it…….
YOU TELL THEM NOT, NOBODY can PUT ON YOU, in your body AN OBLIGATION to PLACE
YOU A VACCINATION... THAT It can BECOME YOU A ZOMBIE like to Desriree
Jennings. Or the worst thing, to convert your son in AUTISTIC, AND to KILL YOU
or to get sick irreversibly with unrecoverable damages.
Remembers what I have said always in the DERMAGIC, I have never made a
mistake, and this time neither I will make it. Always remember it will be there
where ever you are reading me.
This publication is a tribute to DESIREE JENNINGS AND ALL THOSE THAT have
ALREADY MANIFESTED THE VACINE ADVERSE EFFECTS OF THOSE DIABOLICAL ones.
Don't become a new RESIDENT EVIL !!!! ... DON'T ALLOW IT

A scandal dating from January 2008, that is continuing to unfold, raises more
disturbing questions over the safety of U.S. pharmaceutical company Baxter
International’s vaccines.
Last year Baxter recalled almost all of its injections of the blood thinning
heparin drug in the US after some patients experienced extreme - and in some
cases fatal - allergic reactions, after being administered the products.
There were similar recalls by other manufacturers of Chinese-sourced heparin in
Denmark, Italy, France Germany and Japan, but initial investigations found that
only Baxter’s heparin vaccines were tainted.
Then, in January 2009 a new lawsuit was filed specifically against Baxter for
it’s role in the scandal.
The allegation is that the pharmaceutical giant purposefully altered an
ingredient in heparin that flowed through heparin syringes to patients,
resulting in pain and suffering, and sometimes death, to those affected,
reported legal website Lawyers and Settlements
Somewhat ironically, the natural ingredient in heparin that was substituted in
order to cut costs was a substance extracted from cooked swine intestines.
Baxter has been chosen by the WHO to head up efforts to produce a vaccine for
the Mexican swine flu that is spreading throughout the U.S. and Europe.
The decision was made despite further revelations last month that vaccines
contaminated with deadly live H5N1 avian flu virus were recently distributed to
18 countries by a lab at an Austrian branch of Baxter.
Initially, the company attempted to stonewall questions by invoking “trade
secrets” and refused to reveal how the vaccines were contaminated with H5N1.
After increased pressure they then claimed that pure H5N1 batches were sent by
accident.
However, the probability of mixing a live virus biological weapon with vaccine
material by accident is virtually impossible.

Description
FIELD OF THE INVENTION
[0001]The present invention relates to methods for producing viral vaccines.
DESCRIPTION OF THE RELATED ART
[0002]A vaccine is an immunogenic composition of an antigenic substance, e.g.
the (non-infectious) pathogen such as a virus, its envelope, particles or its
protein antigens. Administration or vaccination results in the immunization in a
subject, e.g. a mammal such as a human, or a bird. The vaccination might cause a
specific reaction to the vaccine and some minor inflammation, but this is
generally much less detrimental than an infection of a fully viable virus which
the vaccine is designed to prevent. The immune system of the subjects will adapt
itself to specifically recognize the antigens of the vaccine and swiftly
inactivate the pathogen after further exposure of the subject to the pathogen.
Thus an increased resistance against the pathogen is achieved through
vaccination.
[0003]For vaccine purposes a virus is conventionally cultivated on an adequate
cell culture or generally cellular substrate. In the case of influenza, normally
embryonated chicken eggs are used. The infectious viral harvest is collected and
purified to remove unwanted non-viral cell constituents. In particular, in the
case of vaccines derived from chicken substrates allergic reaction to
chicken/egg proteins are possible in certain susceptible individuals.
[0004]An essential step in the production of viral vaccines is the inactivation
of the infectious viruses. Formalin (an aqueous solution of formaldehyde) is the
most frequently used inactivating agent in the manufacture of vaccines. It is
usually used as a saturated aqueous solution with concentration of around 37%
formaldehyde. Formaldehyde inactivates a virus by irreversibly cross-linking
primary amine groups in surface proteins with other nearby nitrogen atoms in
protein or DNA through a --CH.sub.2-linkage. In particular these cross linkages
could lead to bonds with non-viral substances and it is therefore necessary to
perform some previous purification on the live infectious virus, since
inactivation prior to purification would give rise to a large amount of
irreversible chemical bridging between viral proteins and impurities, which are
detrimental to the efficacy of the purification operations and product quality.
For this reason, live infectious viruses are first at least partially purified
in the prior art, e.g. by zonal ultracentrifugation, and then inactivated (U.S.
Pat. No. 6,048,537). The formalin inactivation step has been validated with
established analytical procedures.
[0005]Complementing formalin treatment, UV inactivation has been considered for
integration into the manufacturing process. The use of ultraviolet
irradiation-inactivation for human vaccines has been demonstrated before for
unenveloped and enveloped virus (US 2006/0270017). As the viral genome is more
susceptible to UV-damage than viral surface antigens, UV-inactivation was shown
to have little negative effect on the biochemical characteristics or
immunogenicity of the product. The targets for UV inactivation are primarily
nucleic acids in contrast to proteins which are targeted by formalin.
[0006]By combining formalin and UV-inactivation, scientists tried to overcome
the limitations of isolated UV-inactivation or formalin-inactivation,
respectively, when inactivating particularly resilient virus families.
[0007]Alternatively, many manufacturers use a detergent-based process step to
both inactivate the live virus and to modify the virus. These detergent-based
processes disrupt the lipid envelope of influenza viruses to yield either split
(partially disrupted) or sub-unit (fully disrupted) vaccine antigen. Detergent
treatment often reduces the reactivity of the virus antigen, and thus reduces
unwanted side effects during vaccination. The detergent treated virus may be
further inactivated by, e.g., formalin treatment. Examples of these methods may
be found in U.S. Pat. No. 6,048,573, U.S. Pat. No. 4,522,809, and WO 02/09702. A
disadvantage in this approach is that the virus undergoes various purification
steps prior to the disruption step, and thus live infectious virus is handled by
manufacturing personnel at several stages. This is of especial concern when
vaccine against especially virulent forms of influenza, such as H5N1 strains, is
being produced.
SUMMARY OF THE INVENTION
[0008]It is an object of the present invention to provide a method of producing
viral vaccines with a reduced number of steps requiring the handling of
infectious material, while producing viral antigens of decreased reactivity.
[0009]Therefore the present invention provides a method for the manufacture of a
preparation comprising virus antigens comprising
[0010]a) inoculation of cells with infectious virus in a fluid,
[0011]b) propagation of said virus in said cells,
[0012]c) collecting said propagated virus in the cell culture supernatant,
[0013]d) inactivating said collected virus, and
[0014]e) treating said inactivated virus with a detergent, resulting in a
preparation comprising viral antigens.
[0015]In a second aspect a method for the manufacture of a preparation is
provided comprising viral antigens comprising
[0016]a) obtaining a fluid comprising infectious virus,
[0017]b) completely inactivating said collected virus,
[0018]c) treating said inactivated virus with a detergent, and
[0019]d) purifying said inactivated virus resulting in a preparation comprising
viral antigens.
[0020]Other aspects of the invention provide vaccine preparations prepared from
the viral antigens produced according to the methods of the invention.
[0021]In another aspect the present invention provides the method of increasing
the resistance to a viral infection in a subject comprising manufacturing a
preparation comprising viral antigens and administering said preparation to a
subject.
BRIEF DESCRIPTION OF THE DRAWINGS
[0022]FIG. 1a shows a flow chart of the inventive procedure from virus
collection after propagation to the inactivated harvest.
[0023]FIG. 1b shows a continuation of the flow chard of the inventive procedure
from inactivated harvest to a monvalent bulk preparation.
DETAILED DESCRIPTION OF THE INVENTION
[0024]Provided is a method for the manufacture of a preparation comprising virus
antigens comprising
[0025]a) inoculation of cells with infectious virus in a fluid,
[0026]b) propagation of said virus in said cells,
[0027]c) collecting said propagated virus in the cell culture supernatant,
[0028]d) completely inactivating said collected virus, and
[0029]e) treating said inactivated virus with a detergent, resulting in a
preparation comprising viral antigens. Central to this procedure is that it is
possible to reduce the number of steps performed on an active virus and thus the
virus is inactivated after collection of the primary harvest prior to the
detergent treatment and/or optional purification steps.
[0030]The "virus antigen" according to the present invention is a virus or
portion of the virus which can induce an immune response in a subject against
said antigen. Absolute success in the sense of completely immunising the subject
is not required but this is to be understood in the sense of increasing the
immune defence or immune response against said virus which reduces the chance of
developing a disease associated with said virus after further exposure. Such a
virus antigen can, e.g., be a whole inactivated virus, a split virus, a modified
virus, viral proteins, in particular surface proteins, like haemagglutinin or
neuraminidase. A "vaccine" is a preparation of said virus antigen in a form for
administration, such as for injection, nasal, or transdermal administration.
"Purification" according to the present invention relates to steps of removing
non-viral constituents of the harvest fluid. The harvest fluid obtainable after
the collection step is preferably a clarified supernatant, wherein solid or
large impurities, e.g. remaining intact cells or cell debris of infected cells
which break up during virus propagation, are removed by precipitation, e.g. via
centrifugation. Therefore "collecting" refers to any steps that yield whole
infectious viruses in a fluid, in particular clear fluid. Apart from removing
cell debris the collection step can also include steps to remove other solid
constituents of the cell growth medium or substrate e.g. any kind of substrate
on which the cells are cultured. Propagated whole virus is released into said
cell culture supernatant from which it can be collected. Therefore in a
particular embodiment of the invention the step of collecting the propagated
virus comprises separating the virus from the cells and/or cell debris of said
cells after infection. This separation can, e.g., be facilitated by a low speed
centrifugation of about 2000 g to 3000 g, up to 5000 g, 10000 g, 15000 g or
20000 g, which separates visible particles from the fluid. Alternately, the
separation may be carried out by filtration. In particular preferred embodiments
said fluid is substantially free of allantoin, collagen and/or albumin, such as
ovalbumin, e.g. by choice of the cells used for virus propagation, e.g.
mammalian, avian or insect cell cultures instead of embryonal eggs. In
particular embodiments of the invention, African green monkey kidney (VERO)
cells are used for viral propagation.
[0031]After the collecting step the virus is inactivated by any known means for
virus inactivation, e.g. as disclosed in the US publication number 2006/0270017
A1, which is incorporated herein by reference. In particular, inactivation can
be performed by formaldehyde treatment and/or UV irradiation, alone or in
combination. As used in this application, "complete inactivation" or "completely
inactivated," as they refer to a viral preparation, means that the viral
preparation does not contain plaque forming units (pfu,) as determined by
culture of the viral preparation on chicken embryonic fibroblasts (CEF) or VERO
cells.
[0032]One of the beneficial effects of the inventive methods is the reduction of
steps which are performed on infectious viral media for which specific safety
precautions are required. In the state of the art it was considered to be
necessary to perform a purification step on the primary harvest to remove or
substantially reduce non-viral proteins or nucleic acids which could cross-link
with the virus during formalin treatment. This prejudice was overcome with the
present invention which showed that it is indeed possible or even advantageous
to inactivate directly after collection of the virus prior to the purification.
To avoid such adverse reaction during inactivation the virus containing fluid,
or its non-viral constituents, is (are) preferably not further concentrated or
concentrated by a factor of below 10, 9, 8, 7, 6, 5, 4, 3 or 2 during or after
the collection step. Preferably the concentration of non-viral protein and/or
DNA of the native supernatant from the cell culture is maintained prior to the
inactivation step. In particular embodiments the whole protein or non-viral
protein concentration is in the range of .mu.g/ml, such as below 950 .mu.g/ml,
900 .mu.g/ml, 850 .mu.g/ml, 800 .mu.g/ml, 700 .mu.g/ml, 650 .mu.g/ml, 600
.mu.g/ml, 550 .mu.g/ml, 500 .mu.g/ml, 450 .mu.g/ml, 400 .mu.g/ml, 350 .mu.g/ml,
300 .mu.g/ml, 250 .mu.g/ml, 200 .mu.g/ml, 150 .mu.g/ml, 100 .mu.g/ml, 80
.mu.g/ml, 60 .mu.g/ml, 40 .mu.g/ml, 30 .mu.g/ml, 20 .mu.g/ml, 10 .mu.g/ml, 8
.mu.g/ml, 6 .mu.g/ml, 4 .mu.g/ml, 3 .mu.g/ml, 2 .mu.g/ml or below 1 .mu.g/ml, in
the fluid during inactivation or after collecting the virus.
[0033]For the inactivation any amount of formaldehyde or UV irradiation dosage
can be selected which are effective to inactivate the virus, alone or in
combination. In a preferred embodiment of the present application the virus
titer reduction due to the inactivation of the virus in the sample is at least
about 1.times.10.sup.5, in a more preferred embodiment, at least about
1.times.10.sup.7 in a more preferred embodiment at least about
1.times.10.sup.10, and in a most preferred embodiment at least about
1.times.10.sup.14.
[0034]In a preferred embodiment of the present invention, the sample is treated with an effective concentration of formalin for about 12 to about 96 hours. In
more preferred embodiments, the sample is treated with an effective
concentration of formalin for about 24 to about 48 hours, and more preferably
for about 24 to about 30 hours. In an especially preferred embodiment of the
present invention, the sample is treated with an effective concentration of
formalin for about 24 to about 24.5 hours. Those of skill in the vaccine arts
will recognize that formalin concentration and treatment times may need to be
optimised for the particular strain of virus treated in order to effect complete
inactivation, wither alone or in combination with UV light. In a further
embodiment the step of treating the sample with an effective concentration of
formalin is carried out at about 10 to about 40.degree. C. In an especially
preferred embodiment of the pre-sent application the step of treating the sample
with an effective concentration of formalin is carried out at about 32.degree.
C.
[0035]A preferred embodiment of the present invention includes the treatment of
the sample with an effective concentration of formalin, wherein the effective
concentration of formalin ranges preferably from about 0.01% to about 1% (w/w),
preferably from about 0.01% to about 0.1% more preferably between about 0.025%
and about 0.1% which corresponds to about 92 mg/l and about 368 mg/l formalin
respectively when using a 37% formalin solution for adjusting the effective
concentration.
[0036]In the present application the term "UV light" means ultraviolet radiation
having a wavelength of 100 to 400 nm. The UV light may be selected from the
group consisting of UV C (100 to 280 nm), UV B (280 to 320 nm), and UV A (320 to
400 nm). Photosensitizing agents like those which intercalate into the DNA and
are activated by UV light, e.g. psoralens, may be used to enhance the
inactivating effect of the UV radiation. In a preferred embodiment of the
present invention the UV light is UV C having a wavelength of about 100 to about
280 nm. In a more preferred embodiment of the present invention the UV light has
a wavelength from about 240 to about 290 nm. In an especially preferred
embodiment of the present invention about 85% or more of the UV light have a
wavelength of about 254 nm.
[0037]The UV light emission may be a continuous form of UV light emission, e.g.
mercury lamp technology, or pulsed UV light, e.g. monochromatic laser
technology. The desired UV intensity may be generated by combining two or more
lamps. The subject matter of the invention encompasses any effective dose of UV
light, i.e. any dose of UV light which safely inactivates a given virus
preferably when combined with a formalin treatment. Those of skill in the
vaccine arts will recognize that UV light wavelength and exposure may need to be
optimised for the particular strain of virus treated in order to effect complete
inactivation, either alone or in combination with formalin treatment. The
effective dose may depend on a variety of factors which are generally known in
the field, e.g. the physical parameters of the UV inactivation chambers such as
size and diameter of the lamp and the chamber, distance between the virus
containing medium and the UV light source, light absorption and reflection
properties of the material of the chamber. By the same token, the wavelength and
intensity of the UV C light as well as the contact time the virus is exposed to
the UV light is also critical for the effective dose. Furthermore, the effective
dose is also influenced by the virus itself, the medium containing the virus and
their light absorption properties. Preferably, the effective dose is sufficient
for inactivating at least 99.99% of virus contained in the sample, more
preferably inactivating the virus to a level where no active virus is detected
in a mammalian or avian cell culture test, or completely inactivated. In a
preferred embodiment using UV C light a sample containing the virus is exposed
to an effective dose ranging from about 5 to about 200 mJ/cm.sup.2. In a
preferred embodiment the effective dose is in the range of about 20 to about 100
mJ/cm.sup.2, and in other preferred embodiments the effective dose in the range
of about 40 to about 90 mJ/cm.sup.2. In a preferred embodiment, the effective
dose reduces an initial virus titer by 1.times.10.sup.5. In bulk vaccine
inactivation, the effective dose should be sufficient to eliminate any residual
live virus which may be present after the chemical (formalin) inactivation step.
As illustrated in the examples, this may be determined by very sensitive
mammalian cell culture infection tests, such as the Vero cell culture test
described in Example 1.3.
[0038]After inactivation the virus antigens are purified. The purification is
preferably performed by ultracentrifugation at e.g. in the range of about 100000
g such at least 50000 g, 60000 g, 70000 g, 80000 g, or 90000 g, or up to 200000
g, 180000 g, 160000 g, 140000, g 120000 g or 110000 g. The ultracentrifugation
method is commonly known in the art and is used in the routine manufacture of
viral vaccines as e.g. described in the U.S. Pat. No. 6,048,537, which is thus
incorporated by reference. Preferably the ultracentrifugation is performed in a
sucrose density gradient which establishes itself during the centrifugation. In
particular preferred embodiments the sucrose gradient is formed by using a
solution of about 42% to 55% (w/w-%) sucrose (or any other adequate carbohydrate
or sugar known in the art). For ultracentrifugation a continuous flow centrifuge
may be used. The parameters for fractionating after ultracentrifugation are
dependent on the characteristics of the virus strains used. The parameters for
collection of the peak pool fractions are evaluated and determined individually
for each virus strain and are in the range of about 46-50% to 34-38% sucrose.
Preferably non-viral material (e.g. at this stage whole inactivated virus) are
removed by density separation. Cell membrane fragments, including liposomes and
proteins each have a characteristic specific density. Viruses as being a
characteristic composition of proteins, nucleic acids and in the case of
enveloped viruses also membrane can be purified by their specific density from
non-viral material. In particular the whole viral antigens may be purified from
incomplete virus portions, or vice versa.
[0039]This step of purifying the inactivated virus comprises at least partially
removing soluble non-viral material from the virus. In particular the soluble
non-viral material comprises cell proteins or cell nucleic acids from the cell
of the original cell medium or culture. Non-viral material, including incomplete
virus portions, is preferably reduced by an amount of at least 20%, preferably
at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85% or at
least 90% during purification.
[0040]In particular preferred embodiments the collected fluid is treated with a
nuclease to degrade nucleic acids of the host cells. Such a nuclease can be e.g.
benzonase.
[0041]In a further embodiment of the present invention, the cells use for cell
culture and viral propagation may be primary cells or any cultured cell line
suitable for producing the virus. Examples of cells which may be used include
mammalian cells (e.g., CHO, BHK, VERO, HELA, or perC6 cells), avian cells (e.g,
chicken embryo fibroblasts, or continuous cell lines from an avian) and insect
cells (e.g, Sf9 cells.). In particular preferred embodiments the cells are in
form of a cell culture. The inventive method allows effective purification,
including splitting of the material despite of the potential cross linking
properties of the previous inactivation reagents. In contrast to egg grown
virus, cell culture derived virus is of higher initial purity and is free of
albumin and collagens, which represents an important advantage for the
purification of the formalin treated harvest. The innovative formulation of the
resulting product is free of flocculation without any need for stabilizers such
as tocopherol or laureth-9.
[0042]In the present invention, the viruses to be inactivated are selected from
enveloped DNA or RNA viruses, with single or double (DNA) stranded genomes,
sense or antisense, continuous or segmented. In preferred embodiments of the
invention, the viruses are selected from the group of enveloped viruses,
including, flaviviruses, togaviruses, retroviruses, coronaviruses, filoviruses,
rhabdoviruses, bunyaviruses, orthomyxoviruses, paramyxoviruses, arenaviruses,
hepadnaviruses, herpesviruses, and poxviruses. In other preferred embodiments,
the viruses are flaviruses, coronaviruses, orthomyxoviruses, or togaviruses.
Particularly preferred are enveloped viruses such as influenza, including
strains of influenza A, B or C, West Nile, and Ross River viruses (RRV.) In
other preferred embodiments of the invention, the viruses are selected from the
group of enveloped RNA viruses, including, flaviviruses, togaviruses,
retroviruses, coronaviruses, filoviruses, rhabdoviruses, bunyaviruses,
orthomyxoviruses, paramyxoviruses, and arenaviruses. In one particularly
preferred embodiment, the virus is selected from the orthomyxoviruses, for
example, an influenza virus strain: influenza virus strains may have varying
combinations of hemaglutianin and neuraminidase surface proteins. In another
particularly preferred example, the virus is selected from the togaviruses, for
example an alphavirus such as the RRV) Another preferred group of viruses for
use as the bulk viral solution are the coronaviruses, including the virus
associated with Severe Acute Respiratory Syndrome (SARS). Another group of
preferred viruses are the flaviviruses, including Japanese Encephalitis, tick
borne encephalitis (TBE), Dengue fever virus, yellow fevers virus, West Nile
Virus and hemorrhagic fever virus. Another preferred group of viruses are the
poxviruses, including orthopox-viruses (such as vaccinia or modified vaccinia
Ankara viruses), and avipoxviruses.
[0043]In further embodiments the purified virus is further processed. After
purification further steps can comprise dilution of the purified virus, in
particular after sucrose ultracentrifugation in order to dilute the viscous peak
pool fraction which is expected to contain about 40% sucrose. The purified virus
can be homogenized, additionally nuclease treated, pressure and/or
ultra/diafiltrated.
[0044]In embodiments of the invention, the virus is modified by detergent
treatment to produce a modified whole virus or split virus vaccine. The
modification of the lipid envelope of the virus is carried out by solubilisation
with a detergent such as Triton X100 in a concentration suitable to destabilize
or disintegrate the virus, in particular the viral lipid envelope membrane. The
detergent treatment will at least in part remove the membrane of said virus.
Preferably the detergent concentration is removed, e.g. by diafiltration or
chromatographic processes. Detergents for use in the detergent treatment step
include ionic (cationic, anionic, zwitterionic) detergents or non-ionic
detergents. Suitable detergents include the Tween group of detergents (e.g.,
Tween 80), and the Triton group of detergents (e.g., Triton 100.)
[0045]Optionally, the viral antigen preparation is further stabilized by an
additional formaldehyde treatment or stabilizer addition such as by usage of
detergents as disclosed in the WO 02/097072 A2 which is incorporated herein by
reference. Such detergents are for example detergents suitable to stabilize the
HA protein, such as Tween 80, Triton X100, deoxycholate, laureth-9 and
tocopherol. It is thought that surface proteins are kept solubilized by complex
micelles of membrane constituents and the detergents.
[0046]In particular preferred embodiments the virus is further processed to a
split virus comprising any one of the following steps of dilution,
homogenisation, nuclease treatment, pressure filtration, ultra/diafiltration,
solubilisation, diafiltration, stabilization by formaldehyde treatment,
dilution, ultra/diafiltration, (detergent) stabilizer addition, a second
homogenisation and sterile filtration.
[0047]In other particular preferred embodiments the virus is further processed
to a modified virus preparation comprising any one of the following steps of
dilution, homogenisation, nuclease treatment, pressure filtration, detergent
treatment, ultra/diafiltration, stabilizer addition, a second homogenisation and
sterile filtration. In particular the detergent stabilization is performed to
introduce a detergent into the viral membrane in the case of enveloped virus to
increase the stability of the complete virus, which is thus modified.
[0048]In additional embodiments the virus is processed to a sub-unit vaccine
comprising the isolation of single viral subunits or viral proteins, in
particular surface proteins like heamaggutinin or neuraminidase. The isolation
can e.g. be performed by affinity purification and/or chromatographic methods
such as ion exchange chromatography.
[0049]Surprisingly the method of the present invention is suitable for
industrial scale production of virus antigen vaccines. Therefore preferably the
inactivation or any other step such as the inoculation, the propagation the
collection or the purification is performed on amounts or yields amounts of at
least 0.51, 11, 21, 31, 41, 51 61, 71, 81, 91, 101, 121, 141, 161, 181, 201,
251, 301, 351, 401, 601, 801, 1001, 1201, 1401, 1601, 1801, 2001 of a fluid
comprising a virus or viral antigen.
[0050]In a further aspect the present invention also provides a method for the
manufacture of a preparation comprising viral antigens comprising
[0051]a) obtaining a fluid comprising infectious virus,
[0052]b) completely inactivating said collected virus,
[0053]c) treating said inactivated virus with a detergent,
[0054]d) purifying said inactivated virus resulting in a preparation comprising
viral antigens. Of course it is also possible to use infectious virus containing
fluids per se, which can be from any cell supernatant as described above, for
inactivation, detergent treatment, and purification. Preferably said fluid
comprising infectious virus is obtained from a cell culture.
[0055]In particular preferred embodiments the virus antigens, in particular
split virus or modified virus antigens, are stabilized by addition of an
effective amount of Tween 80, in particular preferred at a concentration of
about 0.125%, e.g. above 0.01%, 0.05% or 0.4%, and below 0.6%, 0.5%, 0.4%, 0.3%,
or 0.2%. Therefore the present invention also provides in a further aspect the
method of stabilizing viral antigens by addition of Tween 80. According to the
present invention it was found that as a detergent Tween 80 is less potent to
solubilize viral membranes as Triton X100 but is by far more biocompatible and
can be present in a vaccine preparation. The effective amount to stabilize viral
antigens is preferably below the amount to solubilize viral membranes as in the
split virus solubilization procedure using high concentrations of Triton X100 of
e.g. 0.5%. In other embodiments the viral antigens are free of stabilizers. In
particular embodiments a production of a split vaccine is provided by a process
where the virus harvest is fully inactivated prior to the splitting and
purification process. Surprisingly, the inactivation process with formalin
treatment and UV treatment does not interfere with the subsequent detergent
treatment and purification processes.
[0056]In further embodiments a vaccine or pharmaceutical composition is provided
which comprises one or more viral antigens. Such a pharmaceutical composition
can further comprise a pharmaceutical carrier and/or an adjuvant. Such
pharmaceutical carriers are for example stabilising salts, emulgators,
solubilisers or osmo-regulators, suspending agents, thickening agents, redox
components maintaining a physiological redox potential. Pre-ferred adjuvants
include aluminium salts, microemulsions, lipid particles, and/or
oligonucleotides used to increase the immune response. A further aspect of the
present invention is a pharmaceutical composition or preparation as vaccine
comprising an antigen. A vaccine can be used e.g. for an injection as a
prophylactic means against a virus associated disease. In particular preferred
embodiments the composition or vaccine comprises more than one antigen, e.g. 2,
3, 4, 5, 6, 7 or 8, in particular of different virus strains, subtypes or types
such as influenza A and influenza B, in particular selected from of one or more
of the human H1N1, H2N2, H3N2, H5N1, H7N7, H1N2, H9N2, H7N2, H7N3, H10N7
subtypes, of the pig flu H1N1, H1N2, H3N1 and H3N2 subtypes, of the dog or horse
flu H7N7, H3N8 subtypes or of the avian H5N1, H7N2, H1N7, H7N3, H13N6, H5N9,
H11N6, H3N8, H9N2, H5N2, H4N8, H10N7, H2N2, H8N4, H14N5, H6N5, H12N5 subtypes.
[0057]Suitable adjuvants can be selected from mineral gels, aluminium hydroxide,
surface active substances, lysolecithin, pluronic polyols, polyanions or oil
emulsions such as water in oil or oil in water, or a combination thereof. Of
course the selection of the adjuvant depends on the intended use. E.g. toxicity
may depend on the destined subject organism and can vary from no toxicity to
high toxicity.
[0058]Another preferred embodiment of the composition or vaccine of the present
invention further comprises buffer substances. Buffer substances can be selected
by the skilled artisan to establish physiological condition in a solution of the
composition according to the invention. Properties like pH and ionic strength as
well as ion content can be selected as desired.
[0059]A further preferred composition or vaccine according to the invention,
comprises a pharmaceutically acceptable carrier.
[0060]The term "carrier" refers to a diluent, e.g. water, saline, excipient, or
vehicle with which the composition can be administered. For a solid composition
the carriers in the pharmaceutical composition may comprise a binder, such as
microcrystalline cellulose, polyvinylpyrrolidone (polyvidone or povidone), gum
tragacanth, gelatine, starch, lactose or lactose monohydrate; a disintegrating
agent, such as alginic acid, maize starch and the like; a lubricant or
surfactant, such as magnesium stearate, or sodium lauryl sulphate; a glidant,
such as colloidal silicon dioxide; a sweetening agent, such as sucrose or
saccharin.
[0061]Also provided is the method of increasing the resistance to a viral
infection in a subject comprising manufacturing a preparation comprising one or
more different viral antigens and administering said a preparation comprising
one or more viral antigens as described above to a subject. The preparation is
preferably a vaccine. It is also contemplated to provide the virus antigens as
prepared by the present invention as a vaccine or for increasing the resistance
to a viral infection in a subject by administering said virus antigens.
EXAMPLES
Example 1
Inactivation of Infectious Virus
[0062]Three different influenza strains, two A-strains Hiroshima (HR, H3N2), a
New Calcdonia (NC, H1N1) and a B-strain, Malaysia (MA), were produced in Vero
cell cultures. After virus propagation the infectious virus harvest is
inactivated prior to purification as given in the flow chart of FIG. 1a.
[0063]1.1. Formalin Inactivation
[0064]The first inactivation step with formalin is carried out on a cell-free,
infectious monovalent virus harvest, i.e. a bioreactor harvest after
clarification via centrifugation. After the collection at 30 to 34.degree. C.,
the monovalent virus harvest is treated with about 0.9 to about 1.1 U/ml
Benzonase at 30 to 34.degree. C. for 4 to 8 hours. Then it is treated with <=92
mg/l formalin for 24 to 24.5 hours at 32+/-2.degree. C.
[0065]1.2. UV Inactivation
[0066]A number of inactivation experiments with formalin-inactivated viruses are
carried out using an inactivation chamber with a 65 W UV lamp and a thin layer
chamber. Although full inactivation of monovalent virus harvest can be
demonstrated when using flow rates of 100 liter per hour for three cycles, this
setup did not allow the on-line measurement of the UV signal. The Vero cell
culture medium used for Influenza production contains various organic compounds
responsible for absorption of the UV signal. Therefore, the system, is equipped
with a 110 W lamp allowing a continuous monitoring of the UV signal during
monovalent virus harvest treatment.
[0067]Formalin treated monovalent Influenza Panama harvest is used as a model
substrate for the inactivation. For continuous inactivation with thin layer UV
technology a WEDECO VISA system (Germany) equipped with a VISA lamp (110 W) is
used. The UV thin layer chamber is a stainless steel 1.4435 device with a 30 mm
diameter quartz tube. A calibrated UV sensor allows on-line control of the UV
signal. The UV thin layer chamber is operated at a flow rate of 240+/-10 liter
per hour at ambient temperature. The flow rate conditions are controlled by a
calibrated flowmeter. The monovalent harvest is exposed to 10 UV cycles. After
each cycle 20 liter of the UV treated monovalent harvest is removed and further
purified by sucrose gradient purification using continuous ultracentrifugation.
[0068]1.3. Safety Test
[0069]The standard Vero safety test is a highly stringent quality test for the
residual infectivity of inactivated influenza strains. The test is also
applicable to other viruses. A monovalent bulk product, i.e. purified virus
antigen after sucrose gradient centrifugation and ultra-diafiltration, is added
to 5 Roux flasks (4 ml/flask). After incubating for 7 days at 32.degree. C. in
Vero culture medium, the cell cultures are harvested, pooled and added to 5 Roux
flasks (10 ml/flask). After another incubation step for 7 days at 32.degree. C.,
the cell cultures are harvested, pooled, and tested for hemagglutinin (HA).
[0070]The HA-test is based on the fact that Influenza viruses can bind
erythrocytes using their surface protein hemagglutinin. The test is carried out
in a sterile environment. A suspension of Influenza viruses with a defined HA
titer serves as a positive control and a 0.9% NaCl solution serves as a negative
control. 50 .mu.l of a 1:2 dilution in 0.9% NaCl of a sample to be tested are
given into one well of a 96-well plate. To each well 50 .mu.l of a solution
containing chicken erythrocytes is added. Subsequently, the plates are incubated
for 30 to 45 minutes at room temperature. Then the hemagglutination is visually
determined, wherein, if five wells containing the same sample do not show any
hemagglutination, the sample passed the HA test.
Example 2
Purification by Ultracentrifugation
[0071]During purification of influenza virus antigen, the monovalent harvest
(MVH) is concentrated by centrifugation. A continuous flow centrifugation
procedure can be applied for the manufacture of the Vero cell culture grown
viral vaccine based on a sucrose gradient formed using an aqueous sucrose
solution. The centrifuge model used was equipped with a preclarifier. Small
scale experiments with a density gradient formed using approx. 42% and 55% (w/w)
sucrose solution in 20 mM Tris-buffer were carried out under different
centrifugation conditions. In addition, ultracentrifugation without preclarifier
but with increased g-forces turned out to be a valuable tool for yield
improvement.
[0072]Monovalent Influenza virus harvests (MVHs) were used for the comparative
studies. The MVHs were purified with continuous ultracentrifugation with a
laboratory centrifuge model RK-6 at 35.000 rpm.
Example 3
Purification/Processing
[0073]For an influenza candidate vaccine, three different strains of influenza
were purified and collected from ultracentrifugation as described in example 2.
Antigen yields were different in the Peak Pools. The influenza strain New
Calcdonia had the lowest antigen yield followed by Hiroshima and finally
Malaysia. Protein content was highest in the Malaysia and lowest in the
Hiroshima. SRD (Single Radial Immunodiffusion Assay (HA-quantification)) to
Total Protein ratios were comparable in Peak Pools from Malaysia and New
Calcdonia, but higher in the Hiroshima (Table 1).

Further processing was according to the following overview:
[0074]3.1. Dilution of Peak Pools
[0075]The Peak Pools are diluted 3 fold with TBS buffer to reduce sucrose
concentration for reduction of viscosity.
[0076]3.2. First Homogenization Peak Pool
[0077]The diluted Peak Pool is treated with a high pressure homogenizer "NS
1001L Panda" (Niro Soavi S.p.A.). The virus suspension is passed through the
homogenizer 3 times with 800 bar. This pressure is sufficient to improve
subsequent processing steps by disrupting virus aggregates.
[0078]3.3. Benzonase Addition
[0079]Benzonase, a recombinant nuclease produced in E. coli, is added to the
virus suspension at a final concentration of 3 U/ml to degrade cell derived DNA.
[0080]3.4. Pressure Filtration
[0081]After Benzonase addition, a 0.22 .mu.m pressure filtration is performed to
keep the virus suspension free of advantitious organisms such as bacteria during
the subsequent incubation period. Incubation is performed at 32.degree. C. over
night.
[0082]3.5. Ultra/Diafiltration
[0083]After Benzonase incubation is finished, Ultra/Diafiltration is performed
with a 30 kD suspended channel ultrafiltration membrane (Pall) with a filtration
area of 0.1 m.sup.2 at small scale and 0,5 m2 at pilot scale. The Ultraretentate
is diafiltrated with 10 Retentate volumes of TBS (Tris buffered saline)+0.008%
TritonX100 (w/w).
[0084]3.6. Triton X100 Addition for Solubilization and Incubation
[0085]For Virus splitting, TritonX100 is added to a final concentration of 0.5%
(w/w) and incubated over night at room temperature.
[0086]3.7. Diafiltration II
[0087]For removal of the high Triton X100 concentration, Diafiltration is
performed with a 30 kD suspended channel ultrafiltration membrane (Pall). The
Ultraretentate is diafiltrated with 15 retentate volumes of TBS (Tris buffered
saline).
[0088]3.8. Formaldehyde Addition and Incubation
[0089]Formalin is added into the Ultra/Diaretentate to a final concentration of
0.025% for antigen stabilization. The incubation is performed for 18-24 hours at
room temperature. Formalin is a saturated aqueous solution of .about.36-37%
formaldehyde gas.
[0090]3.9. Triton X100 Concentration Determination by HPLC
[0091]Subsequent processing steps consist of a dilution step and a further
Ultra/Diafiltration. In order to be able to dilute the UDR below the CMC for
Triton X 100 (TX 100, .about.0.015%, 250 .mu.M, in aqueous solution), an
analytic TX 100 determination step was introduced to define the concentration of
TX 100. The dilution factor is dependent on this TX 100 concentration.
[0092]3.10. Dilution of the UDR Below the Critical Micellar Concentration for TX
100
[0093]The Ultra/Diaretentate containing residual TX 100 of about 0.1-0.2%
(determined by HPLC) is diluted with TBS to a final TX 100 concentration of
0.008%, a concentration clearly below the CMC (Critical Micellar Concentration).
[0094]3.11. Ultra/Diafiltration III
[0095]Ultra/Diafiltration is performed with the identical 30 kD suspended
channel ultrafiltration membrane. The Ultraretentate is diafiltrated with 5
Retentate volumes of TBS (Tris buffered saline)+5 VC TBS+0.008% TritonX100
(w/w).
[0096]3.12. Detergent Stabilisation
[0097]After reduction of the TX 100 concentration to the target level, Tween 80
is added into the suspension to a final concentration of 0.125%.+-.0,025% for
further virus antigen stabilization. This avoids antigen re-aggregation due to
too low TX 100 concentrations.
[0098]3.13. Second Homogenization
[0099]A second high pressure homogenization step is carried out to keep antigen
loss low at the 0.22 .mu.m filtration step. The same homogenizer as described in
section 3.2 with identical settings is used.
[0100]3.14. Sterile Filtration
[0101]Following the 2nd homogenization step a sterile filtration is carried out
using 0.22 .mu.m filters (Millipore). The sterile filtered Bulk material is
termed Monovalent Bulk (MVB).

4.) Baxter Completes Production of First
Commercial Batches of A/H1N1
Pandemic Vaccine

DEERFIELD, Ill., August 5, 2009 — Baxter International Inc. (NYSE: BAX) today
announced that it completed production of its first commercial batches of
CELVAPAN A/H1N1 pandemic vaccine in late July and is discussing plans for
distribution with national health authorities, subject to obtaining appropriate
authorizations. CELVAPAN, the brand name for the company's A/H1N1 pandemic
influenza vaccine, is made using Baxter's proprietary Vero cell culture
technology.
Baxter plans to deliver initial quantities of CELVAPAN to
national public health authorities that have pandemic agreements with the
company. These health authorities placed orders for the vaccine following the
World Health Organization's (WHO) elevation of the pandemic alert level to phase
6 and declaration of a pandemic.
Baxter's proprietary Vero cell production technology is meeting the company's
expectations to rapidly produce a vaccine in response to a pandemic. CELVAPAN
was developed and commercially produced using this process within 12 weeks of
receiving the A/H1N1 virus strain, which represents an innovation in vaccine
production.
“We are pleased with our company's ability to meet its expected timelines in
developing and producing CELVAPAN,” said Joy Amundson, corporate vice president
and president of Baxter BioScience. “This is an encouraging validation of our
science, our Vero cell vaccine technology and the teamwork at Baxter in meeting
this important milestone to help address an urgent public health issue.”
Baxter is collaborating with regulatory authorities to ensure
the company is in accordance with all requirements needed to support approval
and use of CELVAPAN. “To make CELVAPAN A/H1N1 vaccine, we applied the same
development, qualification and manufacturing processes used in gaining European
Medicines Agency (EMEA) licensure of a mock-up pandemic vaccine,” said Hartmut
J. Ehrlich, M.D., vice president of global research and development for Baxter
BioScience. “The mock-up vaccine made with a different pandemic strain was
tested in five clinical trials worldwide in more than 1,300 people. In addition,
more than 3,500 people have been vaccinated during an ongoing phase III study.”
Confirmatory clinical trials to evaluate safety and immunogenicity of CELVAPAN
A/H1N1 in adults, the elderly and children are scheduled to begin in August.
Baxter has initiated its license application for CELVAPAN A/H1N1 based on the
EMEA published guidelines for pandemic vaccine marketing authorization and will
supplement its application post-approval with the appropriate safety and
immunogenicity data from the confirmatory clinical trials. Once national
vaccination programs are initiated, Baxter will also conduct a large-scale
observational study in people receiving CELVAPAN. In all countries, decisions to
administer the vaccine will be determined by local public health authorities.
ABOUT BAXTER'S PANDEMIC VACCINE DEVELOPMENT
Baxter received the A/H1N1 strain for testing and evaluation from the U.S.
Centers for Disease Control and Prevention (a WHO Collaborating Center) in early
May. The company then undertook pre-production testing and evaluation of the
virus strain to assess its growth characteristics and ability to work in the
company's proprietary Vero cell culture. Based on the virus' ability to grow in
Vero cell culture, Baxter initiated commercial production on June 3, 2009. Bulk
CELVAPAN vaccine is produced at its large-scale commercial facility in Bohumil,
Czech Republic, and is sent to Vienna, Austria for the final formulation, fill
and finish before distribution.
Mock-up licensure is a regulatory pathway for pandemic vaccines that was created
by the European Medicines Agency (EMEA) in 2004. This pathway allows for the
development, evaluation and testing of a company's vaccine production
capabilities using an available influenza strain that has the potential to cause
a pandemic. Once a pandemic is declared and the influenza virus strain causing
the pandemic is identified, the mock-up licensure allows for fast track approval
of a pandemic vaccine containing the actual pandemic strain. Other countries may
choose to evaluate the company's EMEA submission and use that information as the
basis for their national health authority's authorization for use of the
vaccine.

http://finance.yahoo.com/news/Baxter-Gets-H1N1-Marketing-zacks-1470502489.html?x=0&.v=1
Baxter International Inc. (NYSE: BAX - News) recently received marketing
authorization for CELVAPAN H1N1 vaccine, commonly known as the Swine Flu
vaccine, in the European Union. The company has already delivered limited
quantities of H1N1 vaccine to a few countries, such as the UK and Ireland, as
part of their national vaccination programs.
Presently, Baxter is conducting two clinical trials to confirm the safety and
immunogenicity of CELVAPAN H1N1. These trials encompass 400 healthy adults who
are 18 years and above, besides 400 children and adolescents. The safety and
immunogenicity of CELVAPAN H1N1 in these trials are conducted at dose levels of
7.5µg and 3.75µg, respectively. Baxter also plans to conduct a large-scale study
of CELVAPAN in 9,000 people of different age groups including children.
Preliminary safety data in adults for 7.5µg doses of vaccine indicated that the
vaccine was well tolerated in these age groups. The reactions were also similar
to seasonal influenza vaccines. Two 7.5µg doses of vaccine were administered in
a span of 21 days. Immunogenicity data from this study are due within days. This
will indicate whether a single dose of vaccine is sufficient to induce the
necessary immune response.
Another study for 3.75µg doses of vaccine will indicate whether a lower dose is
sufficient to induce the necessary immune response or not.
Baxter is a leading global medical products and services company that develops,
manufactures and markets products to save the lives of millions of people
affected by hemophilia, kidney diseases, infectious diseases, etc.
Baxter’s life-sustaining product portfolio is a hedge against the current
economic turmoil. The company’s main competitors include Becton, Dickinson and
Co. (NYSE: BDX - News) and Johnson & Johnson (NYSE: JNJ - News).

Baxter to evaluate safety of its own H1N1 vaccines in New Zealand »
Baxter scientists who patented the H1N1
“swine flu” vaccine in August 2007 have shares in Baxter and so stand to profit
directly from “recommending” H1N1 flu jab to WHO in conflict of interest
By JB
Baxter, the vaccine company found to have contaminated 72 kilos of vaccine
material with live bird flu virus supplied by WHO in Austria in February 2009,
so nearly triggering a pandemic, has announced an increase of 7.9 per cent in
second quarter profits and is looking forward to a boost in earnings from the
H1N1 flu jab, which has been mandated by WHO in response to the “swine flu”
pandemic, reports WSJ and CLG.
It was Baxter executives, along with their counterparts in Novartis, GSK and
Sanofi, who participated in the vaccine advisory group meeting of WHO on July
7th that recommended H1N1 vaccines for the world’s population.
These H1N1 vaccines were developed by Baxter scientists based
in Austria who also have shares in Baxter, and so stand to make a direct profit
from the demand created by WHO’s instructions to governments to vaccinate all
their populations against the H1N1.
Aso, Baxter’s Austrian-based science team led by Otfried Kistner filed the
provisional application for the H1N1 vaccine in August 2007, reports CLG, almost
two years before the HIN1 virus appeared in April and which the Paris based
World Organization for Animal Health reported had never been seen before.
The fact that the virus had never been seen before in animal
or human strongly suggests the notion that Baxter was instrumental in
biosprospecting for and bioengineering the virus in the first place.
That would explain why Baxter was in a position to file a
patent in August 2007. The existence of this patent also reinforces the notion
that it was Baxter that released the “swine flu” virus in April. After all,
where did it this previously unseen virus come from if not from the lab of the
company that patented it 2 years earlier? A Baxter facility is close to the
location where the “swine flu” first mysteriously appeared in Mexico City.
The Baxter H1N1 application is filed by a team of Austrian,
German staff including Otfried Kistner, Ph.D., and P. Noel Barrett, Ph.D., for
the Baxter H5N1 Pandemic Influenza Vaccine Clinical Study Team, who also report
they have shares in Baxter in a clincial study on that same H1N1 vaccine
published in the New England Journal of Medicine.
CLG reports: “Baxter Vaccine Patent Application US 2009/0060950 A1 –’In
particular preferred embodiments the composition or vaccine comprises more than
one antigen…..such as influenza A and influenza B in particular selected from of
one or more of the human H1N1, H2N2, H3N2, H5N1, H7N7, H1N2, H9N2, H7N2, H7N3,
H10N7 subtypes, of the pig flu H1N1, H1N2, H3N1 and H3N2 subtypes, of the dog or
horse flu H7N7, H3N8 subtypes or of the avian H5N1, H7N2, H1N7, H7N3, H13N6,
H5N9, H11N6, H3N8, H9N2, H5N2, H4N8, H10N7, H2N2, H8N4, H14N5, H6N5, H12N5
subtypes.’
Also, Ehrlich, Kistner and Barret published a clinical trial
in the New England Journal of Medicine ((Previous Volume 358:2573-2584 June 12,
2008 Number 24)
on the safety of an H5N1 whole-virus vaccine produced on Vero cell cultures and
its ability to induce antibodies capable of neutralizing various H5N1 strains,
in which they concluded that the use of adjuvants did not improve the antibody
response.
http://content.nejm.org/cgi/content/short/358/24/2573
And yet Baxter and WHO recommended oil-in-water adjuvants for
the H1N1 “vaccines”.
These adjuvants have been associated with many diseases.
“SAGE recommended that promoting production and use of vaccines such as those
that are formulated with oil-in-water adjuvants and live attenuated influenza
vaccines was important,” says the WHO pandemic briefing note of July 13th.
http://www.who.int/csr/disease/swineflu/notes/h1n1_vaccine_20090713/en/index.html
In addtion, WHO announced on July 16th that countries with
“swine flu” cases no longer need to report them.
Pandemic (H1N1) 2009 briefing note 3
Changes in reporting requirements for pandemic (H1N1) 2009 virus infection
16 JULY 2009 | GENEVA — As the 2009 pandemic evolves, the data needed for risk
assessment, both within affected countries and at the global level, are also
changing.
At this point, further spread of the pandemic, within affected countries and to
new countries, is considered inevitable.
This assumption is fully backed by experience. The 2009
influenza pandemic has spread internationally with unprecedented speed. In past
pandemics, influenza viruses have needed more than six months to spread as
widely as the new H1N1 virus has spread in less than six weeks.
The increasing number of cases in many countries with
sustained community transmission is making it extremely difficult, if not
impossible, for countries to try and confirm them through laboratory testing.
Moreover, the counting of individual cases is now no longer essential in such
countries for monitoring either the level or nature of the risk posed by the
pandemic virus or to guide implementation of the most appropriate response
measures.
And yet the same WHO calims that the “swine flu” has spread
internationally with unprecedented speed. How can WHO know this if it drops the
requirement for countries to suppply data on the speed and spread of that same
virus? How can it track how the virus is mutating without data from countries?
In the July 13th briefing note, WHO places emphasise on collecting data for a
“post-marketing surveillance” and so it is justifiable to ask why WHO does not
want data for a pre marketing surveillance?
“Since new technologies are involved in the production of some
pandemic vaccines, which have not yet been extensively evaluated for their
safety in certain population groups, it is very important to implement
post-marketing surveillance of the highest possible quality. In addition, rapid
sharing of the results of immunogenicity and post-marketing safety and
effectiveness studies among the international community will be essential for
allowing countries to make necessary adjustments to their vaccination policies.”
7.) Flu Kills The Torture Memos

In a 'Holy convenience, Batman!' moment, a 'unique'
flu virus (one likely
concocted
in
US Army labs)
overtakes media coverage of revelations that the
highest levels
of the US government instructed the CIA (and
private contractors)
to torture terror suspects.
Scientists said the virus combines genetic material from pigs, birds and humans
in a way
researchers have not seen before.
“We are very, very concerned,” World Health Organization spokesman Thomas
Abraham said. “We have what appears to be a novel virus
and it has spread from human to human,” he said. “It’s all hands on deck at the
moment.”
Guess where the first swine flu outbreak occurred? That's right,
Fort Dix,
New Jersey, in 1976. Also likely created in a US Army lab. Thirteen soldiers
died, leading the US government to
force
a
questionable vaccine
on the population -- backed by a legal liability escape clause mandated by and
for the pharma-terrorists. Next, people started dying not from the flu -- but
from the *vaccine.*
Every major media outlet has
reported
the fact that US/UK bioterrorists have been

U.S. denies producing biological weapons from bird flu samples
--Media: U.S. denies Indonesia's allegation on bird flu virus 17 Mar 2008 The
United States has flatly denied allegations it was producing biological weapons
from bird flu samples sent by Indonesia to the World Health Organization, the
English daily The Jakarta Post reported Monday. Michael H. Anderson, counselor
for Public Affairs at the U.S. Embassy in Indonesia, [has issued the denial].
However, Indonesian senior biodefense researcher Isro Samihardjo said the
U.S. could use bird flu virus samples from Indonesia to
develop weapons at the Los Alamos Laboratory. Isro was speaking at a
meeting about Health Minister Siti Fadilah Supari's newly released book here
Saturday. In her book "It's Time for the World to Change, Divine Hands behind
Bird Flu," Siti writes of her suspicions about a conspiracy between the U.S. and
the WHO.
Experts identify genes for bird flu
replication
09 Jul 2008 Scientists have identified around 100 genes that the H5N1 bird flu
virus needs in a host in order to replicate, and this finding may help in the
hunt for ways to block foment its proliferation.
Army: 3 vials of virus samples missing
from Maryland facility
22 Apr 2009 Missing vials of a potentially dangerous virus have prompted an Army
investigation into the disappearance from a lab in Maryland. The Army's Criminal
Investigation Command agents have been visiting Fort Detrick in Frederick,
Maryland, to investigate the disappearance of the vials.
The vials contained samples of Venezuelan Equine Encephalitis... In 97
percent of cases, humans with the virus suffer flu-like symptoms, but it can be
deadly in about 1 out of 100 cases, according to Caree Vander Linden, a
spokeswoman for the
U.S. Army Medical Research Institute of
Infectious Diseases.
Scientists isolate genes that made 1918
flu lethal
29 Dec 2008 By mixing and matching a contemporary flu virus with the "Spanish
flu" -- a virus that killed between 20 and 50 million people 90 years ago in
history's most devastating outbreak of infectious disease -- researchers have
identified a set of three genes that helped underpin the extraordinary virulence
of the 1918 virus. Writing today (Dec. 29) in the
Proceedings of the National Academy of
Sciences,
a team led by University of Wisconsin-Madison virologists Yoshihiro Kawaoka and
Tokiko Watanabe identifies genes that gave the 1918 virus the capacity to
reproduce in lung tissue, a hallmark of the pathogen that claimed more lives
than all the battles of World War I combined.
Killer flu recreated in the lab
07 Oct 2004 Scientists have shown that tiny changes to modern flu viruses could
render them as deadly as the 1918 strain which killed millions. A US team added
two genes from a sample of the 1918 virus to a modern strain known to have no
effect on mice. Animals exposed to this composite were dying within days of
symptoms similar to those found in human victims of the 1918 pandemic.
Venture capital firm set to reap rewards

of the two public companies in the firm's portfolio of eight Pandemic and Bio
Defense companies -- BioCryst Pharmaceuticals and Novavax -- jumped Friday on
news that the swine flu killed a reported 60 people in Mexico and has infected
people in the United States. The World Health Organization said the [unique]
virus appears to be susceptible to Roche's flu drug
Tamiflu, also known as oseltamivir, but not to older flu drugs such as
amantadine.

good news for Defense Secretary Donald Rumsfeld and other politically
connected investors in Gilead Sciences, the California biotech company that owns
the rights to Tamiflu, the influenza remedy that's now the most-sought after
drug in the world. Rumsfeld served as Gilead (Research)'s chairman from 1997
until he joined the Bush administration in 2001, and he still holds a Gilead

--Unique virus connected to cases in Calif. and Texas;
source still a mystery 24 Apr 2009 Mexico shut down schools, museums,
libraries and state-run theaters across its overcrowded capital Friday in hopes
of containing a swine flu outbreak that authorities say killed at least 20
people -- and perhaps dozens more. World health authorities worried openly that
the strange new virus could become a global epidemic. The U.S. Centers for
Disease Control and Prevention said tests show some of the Mexico victims died
from the same new strain of swine flu that sickened eight people in Texas and
California. Of the 14 samples tested from Mexico, seven were matches, said the
CDC's acting director Dr. Richard Besser.
'Laboratory testing showed that the virus does not match any known flu strains.'
In California and Texas, 5 New Swine Flu
Cases
24 Apr 2009 Government scientists have identified five more people who have been
infected with swine flu, apparently confirming suspicions that the unusual
strain of the respiratory infection is spreading from person to person, federal
health officials said yesterday. Three new cases were found in California and
two in Texas, bringing the total number of confirmed cases to seven, officials
at the federal Centers for Disease Control and Prevention in Atlanta said...
Genetic analysis of the virus indicates it is highly unusual: It is a hybrid
that resulted from a [Fort
Detrick?]
combination of four different viruses.'
Troops Could Be Sent to Border
--Under $350M plan, National Guard would be aimed at drug war 24 Apr 2009 The
Pentagon and Homeland Security Department are developing contingency plans to
send National Guard troops to the U.S.-Mexican border under a $350 million
initiative that would expand the U.S. military's role in [fomenting] the drug
war, according to Obama administration officials.
In 2002, Military Agency Warned Against
'Torture'
--Extreme Duress Could Yield Unreliable Information, It Said 24 Apr 2009 The
military agency that provided advice on harsh interrogation techniques for use
against terrorism suspects referred to the application of extreme duress as
"torture" in a July 2002
document
sent to the Pentagon's chief lawyer and warned that it would produce "unreliable
information." "The unintended consequence of a U.S. policy that provides for the
torture of prisoners is that it could be used by our adversaries as
justification for the torture of captured U.S. personnel," says the document, an
unsigned two-page attachment to a memo by the military's
Joint Personnel Recovery Agency.
Parts of the attachment, obtained in full by The Washington Post, were quoted in
a Senate report on harsh interrogation released this week. [Oops! Looks like the
PentaPost will have to stop calling torture 'enhanced interrogation techniques'
because the Pentagon itself calls torture torture. --LRP]

8.) Stop Baxter International
Source:
http://www.thepetitionsite.com/1/stop-baxter-international-from-developing-the-h1n1-vaccine
This petition is no longer about stopping Baxter from making the H1N1 vaccine as
it s too late, but it is now about getting enough signatures to have them
investigated and hopefully shut down.
Baxter International is a drug company that has been at the center of three
major drug contamination scandals, one of them occurred only a few months ago in
February of this year:
1. Live avian flu was found in flu vaccines intended for human use:
http://www.torontosun.com/news/canada/2009/02/27/8560781.html
2. They sent out Heparin that did not even contain the main ingredient, but
instead contained a chemically similar compound:
http://www.nowpublic.com/health/heparin-blood-thinner-baxter-partially-contaminated-fda-announced
3. And in the 1980's the FDA banned Baxter from using certain blood products
known to contain HIV and AIDS. So what did they do? They sold them to foreign
countries with no warning about what they contained:
http://www.businessweek.com/archives/1996/b3466083.arc.htm
Two instances is a trend, but three is a pattern. All of these contaminations
were carried out with prior knowledge and were therefore malicious acts.
Still, the WHO selected Baxter to create the H1N1 vaccine just two months after
live avian flu was found in vaccines intended for human use. As well, it has
been revealed that due to the fact it was made in a Biohazard safety level 3
facility, these two substances, a live deadly virus and a flu vaccine, could
never come into contact accidentally.
As a country, as a global community, we cannot allow this to continue. Baxter is
not capable of safely manufacturing products for human use and should not be
allowed to do so. Please sign this petition, and pass it on to everyone you know
and love, so we can keep ourselves safe from harm.
I was recently contacted by the someone from this petition site saying a
reported called them wanting to interview me about this petition. I bought it
and phoned and left my full name and number and they never called back. I looked
up the name of the person I called and it turned her name was no where on the
site of the company she said she worked for. Baxter has my info and that is
scary.
As well, I am not longer allowed to share this petition on Facebook because
'someone' reported it as abusive and it is now banned. I need your help. It is
scary out here.
Thank you for your time.

10.) Virginia Teen Suffers Severe Adverse Effects
After Getting H1N1 & Seasonal Flu Shots
11
november 2009
Source:
http://www.wusa9.com/news/local/story.aspx?storyid=93619&catid=168
ALEXANDRIA, Va. (WUSA) --- An active and healthy 14-year-old can barely walk
after taking the
H1N1
and seasonal flu vaccines.
Jordan McFarland has been diagnosed with a rare disease that is triggered by the
flu shots.
It's called Guillain Barre Syndrome, an extremely rare disorder that causes a
patient's immune system to attack the nerves.
McFarland came down with symptoms within 24 hours of taking the two
vaccinations.
"I
got cold really quickly," he said one day after being released from the
hospital. "I got a headache and I got dizzy. Slowly, these things progressed
until the end of the day when I started having back spasms and I couldn't walk."
McFarland was admitted at Inova Fairfax Hospital in Falls Church, where he was
diagnosed with GBS. Doctors were able to stop the most serious adverse effects
but the teen still faces a long, painful and tiring recovery. He's been told it
could take 6-8 weeks of physical therapy before he's fully recovered.
"It's been quite traumatic to watch your son not have the ability to control
himself," said his dad, Calvin McFarland. "I had a hard time watching him move
around spastically, knowing he was in so much pain and not being able to do
anything about it."
"In a sense, as a parent you do carry a little sense of guilt because your kids
trust you," he continued. "Kids trust their parents. Parents trust your
doctors."
Doctors cannot tell family members whether Jordan's GBS was caused by the timing
of both vaccinations, which were within 24 hours of each other or by the H1N1
vaccine. Jordan and his 6-year-old brother Lleyton received the shots last week.
Only six cases of GBS following the H1N1 vaccine have been reported to the
Center for Disease Control. Compared to the roughly 40 million people who
received shots, experts say the risk is not nearly as scary as contracting the
H1N1 virus.
Even still, the McFarlands want other parents to at least be aware of the
possibility.
"The same effects have occurred behind the regular flu shots as well," said the
38-year-old father. "It makes me nervous. You feel like you're playing Russian
Roulette.
Just roll the dice and see what happens."
11.) Riesgo de complicaciones graves
relacionadas con influenza supera ampliamente el riesgo de las vacunas
inyectables en mujeres embarazadas
31 Octubre 2009
Fuente:
http://articulos.sld.cu/influenzaporcina/2009/10/31/riesgo-de-complicaciones-graves-relacionadas-con-influenza-supera-ampliamente-el-riesgo-de-las-vacunas-inyectables-en-mujeres-embarazadas/
Las mujeres embarazadas que contraen la influenza corren un grave riesgo por las
complicaciones relacionadas con la ella, incluida la muerte, y este riesgo es
mucho mayor que el riesgo de posibles efectos secundarios de las vacunas
inyectables que contengan virus muertos, según arrojó una amplia revisión de
información e investigaciones publicadas sobre previas influencias estacionales.
La revisión, una colaboración entre científicos del Johns Hopkins Children’s
Center, la Universidad de Emory y del Hospital Infantil de Cincinnati, y
publicada el 22 de octubre en la edición en línea del American Journal of
Obstetrics & Gynecology, encontró evidencia sustancial y persistente de alto
riesgo de complicaciones para las mujeres embarazadas — tanto en las sanas como
en aquellas con condiciones médicas subyacentes - infectadas con el virus de la
influenza, además de confirmar la seguridad de la vacuna. Los hallazgos, dicen
los investigadores, solidifican las recomendaciones de los CDC que hacen que las
mujeres embarazadas sean el grupo de mayor prioridad para recibir tanto las
vacunas de la influenza H1N1 y la estacional.
“Las lecciones aprendidas de los brotes de influenza en el pasado lejano y no
muy lejano son claras y también lo son los mensajes”, dice el investigador
principal Pranita Tamma, MD, especialista en enfermedades infecciosas del Johns
Hopkins Children’s Center. “Si usted es una mujer embarazada, vacúnese. Si usted
es médico obstetra, inste a sus pacientes a vacunarse.”
http://www.medicalnewstoday.com/articles/169242.php
Because even healthy pregnant women end up in the hospital with preventable flu
complications — some devastating and some fatal — at a rate far higher than that
of other adults, and because of the proven effectiveness and overall safety
record of flu vaccines, all pregnant women should consider getting vaccinated to
prevent complications in both the expectant mother and her offspring,
researchers say.
“Healthcare providers will play a key role in women’s decisions about whether or
not to be vaccinated against H1N1,” says study senior investigator Saad Omer,
M.B.B.S., M.P.H. Ph.D., of Emory University. “There is substantial evidence that
vaccination is not only safe for pregnant women but that it is critical for
protecting women and their infants against serious complications from the flu.
Physicians and other providers should talk about risks and benefits with their
patients and help alleviate any unfounded fears.”
Even though there are still no published data on the safety of the new H1N1
vaccine, experts believe it to be just as safe as the seasonal flu vaccine,
Johns Hopkins’ Tamma says, because “the H1N1 vaccine is manufactured in the same
rigorous way as the seasonal flu vaccines and we expect it to have a very
similar safety profile as the other flu vaccines.”
In their extensive review of data from three past flu pandemics and 11 published
research studies on vaccine safety outcomes over 44 years, the researchers found
no increased risk of either maternal complications or bad fetal results from the
inactivated (injection) flu vaccine.
Researchers point out that even though study after study has found no link
between the vaccine stabilizer thimerosal and autism, thimerosal-free injectable
versions of the flu vaccine are available for those who have lingering concerns.
In their review, researchers say four studies have found evidence that
antibodies protective against the flu, developed by the mother after
vaccination, cross the placenta and transfer some protection to the fetus that
lasts up to six months after birth.
Because pregnancy causes a variety of changes in the body, most notably
decreased lung capacity, along with increased cardiac output and oxygen
consumption, it puts pregnant women at high risk for complications. In addition,
parts of the mother’s immune system are selectively suppressed, a process that
offers essential protection to the fetus, but decreases the mother’s ability to
fight off infection.
Other findings in the review:
– In the first four months of the H1N1 flu outbreak this spring, pregnant women
were hospitalized at four times the rate of other healthy adults infected with
the virus, according to the CDC.
– Pregnant women made up 13 percent of all H1N1 deaths during that period, and
most of the women who died were previously healthy.
– Pregnant women do not get infected with the flu more often than other adults,
but they develop more serious complications and more often. Pregnant women with
underlying conditions such as asthma or diabetes are at even higher risk for
complications.
– During the 1918 Spanish flu pandemic, of the 1,350 flu-infected pregnant women
who were studied, half developed pneumonia, and more than half of those who did
so died, with most deaths occurring during the third trimester.
– During the 1957 pandemic, nearly half of all women of childbearing age who
died of the flu were pregnant.
– Eleven clinical studies closely followed pregnant women and/or their fetuses
after vaccination and found no evidence of harmful side effects in either the
mother or the fetus.
– The Vaccine Adverse Event Reporting System database, a national repository of
self-reports of adverse vaccine effects, showed 26 reports of adverse effects
between 2000 and 2003, a period during which 2 million pregnant women were
vaccinated against the flu. Of the 26 reports, six had to do with wrongly
administered vaccine without any negative consequences; nine reports described
brief injection site tenderness; eight involved systemic symptoms, such as
malaise and fever; and three were miscarriages. Investigators point out that
these are self-reported events and do not establish any evidence of cause and
effect either with respect to either miscarriage or side effects.
The research was funded partially by an NIH fellowship training grant to Pranita
Tamma. Co-investigator Neal Halsey, M.D., of Johns Hopkins, receives grant
support from NIH, CDC, Berna, Intercel, Merck and Novartis, none of which went
toward this particular research.
Other investigators in the study include Kevin Ault, M.D., and Carlos Del Rio,
M.D., of Emory University; and Mark Steinhoff, M.D., of Cincinnati Children’s
Hospital.

13.)Adverse reactions to H1N1 vaccine few, far
between
Benefit
of shot outweighs risk, experts suggest
By Pauline Tam, The Ottawa CitizenNovember 11, 2009
http://www.ottawacitizen.com/health/Adverse+reactions+H1N1+vaccine+between/2209017/story.html
Public-health
officials in Ottawa have received 19 confirmed reports of allergic reactions to
the H1N1 flu shot since the city's vaccination campaign began more than two
weeks ago.
Of that number, seven people were transferred to hospital emergency rooms, but
to date, none has required hospitalization, said Dr. Nadine Sicard, Ottawa's
associate medical officer of health.
Another 11 cases are being investigated by health officals to determine whether
they were, indeed, adverse reactions. In addition, one person was hospitalized
for a reaction that was "temporarily associated, although not directly related
to the vaccine," Sicard said in an e-mail. She did not provide further details.
To date, 140,000 residents, mostly those at high risk of developing
complications from swine flu, have received the pandemic vaccine. That suggests
0.01 per cent, or one in 10,000 people who were vaccinated, have so far had a
suspected allergic reaction to the shot.
"This is within the expected range for a vaccine," said Sicard. Adverse
reactions can range from a sore arm, which is common and does not require
medical treatment, to dizziness or fainting. Serious adverse reactions that
require immediate medical attention include an anaphylactic response, in which
the throat closes, blood pressure plunges and airways tighten.
The maker of the H1N1 vaccine, GlaxoSmithKline, warns that up to one in 1,000
doses may result in an allergic reaction leading to a "dangerous decrease of
blood pressure."
Sicard said early data suggests about one in 1,000 Ottawa residents who have
received the shot have reported some reaction within 15 minutes of getting it.
"These are mostly hives and tingling on the tongue that we would regard as
significant and reportable," said Sicard. "Some have been fainting episodes and
a handful have been clinical allergic reactions requiring treatment."

Seasonal Flu, H1N1 Medications – Side Effects, Adverse Reactions & Cautions
Source:
http://www.wellsphere.com/health-education-article/seasonal-flu-h1n1-medications-side-effects-adverse-reactions-cautions/828778
Posted Oct 07 2009 2:57pm
This post summarizes possible
side-effects and cautions that are important to be aware of while using
common antiviral agents both for the seasonal flu and a
Novel H1N1
infection. These awareness guidelines apply to both adults and
children; and additionally, are important for pregnant women to bear in
mind as well.
ZANAMIVIR:
The drug Zanamivir is licensed only
for use in persons without underlying respiratory or cardiac
disease. Post marketing surveillance as well as some studies indicate
that respiratory function deterioration can occur after inhalation of
Zanamivir by those who have underlying airway disease. For this
reason, this drug is not recommended for patients with such an
underlying condition. Post marketing surveillance has also included
reports of allergic reactions such as oropharyngeal or facial edema in
some cases with the use of this drug.
Other common adverse events
reported by those using Zanamivir include diarrhea, nausea, sinusitis,
nasal signs and symptoms, bronchitis, cough, headache, dizziness, and
ear, nose, and throat infections. Each of these symptoms was reported
by less than 5% of persons in the clinical treatment studies.
OSELTAMIVIR:
Relative to Zanamivir, a greater
number of unpleasant side-effects appear to have been reported with the
use of the antiviral medication, Oseltamivir. In clinical treatment
trials, nausea and vomiting were reported more frequently among adults
receiving Oseltamivir for treatment (nausea without vomiting,
approximately 10%; vomiting, approximately 9%) than among persons
receiving placebo (nausea without vomiting, approximately 6%; vomiting,
approximately 3%). Among children treated with Oseltamivir, 14% had
vomiting, compared with 8.5% of placebo recipients. It is recommended
that Oseltamivir be taken with food to help reduce the severity of
nausea and vomiting.
Another concern with respect to the
use of Oseltamivir has been reports of transient neuro-psychiatric
events (such as self-injury or delirium) that appear to have been
associated with its use. Currently, the FDA has advised that persons
taking Oseltamivir be monitored closely for abnormal behavior.
AMANTADINE &
RIMANTADINE:
At a dosage of 200 mg/day, both
Amantadine and Rimantadine can cause Central Nervous System (CNS) and
gastro-intestinal side-effects when given to young, healthy adults.
Data suggest that incidence of CNS side effects (e.g., nervousness,
anxiety, insomnia, difficulty concentrating, and lightheadedness) is
higher among persons taking Amantadine than among those taking
Rimantadine. Generally, side effects associated with both these drugs
are mild and cease when the drug is discontinued. However, serious side
effects have been observed (e.g., marked behavioral changes, delirium,
hallucinations, agitation, and seizures) among persons who have renal
insufficiency, seizure disorders, or certain psychiatric disorders and
also among older persons who have been taking Amantadine as prophylactic
treatment at a dose of 200 mg/day.
DRUG INTERACTIONS:
Data vis-a-vis drug interactions is
limited with respect to both Zanamivir and Oseltamivir. With regard
to the use of the drug Amantadine, caution is advised in using
it concurrently with drugs that effect the CNS, including CNS
stimulants. The concomitant administration of antihistamines or
anticholinergic drugs can also increase the incidence of adverse CNS
reactions in patients. Currently, no published data are available
concerning the safety or efficacy of using combinations of any of these
influenza antiviral drugs. For this reason, awareness and cautions must
always be borne in mind while using these medications.
Use this link to refer to helpful criteria for
discerning an adverse drug event/interaction.
SAFETY ISSUES DURING
PREGNANCY:
The four drugs discussed above fall
under “Pregnancy Category C” medications, which
indicates that no clinical studies have been conducted to assess the
safety of these medications for pregnant women. Both Amantadine and
Rimantadine have been demonstrated in animal studies to be
teratogenic (i.e., able to disturb the growth and development of an
embryo or fetus) and embryotoxic when administered at
substantially high doses. CDC recommends that the antiviral medications
discussed here should be used during pregnancy only if the potential
benefit justifies the potential risk to the embryo or fetus, and
further, that the manufacturers’ package inserts should be consulted
prior to the use of these medications.
With an astute awareness on how to
use drugs safely, a great many potentially serious adverse events can
either be circumvented altogether or treated promptly. If you are
currently dealing with the seasonal flu or an H1N1 infection, stay on
the alert while using prescribed medications, and use them according to
the parameters provided. You may also want to keep the above
information handy or pass it on to others who may benefit.

15.) Lancet recommends
caution for H1N1 vaccinations; ajduvants merit concern
|
|
Teresa Binstock
Researcher in Developmental & Behavioral Neuroanatomy
August 09, 2009
Once again, a specter of flu haunts the media. Messages are conflicted.
News media repeatedly mention that the H1N1 flu is generally mild, even
as we are told to fear the H1N1 swine flu.
Irony abounds. Often, flu vaccines in prior flu seasons have been found
to be ineffective because that season's vaccine strain was not identical
to the wild-type strain that became widespread, yet recent media reports
tell us that an H1N1 vaccine will be effective even if H1N1 mutates into
a different strain.
The Lancet - a peer-reviewed medical journal - recently editorialized on
behalf of caution in regard to fast-tracking mass vaccinations (1).
After free registration, the essay can be viewed online. Oddly, The
Lancet editorial mentions vaccine adjuvants but does not dwell upon
their documented side-effects. Indeed, several vaccine ingredients merit
concern, including mercury, aluminum, live viruses, and squalene.
For instance, despite assurances that thimerosal injections do no harm,
an increasing body of peer-reviewed evidence describes adverse effects
of vaccinal thimerosal (eg, 2). Aluminum is associated with
neurodegeneration (eg, 3), and the adjuvant squalene is associated with
arthritic pathologies and with Gulf War Syndrome (4-6).
Questions need be answered. Why is there a mass vaccination program with
vaccines untested for safety when H1N1 swine flu cases are generally
mild? Why a massive anti-H1N1 vaccination program when the rapidly
developed H1N1 vaccine may not be effective against a mutated strain,
when various H1N1 vaccine ingredients have a record of toxicity and
adverse effects?
I am saddened by a possibility: Is the creating of chronic pathologies
by means of vaccination an unstated intention of pharmaceutical
companies and their eager servants in the FDA and CDC? Alternatively,
has vaccinology become dominated by True Believers who shun findings of
adverse effects?
Conclusion & recommendation: This brief essay calls attention to ironies
in the so-called "H1N1 pandemic" and amid hoopla urging mass vaccination
without real testing for safety. Via several online essays (4-5) and a
well written, thoroughly citationed book (4b), individuals who may be
subjected to untested vaccines are encouraged to read more about
squalene and other adjuvants which hyper-stimulate immunity and have a
track record of adverse effects.

This study investigated the association between vaccination with the
Hepatitis B triple series vaccine prior to 2000 and developmental
disability in children aged 1-9 years (n = 1824), proxied by parental
report that their child receives early intervention or special education
services (EIS). National Health and Nutrition Examination Survey
1999-2000 data were analyzed and adjusted for survey design by Taylor
Linearization using SAS version 9.1 software, with SAS callable SUDAAN
version 9.0.1. The odds of receiving EIS were approximately nine times
as great for vaccinated boys (n = 46) as for unvaccinated boys (n = 7),
after adjustment for confounders. This study found statistically
significant evidence to suggest that boys in United States who were
vaccinated with the triple series Hepatitis B vaccine, during the time
period in which vaccines were manufactured with thimerosal, were more
susceptible to developmental disability than were unvaccinated boys.

Effects of aluminum on the nervous system and its possible link with
neurodegenerative diseases
Kawahara M.
J Alzheimers Dis. 2005 Nov;8(2):171-82.
Aluminum is environmentally abundant, but not an essential element.
Aluminum has been associated with several neurodegenerative diseases,
such as dialysis encephalopathy, amyotrophic lateral sclerosis and
Parkinsonism dementia in the Kii peninsula and Guam, and in particular,
Alzheimer's disease. Although this association remains controversial,
there is increasing evidence which suggests the implication of metal
homeostasis in the pathogenesis of Alzheimer's disease. Aluminum, zinc,
copper, and iron cause the conformational changes of Alzheimer's
amyloid-beta protein. Al causes the accumulation of tau protein and
amyloid-beta protein in experimental animals. Aluminum induces neuronal
apoptosis in vivo as well as in vitro. Furthermore, a relationship
between aluminum and the iron-homeostasis or calcium-homeostasis has
been suggested. Based on these findings, the characteristics of aluminum
neurotoxicity are reviewed, and the potential link between aluminum and
neurodegenerative diseases is reconsidered.
