This brings us to the other major slogan of the rally, namely “Too
Many, Too Soon.” This, too, is a conveniently vague but
oh-so-reasonable-sounding slogan. It, like “Green Our Vaccines,”
is also another strategy to move the goalposts. The concept is based
on the expansion of the number of recommended vaccines since 1983.
Confusing correlation with causation yet again, anti-vaccine
activists make the observation that the prevalence of autism has
increased markedly since 1983, when the number of vaccines
recommended for infants and small children was ten, to now, when the
recommended number is 36. Indeed, this was a huge component of
Generation Rescue’s deceptive full-page advertisement in USA
Today that appeared
back in February. The concept is simple. It is
postulated that the increasing number of vaccines somehow
“overwhelms” the immune system or causes some sort of “aggregate”
toxicity that is responsible not just for autism, but a variety of
chronic diseases, such as obesity and type II diabetes, asthma, and
autoimmune diseases. That there is no even mildly compelling
scientific or epidemiological evidence to support these claims
doesn’t matter. Antivaccinationists have thus far successfully
wrapped themselves in the mantle of caution that to most parents
without a background in science or epidemiology seems eminently
reasonable. It also sounds, on the surface at least, eminently
reasonable when antivaccination activists claim that it’s the
combination of vaccines that cause all these neurodevelopmental
problems like autism. It’s also a conveniently difficult to falsify
claim. Clearly activists have learned from their mistake with
never to make a hypothesis that makes a relatively easily testable
prediction. The thimerosal hypothesis made the prediction that if
thimerosal in vaccines were removed autism prevalence should fall
rather rapidly within 5-7 years, given that the age range when most
autism is diagnosed is from 3 to 5. Autism prevalence hasn’t
fallen; it’s still
rising. Even those who claimed that “it’s the
mercury, stupid” and that “autism is a misdiagnosis for mercury
poisoning” now realize that neither of these statements is true.
The most that can be said from current data is that maybe, just
maybe, a very small number of susceptible children could have a
reaction that might manifest itself as autistic symptoms–hence the
moving on to other “toxins.” In contrast, the “Too Many, Too
Soon” hypothesis is much vaguer and difficult to extract easily
testable hypotheses from, which is the whole point of it.
Of course, no scientific evidence is ever presented that rises
above the level of Dr. Laura Hewitson’s badly
designed monkey study, Generation Rescue’s even
poorly designed “telephone
survey” of vaccinated and unvaccinated
Dan Olmsted’s easily
falsified claim that the Amish do not vaccinate
not get autism to support their contention that the current vaccine
schedule is harmful. Moreover, when the GOV movement claims that
current vaccines haven’t been tested in combinations, it’s just
plain wrong. All new vaccines are tested in clinical trials against
the background of the current vaccine schedule. In other words, if
it’s a new vaccine not currently recommended, in clinical trials
it’s merely added to the current schedule. If the vaccine is for
the same disease as a currently used vaccine, then the trial looks
the new vaccine versus the old vaccine, all other vaccines in the
schedule remaining the same. The reason we don’t do serial
“one-at-a-time” trials is simple, but nonetheless
antivaccinationists never seem able to grasp the concept: It would
extremely unethical to withhold protective vaccines from children in
order to test them against no vaccines because it would leave the no
vaccine group of children vulnerable to vaccine-preventable
In reality, this is yet another thinly-disguised attempt to move the
goalposts. More savvy antivaccinationists know that the kind of
testing they demand is unethical, prohibitively expensive, and
impractical, but demanding it allows them to claim (falsely) that
there is no science supporting the safety of the current vaccine
schedule and provide a complaint that sounds as though it has merit
to those without a background in medicine and clinical trials.
Moreover, contrary to the claims that the current vaccine schedule
“overloads the immune system,” there are actually fewer antigens
now in more vaccines, thanks to better vaccine design. Like the
“Green Our Vaccines” slogan, the “Too many, too soon” slogan
is also nothing more than a fairly clever strategy of preemptively
moving the goalposts. Conveniently, the GOV folks never quite tell
which vaccines should be delayed and why or what the tradeoff would
be in terms of exposing children to vaccine-preventable disease for
longer period of time before they are vaccinated. That’s not the
point. Casting doubt on the safety and efficacy of vaccines is.
In addition, Generation Rescue released a phone survey in 2007
they claimed, demonstrated that vaccinated children were more than
2.5 times as likely to develop autism and attention
hyperactivity disorder than were unvaccinated
however, this study was not published in a peer-reviewed journal and
its methodology has been sharply criticized.
CDC study produced estimates of autism prevalence that were
consistent with previous studies. In contrast, J. B.’s survey
produced estimates of autism and ASDs of 3% in the aggregated data.
That’s 1 in 33, approximately 5 times more prevalent than the
usually cited estimate of 1 in 166 or 1 in 150. This, too, suggests
reporting bias, where parents who have a child with autism or an ASD
will be more likely to complete this survey.
coupled with all the other problems in the alleged “statistical
analysis,” it likely does. Any major interaction between the two
main sets of questions that might produce different biases in the
different groups would, unless carefully controlled for, invalidate
the study. There’s no evidence that SurveyUSA did any of that.
Moreover, SurveyUSA is known for asking very concise questions that
have been known in the past to produce divergent results using
automated telephone polls, which have a number of problems, not the
least of which is a much lower
rate than traditional polls. Again, the issue
of reporting bias comes up. That’s not to say that it’s not
possible to do accurate polls with automated technology, but asking
about health problems is difficult, leading me to take any such poll
done looking for correlations between vaccines and anything with a
huge grain of salt. Moreover, no evidence about response rates or
many parents responded “not sure” for each question is presented,
nor is any evidence to show that the sample chosen is
I also can’t help but note that the introduction, in which it is
stated that “we’ve been hired by a private organization to study
the relationship between vaccines and the health of Sonoma County
children.” and it is denied that SurveyUSA is “working for the
government,” a school system, or a public agency. That sets up an
association right there that could lead to bias.
I’ve heard people talk about “simultaneous”
and “combination” vaccines. What does this mean? Why are vaccines
administered this way?
A combination vaccine consists of two or more different vaccines
that have been combined into a single shot. Combination vaccines
been in use in the United States since the mid-1940's. Examples of
combination vaccines in current use are: DTaP
(diphtheria-tetanus-pertussis), trivalent IPV (three strains of
inactivated polio vaccine), MMR (measles-mumps-rubella), DTaP-Hib,
and Hib-Hep B (hepatitis B). Simultaneous vaccination is when more
than one vaccine shot is administered during the same doctor's
usually in separate limbs (e.g. one in each arm). An example of
simultaneous vaccination might be administering DTap in one arm or
leg and IPV in another arm or leg during the same visit.
Giving a child several vaccinations during the same visit offers
two practical advantages. First, we want to immunize children as
quickly as possible to give them protection during the vulnerable
early months of their lives. Second, giving several vaccinations at
the same time means fewer office visits. This saves parents both
and money, and may be less traumatic for the child.
Is simultaneous vaccination with multiple
vaccinations safe? Wouldn't it be safer to separate vaccines and
spread them out, vaccinating against just one disease at a time?
The available scientific data show that simultaneous vaccination
with multiple vaccines has no adverse effect on the normal childhood
immune system. A number of studies have been conducted to examine
effects of giving various combinations of vaccines simultaneously.
These studies have shown that the recommended vaccines are as
effective in combination as they are individually, and that such
combinations carry no greater risk for adverse side effects.
Consequently, both the Advisory Committee on Immunization Practices
and the American Academy of Pediatrics recommend simultaneous
administration of all routine childhood vaccines when appropriate.
Research is underway to find methods to combine more antigens in a
single vaccine injection (for example, MMR and chickenpox).
Can so many vaccines, given so early in life,
overwhelm a child's immune system, suppressing it so it does not
No evidence suggests that the recommended childhood vaccines can
“overload” the immune system. In contrast, from the moment babies
are born, they are exposed to numerous bacteria and viruses on a
daily basis. Eating food introduces new bacteria into the body;
numerous bacteria live in the mouth and nose; and an infant places
his or her hands or other objects in his or her mouth hundreds of
times every hour, exposing the immune system to still more antigens.
When a child has a cold they are exposed to at least 4 to 10
and exposure to “strep throat” is about 25 to 50 antigens.
Adverse Events Associated with Childhood Vaccines, a 1994
report from the Institute of Medicine, states: “In the face of
these normal events, it seems unlikely that the number of separate
antigens contained in childhood vaccines ...would represent an
appreciable added burden on the immune system that would be

which a little boy who had just entered school died of

- In 2012, there were 122 000 measles deaths globally – about

- Measles vaccination resulted in a 78% drop in measles deaths
between 2000 and 2012 worldwide.
- In 2012, about 84% of the world's children received one dose
of measles vaccine by their first birthday through routine
health services – up from 72% in 2000.
- Since 2000, more than 1 billion children in high risk
countries were vaccinated against the disease through mass
vaccination campaigns ― about 145 million of them in 2012.
Before the introduction of measles vaccines, measles virus infected
95%–98% of children by age 18 years [1–4],
measles was considered an inevitable rite of passage. Exposure
was often actively sought for children in early school years because
of the greater severity of measles in adults.
Complications with measles are relatively common, ranging from mild

persons (e.g., people with AIDS)
the fatality rate is approximately 30%.
Consequences of Failure to Vaccinate
A recent study44
in Colorado demonstrated that children who were exempted from
immunization were 22 times more likely to develop measles and
almost six times more likely to acquire pertussis than vaccinated
children. School was the site of infection in more than 20 percent
of the children who developed measles or pertussis. In this study,
each 1 percent increase in children exempted from immunization
increased the risk of a pertussis outbreak by 12 percent.44
Because immunizations against measles and pertussis are not 100
percent effective, there was a 60 percent and a 90 percent annual
increased risk of measles and pertussis among vaccinated children
three to 18 years of age for each 1 percent increase in the
proportion of unimmunized children (exemptors) by county.44
Consequently, the choice of some parents not to immunize their
children increases the risk for children who are immunized. These
parents may not realize that the individual choice not to
vaccinate a child has public health consequences.
In 1900, for every 1,000 babies born in the United States, 100
would die before their first birthday, often due to infectious
diseases. Today, vaccines exist for many viral and bacterial
diseases. The National Childhood Vaccine Injury Act, passed in 1986,
was intended to bolster vaccine research and development through the
federal coordination of vaccine initiatives and to provide relief to
vaccine manufacturers facing financial burdens. The legislation also
intended to address concerns about the safety of vaccines by
instituting a compensation program, setting up a passive
system for vaccine adverse events, and by providing information to
consumers. A key component of the legislation required the U.S.
Department of Health and Human Services to collaborate with the
Institute of Medicine to assess concerns about the safety of
and potential adverse events, especially in children.
Effects of Vaccines reviews the epidemiological, clinical,
biological evidence regarding adverse health events associated with
specific vaccines covered by the National Vaccine Injury
Program (VICP), including the varicella zoster vaccine, influenza
vaccines, the hepatitis B vaccine, and the human papillomavirus
vaccine, among others. For each possible adverse event, the report
reviews peer-reviewed primary studies, summarizes their findings,
evaluates the epidemiological, clinical, and biological evidence. It
finds that while no vaccine is 100 percent safe, very few adverse
events are shown to be caused by vaccines. In addition, the evidence
shows that vaccines do not cause several conditions. For example,
MMR vaccine is not associated with autism or childhood diabetes.
Also, the DTaP vaccine is not associated with diabetes and the
influenza vaccine given as a shot does not exacerbate asthma.
Rare vaccine side effects
A far less common but serious vaccine side effect is an
immediate allergic reaction, also known as an anaphylactic
reaction. These are dramatic and potentially
life-threatening; however, it should be noted that they occur
very rarely (fewer than one in a million) and are completely
reversible if treated promptly by healthcare staff.
To have a balanced view, potential side effects have to be weighed
against the expected benefits of vaccination in preventing the
serious complications of disease.

risks of vaccination.
Not all illnesses that occur following vaccination will be a side
effect. Because millions of people every year are vaccinated,
it's inevitable that some will go on to develop a
coincidental infection or illness shortly afterwards.

les réponses à vos questions.
Dès sa 14ème

composent sont les lymphocytes T qui détruisent toutes cellules
inconnues et les lymphocytes B qui produisent des anticorps

Quand bébé naît, il possède des anticorps qui lui ont été
transmis par sa maman. Le nouveau-né doit rapidement s’adapter
à l’environnement bactérien qui l’entoure. Pas d’inquiétude,
bébé est plus que prêt. D’ailleurs, il possède beaucoup plus de
lymphocytes qu’un adulte. La nature est bien faite, l’organisme
comprend vite qu’il va devoir se défendre. Malgré tout, Bébé

to produce IFN-γ and of neonatal DCs to promote Th1 responses is
lower in infants as compared to adults. In
vivo, Th1 responses to a number of vaccines and infectious
pathogens are poor during early life. However, mature Th1 responses
can develop in certain conditions such as neonatal BCG vaccination
and Bordetella pertussis infection, probably in relation
with a more efficient activation of DCs. In vitro studies
well as clinical investigations also suggest that the priming of
neonatal CD8 T cell responses may require a lower threshold of DC
activation than that required for Th1 responses. Other features of
neonatal T lymphocytes include homeostatic proliferation and
increased susceptibility to apoptosis, but the impact of this high

molecular pathways leading to DC and T cell activation in human
neonates will lead to the development of new vaccines eliciting

Because of better hygiene and sanitation, hadn’t
diseases already begun to disappear before vaccines
No, they had not begun to disappear. In the 20th
century, infectious diseases began to be better controlled because
improvements in hygiene and sanitation (clean water and pest
control). However, the incidence of vaccine-preventable diseases
began to drop dramatically after the vaccines for those diseases
licensed and began to be used in large numbers of children.
- For example, there were about
500,000 reported cases and 500 deaths from measles each year
before the measles vaccine was licensed in 1963.2
In 2002, only 44 cases were reported in the United States.3
- Since the Hib vaccine was
introduced in 1985, serious Hib disease has declined from about
20,000 cases per year to 34 cases in 2002.14
diseases decline before vaccinations began due to better sanitation
and clean water?
Better living conditions have been important in controlling some
kinds of infectious diseases, such as diseases spread by dirty water
and certainly better hygiene and sanitation has helped reduce the
spread of disease and mortality rate from many diseases.
However, it wasn’t until vaccines became available there was
significant change in the number of cases of diphtheria, tetanus,
pertussis, polio, measles, mumps, rubella, Hib, hepatitis B,
meningococcal disease, pneumococcal disease and chickenpox. Here are
a of couple examples:
- Measles vaccine was first approved in Canada in 1963 and
sanitation and living conditions in Canada have not changed
greatly since that time. Before the measles vaccine was
available, almost everyone got measles and for many children the
disease was serious: about 5,000 were hospitalized every year,
and 50 to 75 children died. It wasn’t until after the vaccine
was introduced that we started to see the number of measles
cases decrease dramatically. Because the vaccine is in wide use,
there are few cases of measles in all of North and South
America, including communities where living conditions are much
poorer than in Canada.
- Meningitis (infection around the brain) and other severe
infections due to Hib were common until just a few years ago. In
1985, before the first Hib vaccine was licensed, there were 485
invasive Hib cases reported. Case totals fell progressively as
better vaccines became available. In 2000, only four cases were
reported — 99% fewer than in 1985. Since the introduction of the
Hib vaccine the majority of pediatric cases occur in unimmunized
children or in children too young to have received their primary
series. Sanitation is no better now than it was in 1990, so it
is hard to credit anything but the widespread use of Hib vaccine
for this dramatic improvement.
Didn't diseases decline before vaccinations began
due to better sanitation and clean water?
NO. The diseases were just as prevalent
until widespread immunization began. What was changing was
the death rate from some of these infections.
That shouldn't be a big surprise; we know that improvements in
social and economic conditions mean a general improvement in health.
And thanks to cleaner drinking water and generally higher standards
of living, even though just as many people were getting sick, more
them were recovering (or at least not dying).
But once immunization started, the number of infections dropped
sharply — as did the severity of the illnesses of those who did get
Did you know? Until recently,
Haemophilus influenzae type b (Hib) was a leading cause of

Cette maladie sévit partout dans le monde. Les cas sont
sporadiques et relativement rares dans les pays industrialisés. Dans
bien des pays en développement, notamment en Asie, en Afrique et en
Amérique du Sud, la maladie demeure une importante cause de décès.
Épidémiologie du tétanos au Canada
Le tétanos est rare au Canada. Durant les années 1920 et 1930,
on enregistrait chaque année de 40 à 50 décès attribuables
au tétanos. Après l'introduction de l'anatoxine tétanique au
Canada, en 1940, la morbidité et la mortalité ont décliné
rapidement (voir la figure 1).
1980 à 2008, le nombre de cas signalés annuellement variait de 1
à 10, et la moyenne s'établissait à 4 par année. Durant cette
période, les personnes de ≥ 60 ans représentaient
des cas. Aucun cas n'a été répertorié chez les nouveau-nés. Le
statut vaccinal de la plupart des cas déclarés était inconnu. Cinq
décès seulement ont été déclarés depuis 1980, et le dernier est
survenu en 1997.
Au cours de la période de 7 ans visée par l'étude, 7 227
hospitalisations pour une méningite bactérienne ont été
recensées. Le nombre annuel d'hospitalisations variait de 1 072 à

variait entre 3,66 et 3,37 pour 100 000 habitants. Aucun changement

La méningite méningococcique est
présente partout dans le monde (500 000 cas par an selon l'OMS).
C'est la seule forme de méningite bactérienne qui provoque des
épidémies. Les souches A,B,C,Y et W135 sont à l'origine de 99 %
des cas de méningites cérébro-spinales. Le sérogroupe A est à
l'origine d'épidémies touchant de centaines de milliers de
personnes dans "la ceinture africaine de la méningite"

En France, en 2000, sur
les 497 cas recensés par le Centre National de Référence, 19 % des

Disorders among children exposed to thimerosal (5.95 per 1,000
8.27 per 1,000).
The research of Mark Geier, the main source of epidemiologic data
used by supporters of a link between thiomersal and autism, has
received considerable criticism, including charges of not presenting
methods and statistical analyses to others for verification,
improperly analyzing data taken from Vaccine Adverse Event Reporting
System, as well as either mislabelling or confusing

Of course the implications of this are profound. If there is no
autism epidemic, if there is a “stable incidence” of autism over
recent decades, then this alone is powerful evidence against the
vaccine hypothesis – and in fact removes the primary piece of
evidence for a vaccine-autism connection. Just as a true increase in
incidence would have called out for an environmental factor causing
autism, the lack of any increase argues strongly against any
environment factor – especially when this is combined with the
copious evidence for multiple genetic factors as the ultimate
cause(s) of ASD.
Main article: Thiomersal
In 1999, the Centers
Disease Control (CDC) and the American
of Pediatrics (AAP) asked vaccine makers to
remove the organomercury
(spelled "thimerosal" in the US) from vaccines as quickly
as possible, and thiomersal has been phased out of US and European
vaccines, except for some preparations of influenza
The CDC and the AAP followed the precautionary
principle, which assumes that there is no harm
exercising caution even if it later turns out to be unwarranted, but
their 1999 action sparked confusion and controversy that has

causal relationship between thiomersal-containing vaccines and
Autism incidence rates increased steadily even after thiomersal was
removed from childhood vaccines.
Currently there is no accepted scientific evidence that exposure to
thiomersal is a factor in causing autism.
Main article: MMR
In the UK, the MMR
vaccine was the subject of controversy after
publication in The
Lancet of a 1998 paper by Andrew
Wakefield and others, reporting a study of 12
mostly with autism
spectrum disorders with onset soon after
administration of the vaccine.
During a 1998 press conference, Wakefield suggested that giving
children the vaccines in three separate doses would be safer than a
single vaccination. This suggestion was not supported by the paper,
and several subsequent peer-reviewed studies have failed to show any
association between the vaccine and autism.
It later emerged that Wakefield had received funding from litigants
against vaccine manufacturers and that Wakefield had not informed
colleagues or medical authorities of his conflict
had this been known, publication in The Lancet would not
taken place in the way that it did.
Wakefield has been heavily criticized on scientific grounds and for
triggering a decline in vaccination rates
(vaccination rates in the UK dropped to 80% in the years following
as well as on ethical grounds for the way the research was
In 2004 the MMR-and-autism interpretation of the paper was formally
retracted by 10 of Wakefield's 12 co-authors,

have all concluded that there is no evidence of a link between the

lack of confidence in MMR has damaged public health, and that design

In 2009, The
Sunday Times reported that Wakefield had
manipulated patient data and misreported results in his 1998 paper,
creating the appearance of a link with autism.

which led to lower vaccination rates, putting hundreds of thousands
of children at risk and diverting energy and money away from
into the true cause of autism.
A special court convened in the United
States to review claims under the National
Vaccine Injury Compensation Program ruled on 12
February 2009 that parents of autistic children are not entitled to
compensation in their contention that certain vaccines caused autism
in their children.
Vaccine overload is the notion that giving many vaccines at once may
overwhelm or weaken a child's immature immune system and lead to
Although the scientific evidence strongly contradicts this idea,
some parents of autistic children believe that vaccine overload
The resulting controversy has caused many parents to delay or avoid
immunizing their children.
Such parental misperceptions are major obstacles towards
The concept of vaccine overload is flawed on several levels.
Despite the increase in the number of vaccines over recent decades,
improvements in vaccine design have reduced the immunologic load
vaccines; the total number of immunological components in the 14
vaccines administered to US children in 2009 is less than 10% of
it was in the 7 vaccines given in 1980.
A study published on 2013 found no correlation between autism and
number in the vaccines the children were administered up to the age
of two. Of the 1008 children in this study, a quarter of them were
diagnosed with autism were born between 1994 and 1999, when the
routine vaccine schedule could contain more than 3000 antigens (in a
single shot of DTP
vaccine). The vaccine schedule in 2012 contains
several more vaccines but the number of antigens the child is
to by the age of two is 315.
Vaccines pose a minuscule immunologic load compared to the pathogens
naturally encountered by a child in a typical year;
common childhood conditions such as fevers and middle-ear
infections pose a much greater challenge to the
system than vaccines,
and studies have shown that vaccinations, and even multiple
concurrent vaccinations, do not weaken the immune system
or compromise overall immunity.
The lack of evidence supporting the vaccine overload hypothesis,
combined with these findings directly contradicting it, have led to
the conclusion that currently recommended vaccine programs do not
"overload" or weaken the immune system.
Any experiment based on withholding vaccines from children has been
and observational studies would likely be confounded
by differences in health-care-seeking behaviours of under-vaccinated
children. Thus, no study directly comparing rates of autism in
vaccinated vs. un-vaccinated children has been done. However, the
concept of vaccine overload is biologically implausible, vaccinated
and unvaccinated children have the same immune response to
non-vaccine related infections, and autism is not an immune-mediated
disease, so claims that vaccines could cause it by overloading the
immune system goes against current knowledge of the pathogenesis
of autism. As such, the idea that vaccines cause autism has been
effectively dismissed by the weight of current evidence.
A 2011 journal article described the vaccine-autism connection as
"the most damaging medical hoax of the last 100 years".
There is evidence that schizophrenia
is associated with prenatal exposure to rubella,
infection. For example, one study found a sevenfold increased risk
schizophrenia when mothers were exposed to influenza in the first
trimester of gestation. This may have public health implications, as
strategies for preventing infection include vaccination,
and simple hygiene.
Based on studies in animal models, theoretical concerns have been
raised about a possible link between schizophrenia and maternal
immune response activated by virus antigens; a 2009 review concluded
that there was insufficient evidence to recommend routine use of
vaccine during the first trimester of
pregnancy, but that the vaccine was still recommended outside the
first trimester and in special circumstances such as pandemics or in
women with certain other conditions.
The CDC's Advisory
on Immunization Practices, the American
of Obstetricians and Gynecologists, and the
of Family Physicians all recommend routine flu
shots for pregnant women, for several reasons:
- Their risk for serious influenza-related medical complications
during the last two trimesters;
- Their greater rates for flu-related hospitalizations compared
to nonpregnant women;
- The possible transfer of maternal anti-influenza antibodies to
children, protecting the children from the flu; and
- Several studies that found no harm to pregnant women or their
children from the vaccinations.
Despite this recommendation,
only 16% of healthy pregnant US women surveyed in 2005 had been
vaccinated against the flu.

In some cases aluminum-containing vaccines are associated with
myofasciitis (MMF), localized microscopic lesions
containing aluminium salts that persist up to 8 years. However,
recent case-controlled studies have found no specific clinical

evidence that aluminium-containing vaccines are a serious health

Over the first six months of its life, an infant ingests more
aluminium from dietary sources such as breast milk and infant
than it does from vaccinations.
Other safety concerns
about vaccines have been published on the Internet, in informal
meetings, in books, and at symposia. These include hypotheses that
vaccination can cause sudden
death syndrome, epileptic
sclerosis, and autoimmune
diseases such as type
diabetes, as well as hypotheses that
can transmit bovine
virus, and HIV.

offered no possible cause for this correlation,
but held that the statistical evidence linking
vaccines and neurological disorders was strong.
Dr. Bill Weil, a consultant for the American
Academy of Pediatrics, and Dr. Richard Johnston,
an immunologist and pediatrician from the
University of Colorado, presented similar
concerns to the group. However, given no causal
relationship, the CDC and industry
representatives were quick to discredit the
- Consequently, the CDC paid the Institute of
Medicine (IOM) to conduct another study on thimerosal.
According to Robert F. Kennedy Jr., this study was fixed in
order to "whitewash" previous findings. In its 2001 report,
the IOM's Immunization Safety Review Committee did conclude
that the link between thimerosal and neurodevelopmental
disorders was biologically plausible, though the evidence
neither proved nor negated it. The Committee stated that
phasing out thimerosal from vaccines was "a prudent measure in
support of the public health goal to reduce mercury exposure
of infants and children as much as possible."
- However, these findings offered no
imperative. The data presented at the 2000 meeting was
withheld from publication and the link between thimerosal and
autism remained "inconclusive."
- While officials at the Center for Disease
Control claim evidence is lacking to support the possible
risks of thimerosal, Dr. Mark Geier, a Maryland geneticist and
vaccinologist, along with his son and research partner David
Geier, says the CDC has chosen to ignore the science.
According to Dr. Geier, more than 5,000 articles have been
published that question the safety of thimerosal in vaccines.
- The Geiers analyzed the data and determined
that the more thimerosal a child receives, the greater his or
her chances are of being autistic. The CDC says the Geiers
misused information from a CDC database that was not intended
to help prove theories. Given no real causal mechanism linking
thimerosal and autism, the game seems to have become one of
slanting the data to suit the needs of government and
industrial interests. Even Verstraeten has admitted that these
"inconclusive" findings certainly don't rule out the
possibility of finding a link in the future.
"We're going to continue to do the research to look for

unvaccinated children versus 13,359 vaccinated

number of unvaccinated children included in the
analysis is so small, statistical
evaluation is nearly impossible. However, the
study did show that unvaccinated human
children in two of the three age groups under
investigation showed fewer infections and atopic
disorders than those who were vaccinated, and
none of the unvaccinated children younger than
10 had developed asthma.
A growing number of scientists believe that the increase in
America, Europe, Australia and Japan in allergic and auto-immune
diseases (which stimulate the humoral or Th2 branch of the immune
system) is caused by the lack of stimulation of the cellular or the
Th1 branch of the immune system from the lack of acute inflammatory
responses and discharges in childhood. 2

identify the factors which cause this shift in the function of the
immune system or which cause allergies and auto-immune diseases in
childhood to increase!
If we now return to the original question of the mechanism of
action of vaccinations, we find what I believe is the key to the
puzzle. A vaccination consists of introducing a disease agent or
disease antigen into an individual’s body without
causing the disease. If the disease agent provoked the whole
immune system into action it would
cause all the symptoms of the disease! The symptoms of
disease are primarily the symptoms (fever, pain, malaise, loss
function) of the acute inflammatory response
to the disease.
So the trick
of a vaccination is to stimulate the immune system just enough so
that it makes antibodies and "remembers" the disease
antigen but not so much that it provokes an acute inflammatory
response by the cellular immune system and makes us sick with the
disease we’re trying to prevent! Thus a vaccination works by
stimulating very much the antibody
(Th2) and by stimulating very little or

Since 1988, Polio cases worldwide have decreased by

countries remain polio endemic, namely Afghanistan, India, Nigeria

- No one realizes that at the same time polio
cases began to wane, the first world was improving sewage and
water systems. I would liken the reduction in cases to
improved potent water supplies and to improved sewage
treatment. I remember in the early 1950's the city of Yonkers,
NY came to the suburb of Yonkers, Sherwood Park, east yonkers
and actually required us to hook up to the sewer system. At
that time our home was using a cess pool and well water. Many

- Polio is actually spread via feces/oral
route. I would wager that President Roosevelt got his polio
swimming in the Hudson river which is where many of my
neighbors got their polio. I remember seeing signs which read
"No Swimming due to Polio" in Alpine NJ along beaches on the
Hudson River. The Hudson was notorious for having raw sewage
- If polio vaccine is the sole reason for
ending the spread of polio in the first world, then why
hasn't polio ended in India, the Congo and other
countries? There have been countless polio vaccine
campaigns year after year in Africa, India etc yet we keep
hearing about outbreaks, currently, India and Africa have
polio outbreaks. The answer is not vaccine but sanitation. In countries that have raw sewage entering the
rivers, lakes etc where people use these same waterways for
drinking and cooking the disease will never die away. The
money spent on vaccine is only a fraction of what it would
cost to put in decent sanitation which would include sewers
and sewage treatment along with providing potable safe
drinking water in the third world, so, consequently, the
pharma industry with a lot to lose talks about the reduction
of polio via vaccine. Ergo, the myth is perpertrated.
Do you know how much doctors learn about vaccines in
medical school? When we participate in pediatrics training, we learn
that vaccines need to be given on schedule. We learn that
smallpox and polio were eliminated by vaccines. We learn that
there’s no need to know how to treat diphtheria, because we won’t
see it again anyway. We are indoctrinated with the mantra that
“vaccines are safe and effective” – neither of which is true.
Doctors today are given extensive training on how to
talk to “hesitant” parents – how to frighten them by vastly
inflating the risks during natural infection. They are trained
on the necessity of twisting parents’ arms to conform, or fire them
from their practices. Doctors are trained that NOTHING bad
should be said about any vaccine, period.
The global eradication of poliomyelitis is a public
health effort to eliminate all cases of poliomyelitis
(polio) infection around the world. The global effort, begun in 1988
and led by the World
Organization (WHO), UNICEF
and the Rotary
Foundation, has reduced the number of annual diagnosed
cases from the hundreds of thousands to 291 in 2012 - a 99.9%
reduction. Of the 3 types of polio, the last recorded wild case of
type 2 was in 1999. The last recorded case of type 3 was on 11
November 2012. All reported cases since 11 November 2012 have been
type 1. If polio is the next disease to be successfully eradicated,
this will represent only the third time this has ever been achieved,
The goal of eradicating worldwide polio has attracted international
and media attention, but since 2001 progress has been erratic in
reducing the number of cases, which has led to getting rid of the
last 1% being described as "like trying to squeeze Jell-O
However, in 2011 incidence rates of the disease were dramatically
reduced, and with large reduction again in 2012, hopes for
eliminating polio have been rekindled. India
is the latest country to successfully stop transmission of polio.
Because there is no long term carrier
state for poliovirus in immunocompetent
individuals, polioviruses have no non-primate reservoir in nature,
and survival of the virus in the environment for an extended period
of time appears to be remote. Therefore, interruption of person to
person transmission of the virus by vaccination is the critical step
in global polio
The two vaccines have eradicated polio from most countries in the
and reduced the worldwide incidence from an estimated 350,000 cases
in 1988 to just 223 cases in 2012.

britannique Andrew Wakefield, la recherche en question, publiée en
1998, affirmait avoir trouvé des traces du virus de la rougeole

intestinales réalisées auprès de huit enfants autistes.
Aussitôt publiés, ces résultats ont suscité un véritable vent
de panique dans le monde anglo-saxon. Les taux de vaccination ont
chuté radicalement, à 81% en Angleterre et à 76% en Irlande. Alors
que, en 1999, seules 148 personnes ont eu la rougeole en Irlande, en
