Two new studies offer evidence that vaccinated children have more health problems than unvaccinated children
Among
unvaccinated premature infants, no link to neurodevelopmental disorders
(NDD) was found. However, a significant link between vaccinations and
NDD was detected, regardless of whether the child was premature or
full-term
The
combination of preterm birth with vaccination was associated with a 660
percent increased odds of NDD, suggesting a synergistic effect
By Dr. Mercola
When it comes to vaccine safety, a complaint that I've frequently
expressed is the lack of credible studies comparing vaccinated and
unvaccinated populations.
At best, we've had vaccination surveys1 based on self-reported data,2
and while that evidence strongly suggested unvaccinated children
experience better health and fewer health problems, they were dismissed
by most public health officials as unimportant. There are also
published studies showing annual influenza vaccination takes its toll on your health, 3,4,5,6 and may do more harm than good in the long term.
Now, two pilot studies led by Anthony Mawson,7
an interdisciplinary epidemiologist and social scientist with a
doctorate in public health, have helped to shed some light on the
topic.
The gold standard in scientific research is replication and, while
the conclusions of these studies need to be replicated using other data
sources, they are another piece of evidence showing there are negative
health outcomes for vaccinated children, and that unvaccinated
children are actually healthier. It's a good start, and it's important
to know these studies exist.
Vaccination Schedule May Place Preemies at Increased Risk of Neurodevelopmental Disorders
The first paper,8
published in the peer-reviewed open-access Journal of Translational
Science April 24, 2017, is a cross-sectional study of 6- to
12-year-olds exploring the association between preterm birth,
vaccination and neurodevelopmental disorders, using data from both
vaccinated and unvaccinated populations. Preemies receive the same
vaccines and number of doses recommended by the federal childhood
vaccination schedule as full-term babies, and on the same time schedule.
Data show anywhere from 8 to 27 percent of extremely preterm infants
develop autism spectrum disorder (ASD). Premature birth is a known risk
factor for neurodevelopmental problems of varying severity, yet prior
to this study, the impact of the vaccination schedule on this risk had
never been assessed. Not surprisingly, the results suggest the
federally recommended childhood vaccination schedule may be
inappropriate for premature infants. The abstract reads, in part:
"The possible role of vaccination in neurodevelopmental disorders
(NDD) among premature infants is unknown, in part because pre-licensure
clinical trials of pediatric vaccines have excluded ex-preterm
infants.
This paper explores the association between preterm birth,
vaccination and NDD, based on a secondary analysis of data from an
anonymous survey of mothers, comparing the birth history and health
outcomes of vaccinated and unvaccinated homeschool children 6 to 12
years of age.
A convenience sample of 666 children was obtained, of which 261 (39
percent) were unvaccinated, 7.5 percent had an NDD … and 7.7 percent
were born preterm. No association was found between preterm birth and
NDD in the absence of vaccination …
However, vaccination coupled with preterm birth was associated with
increasing odds of NDD, ranging from 5.4 [percent] compared to
vaccinated but non-preterm children, to 14.5 [percent] compared to
children who were neither preterm nor vaccinated.
The results of this pilot study suggest clues to the epidemiology
and causation of NDD but question the safety of current vaccination
practices for preterm infants. Further research is needed to validate
and investigate these associations in order to optimize the impact of
vaccines on children's health."
Vaccination Linked to Higher Risk of NDD Among Full-Term Babies Too
The fact that no link was found between premature birth and NDDs
among the unvaccinated raises the disturbing possibility that the
vaccination schedule for premature babies could be responsible for the
neurological disorders some premature babies exhibit, which have been
previously assumed to be simply a result of premature birth.
This provocative possibility is further strengthened by the finding
that vaccination was, in fact, linked with a higher risk of NDD among
full-term children. As noted in the paper, aside from preemies being
excluded from pre-licensure vaccine trials, another reason this issue
has never been formally investigated is "the assumed overall safety of
vaccinations." The results reveal why assuming safety uses seriously
flawed logic.
Another powerful example of why safety should never be assumed are
West African studies that revealed a high titer measles vaccine
interacted with the diphtheria-tetanus-pertussis (DTP) vaccine and
resulted in a 33 percent increase in infant mortality.9
Those shocking findings led to the withdrawal of that measles vaccine.
But what would have happened had those studies never been done?
Clearly, we need more like them.
The fact is, all vaccines need to be carefully evaluated not only
individually for long-term safety, but also for synergistic toxicity
when the vaccine is given in combination with other vaccines and given
repeatedly over a period of time. In 2013, a physician committee at the
Institute of Medicine (IOM), National Academy of Sciences, pointed out
that the current federally recommended childhood vaccine schedule for
infants and children from birth to age 6 had not been adequately
studied for safety.10
The physicians and IOM staff only were able to identify fewer than
40 studies published in the previous 10 years that addressed the 0 to
6-year-old child vaccine schedule.
The IOM committee concluded there was not enough scientific evidence
to determine whether or not the numbers of doses and timing of
federally recommended vaccines children receive in the first six years
of life are associated with health problems in premature infants or the
development of chronic brain and immune system disorders that affect a
child's intellectual development, learning, attention, communication
and behavior, such as ADD/ADHD, learning disabilities and autism.
This is why Mawson's pilot studies have great value and why many
more studies comparing the health of vaccinated and unvaccinated
children must be conducted. As noted by the IOM's11 2013 "Childhood Immunization Schedule and Safety" report, studies are needed to examine the:
Long-term cumulative effects of vaccines
Timing of vaccination in relation to the age and health of the child
Effects of the total load or number of vaccines given at one time
Effect of vaccine ingredients in relation to health outcomes
Biological mechanisms of vaccine-associated injury
It's also important for people to understand that the Vaccine Safety
Datalink (VSD) database, which the U.S. Centers for Disease Control
and Prevention (CDC) uses to publish studies concluding that vaccine
risks are negligible or nonexistent, is a closed database.12
The patient medical records data in the VSD is obtained from HMOs
that are paid by the CDC to participate. VSD medical records data is
not readily available to researchers, if at all, making the CDC's
conclusions virtually impossible to replicate and verify. This simply
isn't right because it prevents independent confirmation of the CDC's
conclusions that vaccine risks are minimal and the government's early
childhood vaccine schedule is safe, thereby contributing to the poor
evidence base for or against vaccine safety.
Summary of Findings
The authors of the recently published study on premature birth,
vaccination and neurodevelopmental disorders summarize their findings
as follows:
Preterm birth without vaccination was not associated with NDD
Term birth with vaccination was associated with a 2.7-fold (270 percent) increase in the odds of NDD
Preterm birth with vaccination was associated with a 5.4-fold
increase in the odds of NDD compared to the odds of NDD given term
birth and vaccination
Preterm birth with vaccination was associated with a 12.3-fold
increased odds of NDD compared to preterm birth without vaccination
(not technically significant because no child in the sample with an NDD
was both preterm and unvaccinated)
Preterm birth with vaccination was associated with a 14.5-fold
increased odds of NDD compared to being neither preterm nor vaccinated
In adjusted regression analyses, the association between vaccination
and NDD remained even after taking other contributing factors into
account. In the final adjusted model, the combination of preterm birth
with vaccination was associated with a 660 percent increased odds of
NDD, "suggesting a synergistic effect." How do the authors explain
these findings? A "tentative hypothesis" for why preemies are at
increased risk for NDD was associated with receipt of one or more
vaccines. The authors concluded:
"Receipt of one or more vaccines could precipitate NDD in some
preterm infants by exacerbating a preexisting inflammatory state
associated with prematurity, leading to hepatic encephalopathy and
hypoxic-ischemic brain damage. Impaired liver function is a
predisposing factor for preterm birth and the latter is associated with
increased risks of hypoxic-ischemic brain injury …
Consistent with this hypothesis, liver dysfunction is reported
as an adverse effect of vaccination and as a feature of children with
autism. Furthermore, hyperbilirubinemia is associated with
hypoxic-ischemic brain damage and is a feature of the preterm infant as
well as children with later-onset cognitive disorders and ASD."
Pilot Study Compares Health of Vaccinated and Unvaccinated Children
The second paper,13
published on the same issue of the journal, was a pilot study "designed
as a cross-sectional survey of homeschooling mothers on their
vaccinated and unvaccinated biological children ages 6 to 12," in which
a wider range of health outcomes was evaluated. The results showed
vaccinated children were:
"[S]ignificantly more likely to have been diagnosed with
pneumonia, otitis media, allergies and NDD (that is, ASD, ADHD and/or a
learning disability). The vaccinated were also more likely to use
allergy medication, to have had myringotomies with tube placement,
visited a doctor for a health problem in the previous year, and been
hospitalized at some time in the past."
More specifically, the results showed vaccinated children (whether
partially or fully vaccinated) were significantly more likely than the
unvaccinated to have been diagnosed with:
Otitis media (19.8 percent versus 5.8 percent)
Pneumonia (6.4 percent versus 1.2 percent
Allergic rhinitis (10.4 percent versus 0.4 percent) as well as other allergies (22.2 percent versus 6.9 percent)
Eczema/ atopic dermatitis (9.5 percent versus 3.6 percent)
Any chronic illness (44 percent versus 25 percent)
IOM's Vaccine Safety Review Is Still of Massive Importance
This is a perfect time to mention the IOM's vaccine safety review, "Adverse Effects of Vaccines: Evidence and Causality,"14
published in August 2011. Along with other reports the IOM has
published on vaccine safety issues beginning in 1991, it is one of the
most important scientific reviews of evidence in the medical literature
that vaccines can cause injury and death.
The National Academy of Sciences (NAS) through the IOM (recently
renamed Health and Medicine Division) historically has analyzed health
policies and issued reports at the request of the U.S. government.
Considered worldwide to be a prestigious scientific body, the NAS is
funded not just by federal agencies, but also by pharmaceutical
companies and independent philanthropic organizations and individuals.
Although vaccine safety advocates have criticized the IOM's reports
as being too conservative and minimizing the full extent of vaccine
risks, no other recognized scientific authority has so clearly
acknowledged that vaccines do cause harm, especially for susceptible
individuals, and that there are large vaccine science knowledge gaps
about safety that need to be addressed.
The first IOM reports on vaccine safety came out in 1991 (pertussis and rubella vaccines)15 and 1994 (DPT, polio, tetanus, diphtheria, measles, mumps, HIB and hepatitis B vaccines).16,17
However, the IOM's 2011 review of recent medical literature was
significant because it was quite comprehensive. Over a period of three
years, a physician committee reviewed over 1,000 vaccine studies
related to safety issues. Interestingly, and importantly, they excluded
studies funded by the pharmaceutical industry. The IOM review focused
on eight vaccines:
Hepatitis A-hepatitis B
Measles, mumps and rubella vaccine
Meningococcal vaccine
Pneumococcal vaccine
Diphtheria, tetanus and acellular pertussis, also known as DTaP or Tdap
Varicella zoster (chickenpox)
HPV vaccine
Influenza vaccine
Shocking Conclusion: IOM Unable to Make Causation Conclusions for Most Vaccine-Related Adverse Health Outcomes
Perhaps the most important thing the IOM did in this review was that they looked at two categories of science:
Epidemiological research (large studies comparing the health outcomes of different groups of people)
Bench science (basic science research into the biological mechanisms at work in the body at the cellular and molecular level)
This is important because many of the studies the CDC relies on as
evidence that vaccines don't cause any problems are epidemiological
studies and, if poor methodology is used, the conclusions of
epidemiological studies can be fatally flawed. In the 2011 review, the
IOM committee reviewed both kinds of science.
The most shocking conclusion of this report is that, for more than
100 adverse health outcomes reported after the eight vaccines were
given, the IOM committee was unable to determine whether or not the
vaccines caused a commonly reported brain or immune system disorder.
In short: The scientific evidence was insufficient to make a
conclusion in most cases. So the committee was unable to confirm or
deny causation for most reported poor health outcomes following receipt
of certain vaccines, such as multiple sclerosis, lupus and autism.
IOM Did Not Exonerate Vaccines as Being Safe for Everyone
Why was the IOM unable to determine whether there was a direct
causative link between vaccines and the many serious health outcomes
evaluated in these studies? Barbara Loe Fisher, founder of the National
Vaccine Information Center, www.NVIC.org,
which is, unquestionably, the best resource for accessing referenced
information on U.S. vaccine policy and law and the safety and
effectiveness of vaccines, suggested four possible explanations:
The studies were not available in the published literature
There were too few studies showing the same link
The available studies were methodologically unsound
The available studies were conflicting (i.e., there was evidence both for and against)
In the video above, I interview Fisher about this important IOM report. At the time, Fisher stated:
"What I call this category is the 'We Don't Know' category. When
you think about it, these vaccines are mandated for children, and yet
in most instances the scientific evidence [of safety] is so poor, they
don't know!
When the report came out, there were a lot of organizations like
the American Academy of Pediatrics that came forth and said, 'They
didn't find causation … so vaccines are safe.' That's NOT what that
report said at all. I think people need to understand the significance
of it … [T]he category of 'We Don't Know' is a very important
category."
IOM Proposed Individual Susceptibility May Be a Cofactor
Importantly, the IOM report also discussed individual susceptibility:
the fact that some people are more vulnerable to suffering vaccine
reactions and injury for biological, genetic and environmental reasons.
According to the report, both epidemiologic and biological mechanism
research suggests that many individuals who experience an adverse
reaction to vaccines have a preexisting susceptibility. However, the
report also states that in most cases physicians DO NOT KNOW what those
individual susceptibilities are and cannot predict ahead of time who
will be harmed by vaccination.
That said, the physician committee conducting the 2011 IOM medical
literature review listed some individual susceptibilities they believe
may be important, including:
Genetic variation
Age
Coinciding illness
Environmental factors
It's a 600-page report, so it's not light reading by any means.
Still, every physician who administers vaccines really should read it.
It's part of their responsibility to be informed about what's in the
published medical literature. This report makes it clear that when a
patient's health deteriorates after vaccination, you cannot simply brush
it off as a coincidence.
Doctors have a responsibility to take each instance of a health problem
that follows vaccination seriously, especially emergency room visits,
hospitalizations, injuries and deaths, and file a report with the
federal Vaccine Adverse Event Reporting System (VAERS).
When an individual experiences a deterioration in health after
vaccination, doctors also need to understand the danger of giving more
vaccinations until or unless the vaccine can be conclusively exonerated
as a causative or contributing factor to that health deterioration.
And guess what? For over 100 adverse events, science says they do not
know whether the vaccine might be a causative factor.
What this tells us is that physicians — or anyone — recommending and
administering vaccines to people, particularly to vulnerable infants
and children, need to apply the precautionary principle of "first do no
harm." This is critically important when the foundation of science
supporting the safety of any given vaccine, alone or in combination, for
any given individual is so weak.
