In the article, "Mercury, Vaccines, and Autism: One Controversy, Three
Histories" the author, while trying to sound impartial, misrepresents
several facts in order to support his conclusions. He starts by citing
the many findings of the Institute of Medicine (IOM) without mentioning
that the IOM was commissioned by the CDC to issue a report on "Vaccines
and Autism." The CDC approves, mandates, promotes, and distributes
vaccines. He does not mention that every member of the IOM committee had
ties to the vaccine program (1). There were no independent toxicologists
on this committee. One would think this would be important when
considering the safety of mercury in vaccines.
The author cites the inventors of thimerosal and writes, "extensive in
vitro testing shows that thimerosal was 40 to 50 times as effective as
phenol against Staphylococcus aureus." He then claims "concerns over
neurotoxicity in infants receiving thimerosal from vaccines were never
raised by medical or government authorities before the late 1990s." This
is false. In 1982, an independent panel was convened by the FDA (2). The
panel called for the removal of mercury, including thimerosal, from all
over-the-counter products. It declared thimerosal as being both unsafe and
ineffective. It was singled out as being "no better than water in
protecting mice from fatal streptococcal infection." It was shown to be
35.5 times more toxic to embryonic chicken heart tissue than the
aforementioned Staphylococcus aureus.
He goes on to declare that the "comparatively miniscule exposures [of
thimerosal] involved in vaccines were well within all published guidelines
for mercury exposure." Unfortunately, he never took the time to analyze a
vaccine vial for mercury concentration. The Hepatitis B vaccine,
administered at birth for over ten years, contained 25,000 parts per
billion (ppb) of mercury in the multi-dose vaccine vial. The multi-dose
DTP and Haemophilus B vaccine vials, administered 4 times each in the
1990s to children at 2, 4, 6, 12 and 18 months of age, contained 50,000
ppb mercury. According to the EPA, any liquid that contains more than 200
ppb mercury is to be classified as hazardous waste based on toxicity (3).
It's hard to believe that a level of mercury 250 times higher than
hazardous waste levels would be referred to as "miniscule." The fact is,
on any given day of receiving even a single thimerosal containing vaccine
in the 1990s, all published guidelines for mercury exposure were
exceeded.
Several pages of the paper examine the toxicity of methylmercury and
its past use as a fungicide. We are led to believe that this form of
mercury is much different than ethylmercury, the type found in vaccines.
This is in spite of the fact that ethylmercury was used for the same
purpose. In fact, Ethylmercurric Chloride, the material used as a fungicide
(which was banned long ago) is what is used to make thimerosal. This can
be easily confirmed by looking in a Merck Index. We now know that this
type of mercury deposits twice as much inorganic mercury in the brains of
primates as compared to equal doses of methylmercury (4). Inorganic
mercury, following the de-methylation of organic mercury, has been
identified as the primary neurotoxic agent in primate studies (5).
The author mentions the book, "Evidence of Harm: Mercury in Vaccines
and the Autism Epidemic" by David Kirby. It contains 436 scientific
references. The author did not disclose if he read the book. This may have
helped his argument since this book was read by many parents of autistic
children.
We are then told about the impact of trial lawyers concerning this
situation. The author does not disclose how much money has been awarded to
trial lawyers who represent autistic children. It's my understanding that
this number is zero.
