Right. And even the CDC has only said that the government's studies "favor rejection of mercury as a causal agent of autism"- NOT that it has been proven that mercury doesn't cause autism.
The Age of Autism: Mercury ascending

WASHINGTON, May 17 (UPI) -- A year ago, the prestigious Institute of
Medicine slammed the door on the idea that mercury in vaccines bore
any relation to autism.
"The overwhelming evidence from several well-designed studies
indicates that childhood vaccines are not associated with autism,"
the chairman of the IOM panel, Harvard scientist Marie McCormick,
told reporters last May 18.
The panel went further: It took the unusual step of urging that
research money go instead to more "promising" areas. You can't slam a
door much harder than that.
But 12 months later, that door seems slightly ajar. One big doorstop
is the new 441-page book by David Kirby called "Evidence of Harm," a
compelling portrayal of parents and scientists who have pushed the
vaccines-autism theory. They contend that a mercury-based
preservative called thimerosal, in an increasing number of
vaccinations, triggered an autism epidemic in the 1990s.
Thimerosal was phased out of U.S. childhood vaccines beginning in
1999.
One memorable vignette in Kirby's book is a meeting between several
of those advocates and Dr. Julie Gerberding, who had been director of
the Centers for Disease Control and Prevention less than two years.
Last May 12, a week before the IOM report, Gerberding flew in from
Atlanta to meet them -- at her request -- in the Rayburn House Office
Building on Capitol Hill. Rep. Dave Weldon, R-Fla., a medical doctor
who is a persistent critic of thimerosal and the CDC's handling of
the issue, also was present.
Taking turns, the parents and scientists methodically laid out their
case.
Mady Hornig of Columbia University described how mice with an
autoimmune genetic predisposition develop autistic-like behaviors
after being injected with thimerosal-containing vaccines.
"Hornig played the videos for Gerberding, who suddenly appeared
stunned," Kirby recounts in his book. "She brought her hands to her
face in disbelief.
"Dave Weldon had a similar reaction. He stopped Hornig in the middle
of her ghastly presentation. 'Wait a minute,' he said. 'Am I to
understand you correctly? You injected these mice with the same
amount of mercury, relatively speaking, that infants receive in
vaccines, and you saw these kinds of mutilatory behaviors? You saw
this mouse eat through the cranium of his cellmate?'
"'Yes,' she replied calmly."
The Institute of Medicine saw the same presentation before issuing
its report but rejected it as unconvincing.
Gerberding was polite but noncommital, Kirby writes. As she left,
she said, "I am not afraid of controversy, and I am determined to
follow the science."
Call it coincidence, but it's striking how much less dismissive of
thimerosal concerns the CDC is these days, compared with the
Institute of Medicine and others.
The National Network for Immunization Information, for instance,
launched a pre-emptive broadside against "Evidence of Harm." That
group represents the mainstream medical establishment, including the
American Academy of Pediatrics, the American Nurses Association and
the American Academy of Family Physicians. Their members, it should
be noted, were among those who administered the vaccines in question
on the recommendation of the CDC.
"Warning: Controversial vaccine book," the NNII statement was
headlined. "Reporter David Kirby has recently written a book ...
purporting that there is a link between thimerosal and autism and
other developmental disorders."
That's a bit of an overstatement, considering the first two
sentences of Kirby's book: "Does mercury in vaccines cause autism in
children? Anyone hoping to find proof that it does in the pages that
follow is advised to put this book down now."
The NNII asserted that "extensive evidence shows no link between
vaccines and neurodevelopmental disorders, including autism. This
evidence is based on well-established scientific studies.
"Continued attempts to link vaccines and autism run the risk of
diverting attention away from efforts to understand the cause or
causes of autism," the group said.
The CDC also issued a release on Kirby's book. Its thrust was
different -- that the book is a "look back" to a time when thimerosal
was in childhood vaccines.
"Given the historical nature of the book, it is important to
emphasize that today, with the exception of some flu vaccines, none
of the vaccines used in the U.S. to protect preschool children
against 12 infectious diseases contain thimerosal as a preservative.
"As the IOM concluded in a recent report, the vast majority of
studies, which have involved hundreds of thousands of children in a
number of countries, have failed to find any association between
exposure to thimerosal in vaccines and autism; that is, they have
failed to find any evidence of harm," the CDC said.
It's worth noting the contrasts in the statement. The doctors and
nurses group says "extensive evidence shows no link." Dr. McCormick
at the Institute of Medicine says "overwhelming evidence" shows no
link.
But the CDC, which unlike such groups has ongoing access to the
actual data, merely states that studies so far "have failed to find
any association."
"CDC continues to support research related to autism," the statement
said, "including studies designed to examine the possible causal
association between autism and other possible environmental causes,
including thimerosal-containing vaccines. ... Research in these areas
is ongoing."
Ongoing research that includes thimerosal as a possible cause of
autism? Supported by the CDC?
Put simply, the CDC isn't ruling out anything -- contrary to the
Institute of Medicine's declaration that more research on thimerosal
is a waste of money, contrary to the medical establishment's
pronouncement that continuing to look could cause harm.
Consider Gerberding's comments April 28, 2004, at a House
subcommittee hearing: "We don't have the evidence to show that the
thimerosal preservative is a risk, but you know we have an open mind
about that."
