WASHINGTON - A bill that marshals
an army of new research dollars to strike a forceful blow against
autism deserves - and we hope will get - full consideration from
the House of Representatives when it returns in September.
Passed unanimously by the Senate
on Aug. 3, the Combating Autism Act will increase research funds
for autism and offers new hope that a cure can be found for the
nation's most common genetic disorder.
The bipartisan act would bolster
an already strong base of existing science about the origins of
autism. Medical researchers believe it could lead to breakthroughs
that might eventually help cure a disease that affects a growing
number of children and their families.
Equally important, the bill could
finally lay to rest an unfounded theory propounded by a small
group of physicians and parents, who claim a link between autism
and the thimerosal preservative contained in many vaccines.
advertisement Recently, five
recent major studies examining the health records of hundreds
of thousands of children in the United States, Britain, Denmark,
Sweden and Canada found no link between autism and vaccines or
thimerosal. The peer-reviewed studies - published in prestigious
medical journals - show that the rates of autism either remained
the same or increased after mercury-containing thimerosal was
removed from childhood vaccines.
Unfortunately, misplaced media
attention to this nonexistent link obscures the very real issues
surrounding autism and shifts attention away from what is genuinely
needed: federal funding for increased research into the disorder,
advanced training for medical professionals, increased early diagnosis
and improved services for autistic children and their parents.
Given that autistic spectrum
disorders are among the most common genetic conditions - occurring
in one of every 166 live births - we should not waste any more
time pursing what amounts to a dead-end speculation.
The Combating Autism Act would,
among other things:
• Double the amount that
the National Institutes of Health spends on autism research.
• Create a screening program
in all 50 states for the early identification of children with
autism.
• Fund the efforts of the
Autism Treatment Network to identify the best medical practices
in the treatment of autistic kids.
• Continue funding of the
epidemiological and public education programs on autism at the
Centers for Disease Control and Preven- tion.
The bill, which would authorize
nearly $1 billion over the next five years to conduct a variety
of activities to fight the disease, is long overdue and deserves
swift passage.
At present, research about autism
is lim- ited.
We do know it is a genetic disorder
associated with structural changes in the brain that begin prior
to birth. We also know that autism genes produce effects that
lead to an excessive increase in head size at about one month
of age, well before a baby receives its first set of pediatric
vaccines. And we know heredity is the most important risk factor
for these structural changes in autistic brains.
A stepped-up effort to fund such
research could lead to the development of new treatments, genetic
screening tools and an evidence-based program of genetic counseling.
The Combating Autism Act is,
indeed, an act of enlightenment. In addition to helping us to
understand the root causes of autism, it should undercut those
who inaccurately blame lifesaving vaccines for the disorder.
That mistaken belief, if perpetuated,
could create a public health crisis that will make urgently needed
vaccines unavailable to our children. Already, there have been
widespread demands by state legislatures to limit the use of vaccines
in children or to change their mode of production.
In California, for instance,
soon children will no longer be allowed to receive the influenza
vaccine - a ban that could trigger an epidemic in the nation's
most populous state. Reduced immunization rates will substantially
reverse public health gains made over the last four decades and
lead to unnecessary childhood deaths.
In the meantime, it is important
to remember that today's vaccines save lives. Some estimates indicate
that the global use of childhood vaccines for diphtheria, pertussis,
tetanus, measles, mumps, rubella, Haemophilus influenzae meningitis
and polio have saved 160 million lives over the last 25 years.
That number is equivalent to all of the lives lost in all world
wars during the 20th century.
By passing the Combating Autism
Act this year, Congress can help millions of American families
- both those who are affected by autism and those who will continue
to have access to vaccines that protect their children from many
other preventable diseases.

GUEST VIEWPOINT
Don't just dismiss the vaccine-autism
link
By Bobbie Manning
and Robert Krakow
Published:

In their Aug. 18 editorial page
column "Act could turn the tide on common birth defect,"
Peter Hotez and Rosalynn Carter anticipate the Combating Autism
Act's promise in disproving the role of vaccines in causing autism.
As Boyd Haley, professor of chemistry of the University of Kentucky
has commented, "The article is totally devoid of any scientific
credibility."
Hotez and Carter reveal the poisonous
agenda of those who would use government funds to bury the inconvenient
theory that mercury in vaccines has caused the autism epidemic.
Their main interest is to develop and promote vaccines.
It is troubling that anyone would
advocate using public money to improperly influence research of
a threatening hypothesis. The purpose of the Combating Autism
Act should be to find the causes of and treatments for autism,
not protect the vaccine program.
The authors misleadingly claim
the thimerosal-autism link has been disproved. The U.S. study
that inadequately examined this issue failed to make clear comparisons
between children receiving thimerosal and those receiving none.
Its lead author concluded that "an association between thimerosal
and neurological outcomes could neither be confirmed nor refuted,
and therefore, more study is required."
The Institute of Medicine has
reported limitations in the studies on which the authors rely,
and concluded in a vaccine safety report that the hypothesis that
thimerosal causes autism cannot be excluded for a subset of genetically
susceptible individuals. The directors of the National In- stitutes
of Health and the Centers for Disease Control have testified in
Congress in accord with the IOM assessment.
Hotez and Carter misrepresent
research by claiming that "autism genes produce effects that
lead to an excessive increase in head size at about one month
of age, well before a baby receives its first set of pediatric
vaccines." Yet thimerosal-containing Hepatitis B vaccine,
RhoGam, and flu shots given to pregnant women all result in prenatal
or newborn exposures to children.
Contrary to the authors' claim
that autism is a "genetic disorder," genetics alone
cannot explain autism. Recent research confirms that autism develops
in many cases after 18 months of age. In most cases, children
are not born with autism; science points to complex genetic susceptibilities
triggered by environmental toxins.
The leading researcher on enlarged
head size in autism has stated that environment plays a role.
Increased head size occurs postnatally when provoked by toxic
exposures. Prenatal exposure to drugs can cause autism. Concordance
of autism among identical twins is incomplete.
The claim that the thimerosal
theory has caused vaccine shortages is baseless fear-mongering.
Prior to 2004, infants were rarely given the flu vaccine - yet
there was then no flu epidemic or hysteria about vaccine shortages.
Vaccine manufacturers can produce the ample supplies of thimerosal-free
vaccines. The claimed suppression of vaccination rates never happened;
despite widespread media reports of the autism-thimerosal link,
vaccination rates are at historical highs in the U.S.
A 2003 congressional report concluded
that thimerosal did pose a risk and was related to the epidemic
of autism. The report stated that the epidemic might have been
prevented "had the FDA not been asleep at the switch regarding
the lack of safety data regarding injected thimerosal and the
sharp rise of infant exposure to this known neurotoxin. Our public
health agencies' failure to act is indicative of institutional
malfeasance for self-protection and misplaced protectionism of
the pharmaceutical industry."
Hotez's and Carter's suggestion
that the Combating Autism Act can serve to refute the thimerosal
theory casts suspicion on the intent of those who would implement
the act. The act should not be used as a bludgeon to beat back
a theory that threatens vested interests. Rather, the act should
promote honest, unbiased and conflict-free science. If research
funded by the bill is to be used improperly, as the authors suggest,
the bill should die an ignominious death.
On the other hand, if research
funded by the act is insulated from bias, honest answers regarding
autism's cause might be obtained. We must eschew an agenda aimed
at covering up another "inconvenient truth."
Our children deserve a bill aimed
squarely at combating autism, not one pretending to do so by countering
one uncomfortable theory about autism. If the bill becomes law,
let oversight be vigilant, let honest research flow, let the chips
fall where they may.
