TAMPA -- Last month, for the first time, the national Centers for Disease
Control and Prevention encouraged parents to have their young children
vaccinated against the flu.
To most, it seemed a sound idea for protecting youngsters. But a vocal
minority of parents and doctors think such a move could be trouble.
The issue: Some flu vaccines still contain the mercury-based preservative
thimerosal, which they think is linked to an explosion in the number of children
diagnosed with autism and related disorders in the past two decades.
The many skeptics of this theory point out that the mercury used in
thimerosal has not been definitively linked to autism.
But those who think there is a connection see the CDC encouragement as a risk
for children, especially those who already might have a buildup of mercury in
their systems.
"They continue to promote thimerosal as safe mercury and that there is no
evidence of toxicity," said Dr. Jeff Bradstreet, an autism researcher in Palm
Bay and the father of an autistic boy. "Eventually, they will be proven wrong.
But in the meantime, one wonders how many lives may be altered."
Until last month, the CDC never had encouraged regular flu shots for healthy
children six months to 23 months old.
But about 20 children per 10,000 in that age group are hospitalized each year
with the flu or its complications. That rate is at least five times higher than
that of 5 to 15 year olds and 10 times higher than the rate for low-risk adults,
according to the CDC.
Young children also are effective carriers of the influenza virus, often
passing it on to relatives and friends. The CDC said vaccinating children would
help improve the societal armor and cut down on the number of adults who get the
flu.
The CDC is only encouraging parents to vaccinate their young children, not
recommending it. But a formal recommendation could come as early as next year.
Dr. Scott Harper, an infectious disease specialist with the CDC in Atlanta,
said the risks of complications from flu shots for young children are minimal,
especially when compared with the benefits.
"In every decision that we make in life, there is a risk and a benefit,"
Harper said. "This decision was based on facts, facts that show that many
children will avoid getting sick, not unproven theories."
Other health care giants -- including the U.S. Food and Drug Administration,
the National Institutes of Health, the American Academy of Pediatrics and the
National Network for Immunization Information -- also are skeptical of a link
between vaccines and autism. They say the theory is based more on coincidence
and hope than hard data.
Even the Autism Society of America isn't convinced.
"(We) strongly support research to determine if, in fact, there is a
correlation," the society says. "Until that research is performed and
replicated, vaccines continue to be indicated."

Thimerosal has been used as a preservative in vaccines since the 1930s, but
it became more common in the past 15 years as pharmaceutical companies began to
produce more multidose vials to cut costs. Without the preservative, a multidose
vial can become tainted once its seal is broken.
The increase in the use of thimerosal coincided with an increase in the
number of vaccines administered to children. Children today can receive about 36
doses of 11 vaccines by age 5.
And those two trends corresponded with a surge in autism rates throughout the
country, say supporters of the mercury/autism theory. They fear that some
children can't flush all the mercury from their systems, so it builds up and
triggers autism, a neurological disorder that affects communication and
socialization.
Many doctors and scientists say such fears are unwarranted. But if the theory
is so full of holes, the supporters ask, why did the government direct vaccine
manufacturers in 1999 to remove thimerosal and other mercury from common
childhood vaccinations, including hepatitis?
They say the CDC encouragement means children might again be given vaccines
containing mercury. Flu shots have not traditionally been childhood vaccines, so
many multidose vials still contain thimerosal. It is unclear exactly how much of
the flu vaccine supply contains the preservative.
"Promoting flu shots for healthy children concerns me a great deal," said
Miami lawyer Roberto Villasante, co-chairman of the vaccine litigation group for
the Association of Trial Lawyers of America. "I think the big question should
be: Is this vaccine absolutely necessary?"

Kim Dabney was shocked when she heard the news from the CDC last month.
Her son Drew had suffered from earaches and flulike symptoms. They weren't
serious, but they were enough for her pediatrician to recommend that Drew
receive a flu vaccination last year. He was 15 months old.
"After that shot, that was the end of Drew as we knew him," Dabney said.
Drew stopped making eye contact, stopped having fun, stopped making sense.
He had had some trouble after a round of shots administered a few months
earlier, Dabney said, but the flu shot "put him over the edge."
Drew's pediatrician, like some other doctors, had never heard of thimerosal
or theories about a link between vaccinations and autism, Dabney said.
But when Dabney researched Drew's vaccination record, she found it loaded
with shots containing mercury.
The Dabneys, who moved from Miami to Charlotte, N.C., last year, have spent
close to $50,000 on therapy and other treatments for Drew, who is showing marked
improvement.
"No one wants the flu, but no one wants mercury poisoning either," she said.
"Now that these links are showing up, I cannot believe they aren't screaming to
get this stuff off the shelves."
Most members of the medical community think such a move is unnecessary. They
note that many children with risk factors such as cystic fibrosis have received
flu shots for years. If there were a link, many more of those children would
have autism, they say.
Some children don't show signs of autism until they are a few years old. The
vaccinations don't cause it, the doctors argue, they just happen to be given
around the same time.

Barbara Fisher is co-founder and president of the National Vaccine
Information Center, a nonprofit group that advocates reforming the mass
vaccination system. She encourages parents of children in the 6- to 23-month age
group to arm themselves with as much information as possible before they decide
whether to vaccinate their children against the flu.
Even if science never finds a definite link between thimerosal and autism,
it's worth considering, Fisher said.
She recommends that parents who want their children vaccinated against the
flu read the manufacturer's insert that comes with the vaccine to determine
whether it contains thimerosal or any other mercury.
"Parents should not rely solely on their doctors, who don't always have all
the information themselves," she said. "Whatever decision is made, it should be
made from a position of knowledge, not a position of ignorance."
