Just a few months after the nation's top medical adviser rejected a link
between vaccines and autism, a mouse study has reignited the debate and
raised new fears among parents considering vaccinations and flu shots for
their kids.

For years, a cadre of parents and physicians have contended that thimerosal,
an ethyl-mercury compound that has been one of the most widely used vaccine
preservatives, is partly responsible for an apparent rise in autism in
recent decades. But broad population studies haven't supported the claim. In
May, a major report from the Institute of Medicine's Immunization Safety
Review Committee rejected a link between autism and vaccines.

But today, a congressional committee will review a June study from Columbia
University, which found that a preservative used in vaccines can cause
autism-like symptoms in a specific strain of mice. The research raises
questions about whether some people might be genetically vulnerable to the
effects of thimerosal.

The study also raises questions about a new push by the Centers for Disease
Control and Prevention to add flu shots to the immunization schedule for
school-age kids. The vast majority of flu shots given still contain the
preservative.

In the study, researchers administered thimerosal to four strains of young
mice. Three of the mice strains were unaffected by thimerosal, but the
fourth developed problems consistent with autism such as delayed growth,
social withdrawal and brain abnormalities. The mice were known to have a
genetic susceptibility to mercury.

Thimerosal, found in childhood vaccines, can increase the risk of
autism-like damage in mice

A new study indicates that postnatal exposure to thimerosal, a mercury
preservative commonly used in a number of childhood vaccines, can lead to
the development of autism-like damage in autoimmune disease susceptible
mice. This animal model, the first to show that the administration of
low-dose ethylmercury can lead to behavioral and neurological changes in the
developing brain, reinforces previous studies showing that a genetic
predisposition affects risk in combination with certain environmental
triggers. The study was conducted by researchers at the Jerome L. and Dawn
Greene

Infectious Disease Laboratory at the Mailman School of Public Health,
Columbia University. Over the past 20 years, there has been a striking
increase--at least ten-fold since 1985--in the number of children diagnosed
with autism spectrum disorders. Genetic factors alone cannot account for
this rise in prevalence. Researchers at the Mailman School, led by Dr. Mady
Hornig, created an animal model to explore the relationship between
thimerosal (ethylmercury) and autism, hypothesizing that the combination of
genetic susceptibility and environmental exposure to mercury in childhood
vaccines may cause neurotoxicity.

Cumulative mercury burden through other sources, including in utero
exposures to mercury in fish or vaccines, may also lead to damage in
susceptible hosts. Timing and quantity of thimerosal dosing for the mouse
model were developed using the U.S. immunization schedule for children, with
doses calculated for mice based on 10th percentile weight of U.S. boys at
age two, four, six, and twelve months.

The researchers found the subset of autoimmune disease susceptible mice with
thimerosal exposure to express many important aspects of the behavioral and
neuropathologic features of autism spectrum disorders, including:

Abnormal response to novel environments;

Behavioral impoverishment (limited range of behaviors and decreased
exploration of environment); Significant abnormalities in brain
architecture, affecting areas subserving emotion and cognition; Increased
brain size.

These findings have relevance for identification of autism cases relating to
environmental factors; design of treatment strategies; and development of
rational immunization programs. The use of thimerosal in vaccines has been
reduced over the past few years, although it is still present in some
influenza vaccines. Identifying the connection between genetic
susceptibility and an environmental trigger for autism--in this case
thimerosal exposure--is important because it may promote discovery of
effective interventions for and limit exposure in a specific population,
stated the lead author Dr. Mady Hornig. Because the developing brain can be
exposed to toxins that are long gone by the time symptoms appear, clues
gathered in these animal models can then be evaluated through prospective
human birth cohorts--providing a powerful to tool to dissect the interaction
between genes and the environment over time.
