A previously unreleased confidential report from the US Centers
for Disease Control reported that an exposure to more than 62.5
micrograms of mercury within the first three months of life more
than doubled a child's risk of developing autism. The US legal
firm Waters & Kraus, who were representing many families in
a class action, indicated that in many of the cases the firm evaluated,
the affected child had received more than 62.5 micrograms of mercury
through paediatric vaccines in the first three months of life.
A public version of the report released at the time suggested
that its findings were inconclusive on the issue of whether the
mercury-based vaccine preservative thimerosal had contributed
to the US's epidemic of regressive autism and other neurological
disorders in small children.

In 2000, Sally Bernard and colleagues (Autism: A unique type
of mercury poisoning) linked the mercury-based preservative thimerosal
(ethyl mercury thiosalicylic acid) not only to autism but to related
syndromes such as attention deficit hyperactivity disorder (ADHD).
Thimerosal is used widely as a preservative in vaccines, antitoxins,
tuberculin tests and desensitisation solutions. It may also be
found in soap-free cleansers, nose, eye, and ear drops, eye ointments,
topical medications, antiseptic sprays, cosmetics (including makeup
removers, eye moisturisers, and mascaras) and cleaning fluids
for contact lenses.
UK regulators have recommended phasing out its use in vaccines.
