Study Finds Vaccine Preservative Is Not Linked to Risks of Autism

By THE ASSOCIATED PRESS

LOS ANGELES (AP) — Autism cases in California continued to climb even after a mercury-based vaccine preservative that some people blame for the neurological disorder was removed from routine childhood shots, a study has found.

Researchers from the State Public Health Department found that the autism rate in children rose continuously in the study period from 1995 to 2007. The preservative, thimerosal, has not been used in childhood vaccines since 2001, except for some flu shots.

Doctors said that the latest study added to the evidence against a link between thimerosal exposure and the risk of autism and that it should reassure parents that vaccinations do not cause autism. If there was a risk, the doctors said, autism rates should have dropped from 2004 to 2007.

Dr. Geschwind, a neurologist at the Geffen School of Medicine at the University of California, Los Angeles, said the focus should be on exploring possible causes of autism, including genetic links.

“Something else must be at play,†said Dr. Geschwind, who had no connection with the study. “And we need to know what that is if we’re really serious about preventing autism.â€

The results of the study are in the January issue of The Archives of General Psychiatry. The study did not explore why autism cases increased.

Officials say one in 150 American children have autism, higher than other estimates. Researchers say it is unclear whether the increase stems from changes in classifying autism or whether the increase is actual.
