NEW YORK |
(Reuters Health) – A new government study adds to the evidence that thimerosal, a mercury-based preservative until recently found in many vaccines, does not increase children’s risk of autism.
It shows kids who had been exposed as babies to high levels of the preservative — through vaccines they received or their mothers received while pregnant — were no more likely to develop autism, including two distinct subtypes of the condition.
“This study should reassure parents about following the recommended immunization schedule,” said Dr. Frank Destefano, director of the Immunization Safety Office at the Centers for Disease Control and Prevention (CDC) in Atlanta, and the study’s senior author.
