Concern has been expressed over the possibility that the mercury-containing compound thimerosal in vaccines may cause autism. It is reasonable to ask whether thimerosal in childhood vaccine increases risk of chronic childhood neurologic disability and specifically of autism. Most of the information we have about mercury toxicity is related to exposure to methyl rather than ethyl mercury.Bernard et al offered an hypothesis that autism is an expression of mercury toxicity resulting from thimerosal in vaccines. This review will examine these issues and others to ask whether, according to evidence now available, thimerosal is a probable cause of autism.
