IOM Report Immunization Safety: Vaccines & Autism

This eighth and final report of the Immunization Safety Review Committee examines the hypothesis that vaccines, specifically the measles-mumps-rubella (MMR) vaccine and thimerosal-containing vaccines, are causally associated with autism. The committee reviewed the extant published and unpublished epidemiological studies regarding causality and studies of potential biologic mechanisms by which these immunizations might cause autism. Immunization Safety Review: Vaccines and Autism (2004) finds that the body of epidemiological evidence favors rejection of a causal relationship between thimerosal-containing vaccines and autism.
