This site provides the CDC's position on recent research on autism and Thimerosal: "Some people believe increased exposure to thimerosal ... explains the higher prevalence in recent years. However, evidence from several studies examining trends in vaccine use and changes in autism frequency does not support such an association." From the Centers for Disease Control and Prevention (CDC).
