Does the MMR vaccine contain thimerosal?

No MMR vaccine has ever contained thimerosal. Today, with the exception of some flu vaccines, none of the vaccines used in the U.S. to protect preschool children against infectious diseases contain thimerosal as a preservative. The minute amounts of thimerosal found in a few of the recommended childhood vaccines are an unavoidable by product of the production process and no harmful effects have ever been reported or found with these doses of thimerosal in vaccine. Top • Can vaccines that contain thimerosal cause autism? Although the evidence is strong that the MMR vaccine does not cause autism, new concerns have developed about possible neurodevelopmental effects, including autism, from exposure to the mercury-containing preservative, thimerosal. Thimerosal was used in certain vaccines given to infants prior to 1999. No association has been verified between any serious health outcomes and the use of thimerosal as a preservative in vaccines.
