Do immunizations cause autism?

No. Countless studies, including a study performed by the CDC in 2013, have found immunizations are a safe and effective way to prevent serious disease. The studies show there is NO link between autism and the MMR vaccine, thimerosal or multiple vaccines given at once. The below link to a brochure entitled “Understanding Thimerosal, Mercury, and Vaccine Safety” also includes the references to several studies on this topic for more information. The most common side effect of vaccines is soreness at the spot where the shot was given and low-grade fevers that are not harmful.
