Thimerosal

Thimerosal

Thimerosal (ethyl mercury) is a widely used preservative in biologic and medical products. Since 2001, all vaccines routinely recommended for children 6 years of age and younger are thimerosal-free, with the exception of some formulations of inactivated influenza vaccine. Numerous studies have since shown that there is no relationship between vaccines, either with or without thimerosal, and the development of autism or other neurologic problems in children.

The Institute of Medicine is an impartial group of the world’s leading experts that advises Congress on science issues. After reviewing more than 200 studies in 2004 and more than 1,000 studies in 2011, the consensus report strongly stated that the evidence did not show a link between vaccines and autism.
