Thimerosal-Mercury

Toxic mercury exposure has a wide range of adverse health effects. Currently in the United States there is a public health effort to reduce human exposure to mercury from all sources.

As part of this effort, in July 1999, the U.S. Public Health Service (US PHS) and the American Academy of Pediatrics (AAP) issued a joint statement formally requesting that manufacturers eliminate or reduce the amount of thimerosal (a mercury-containing compound) in vaccines.

While there is no evidence that any child has been harmed by the mercury content of a vaccine, some parents and health care providers still have questions: What is thimerosal? Why is it in some vaccines? Does it present a risk to children? Is it still in the vaccines that children receive? They should be reassured by the report of the Institute of Medicine's Vaccine Safety Committee, however.
