Many Studies Have Found Thimerosal In Vaccines To Be Safe

January 12, 2010

Thimerosal is a very effective preservative that has been used since the 1930s to prevent contamination in a number of products including some multi-dose vials of vaccines.

Data from 19 studies show no convincing evidence of harm caused by the low doses of thimerosal in vaccines, except for minor local injection site reactions like redness and swelling at the injection site.
