Abstract

Understanding Thimerosal, Mercury, and Vaccine Safety Understanding Thimerosal, Mercury, and Vaccine Safety ➤For more information on vaccines, vaccine-preventable diseases, and vaccine safety: http://www.cdc.gov/vaccines/conversations Last reviewed Februar y 2013 • Thimerosal is a mercur y-containing compound that prevents the growth of dangerous bacteria and fungus. It is used as a preservative for flu vaccines in multi-dose vials, to keep the vaccine free from contamination. Thimerosal is also used during the manufacturing process for some vaccines to prevent the growth of microbes. • In 1999, as a precautionar y measure, the U.S. Public Health Ser vice recommended removing thimerosal as a preservative from vaccines to reduce mercury exposure among infants as much as possible. • Today, except for some flu vaccines in multi-dose vials, no recommended childhood vaccines contain thimerosal as a preservative. • In all other recommended childhood vaccines, no thimerosal is present, or the amount of thimerosal is close to zero. • No reputable scientific studies have found an association between thimerosal in vaccines and autism. • There are two different compounds that contain mercury: ethylmercur y and methylmercury. The low levels of ethylmercury in vaccines are broken down by the body differently and clear out of the blood more quickly than methylmercury. | questions and answers | What is thimerosal?
