- The CDC's Advisory Committee on Immunization Practices is reviewing vaccine recommendations, including a discussion on thimerosal.
- Thimerosal, a mercury-containing preservative, has been removed from all childhood vaccines and does not cause neurodevelopmental disorders.
- Ethylmercury in thimerosal is quickly cleared by the body, unlike methylmercury, which bioaccumulates and is more toxic.
- Thimerosal was first added to vaccines in the 1930s to prevent contamination by fungi or bacteria.
- In the late 1990s, thimerosal was removed from childhood vaccines due to theoretical risks, despite no direct evidence of harm.
- Current research confirms thimerosal does not increase neurodevelopmental risks or cause autism.
- Thimerosal remains in some adult vaccines, primarily in multidose flu vials, to prevent contamination.
