A former anti-vaccine group leader, Lyn Redwood, will present on thimerosal in flu vaccines at a CDC meeting. Thimerosal, a vaccine preservative, was largely removed decades ago due to mercury concerns, despite studies showing no link to neurodevelopmental issues. Redwood's presentation has raised concerns within the public health community, given her history with anti-vaccine groups and debunked claims linking vaccines to autism. While most children's flu vaccines are thimerosal-free, some multidose vials still contain it, prompting this unusual discussion and vote by the newly appointed CDC advisory committee.
