Lyn Redwood is an American nurse practitioner and vaccine safety advocate who became one of the most recognized figures in the anti-vaccine movement. She is best known as President Emerita of Children’s Health Defense (CHD), the organization founded by Robert F. Kennedy Jr. With over 25 years of clinical experience in pediatrics and family medicine, Lyn moved into advocacy after her son’s autism diagnosis, which she linked to mercury in vaccines.
Over the years, she co-authored papers, testified before Congress, served on federal committees, and appeared in national media. In 2025, she made headlines again when she joined the CDC’s Immunization Safety Office under RFK Jr.’s leadership at HHS, a move that sparked major controversy because of her history of promoting debunked claims about thimerosal and autism.

She also helped launch the National Autism Association in 2003, serving as Director Emerita.
She testified before Congress in 2000 and 2004 about mercury in vaccines and went on to serve as a public member of the NIH Interagency Autism Coordinating Committee (2007–2014). She was also involved in the Department of Defense Autism Research Program.

Controversies
Lyn Redwood has been at the center of vaccine debates for over two decades. Her claims linking thimerosal to autism have been rejected by mainstream science and public health agencies. Despite thimerosal being removed from most vaccines since 1999, she has continued to argue that it causes neurological harm.
Her appointment to the CDC in 2025 under RFK Jr. drew bipartisan criticism. Senator Patty Murray and other lawmakers called the move “deeply disturbing,” warning that it could undermine vaccine confidence. At an ACIP meeting in June 2025, she presented on thimerosal but was later forced to correct errors after citing a nonexistent study, fueling criticism from scientists.
While her supporters view her as a determined advocate for families affected by autism, critics accuse her of spreading misinformation that risks public health.
