Kennedy appoints anti-vaccine advocate Lyn Redwood to HHS role

In early 2024, Robert F. Kennedy Jr., serving as the Secretary of the Department of Health and Human Services (HHS) in the United States, appointed Lyn Redwood, a longstanding ally and anti-vaccine advocate, to an unspecified position within the department. Redwood has been a vocal critic of vaccines, particularly in relation to thimerosal, a preservative that contains ethyl mercury. Her belief that thimerosal contributes to autism aligns with Kennedy's controversial views on vaccine safety. This appointment raised alarm among public health experts who fear it may lead to detrimental changes in vaccine communication and public health policy. The recent move came in the wake of Kennedy dismissing all members of the Advisory Committee on Immunization Practices (ACIP) and replacing them with individuals who share his anti-vaccine stance. This committee, crucial for shaping vaccine recommendations in the U.S., was previously composed of respected experts in immunization. Kennedy's actions were part of a broader strategy to promote his views against established scientific conclusions. He seems intent on undermining decades of research that has found no causal link between vaccines and autism, including thimerosal's safety. Redwood is notably scheduled to present at a meeting of ACIP, where she intends to utilize a report on thimerosal that has come under fire for containing misleading information. Scientific figures, including Robert F. Berman, have identified discrepancies in the evidence Redwood has planned to present, specifically the questionable citation of studies that do not exist. Despite past claims from the CDC that thimerosal poses no substantial risk, Redwood's beliefs stubbornly persist, reflecting a significant divide between mainstream science and the anti-vaccine rhetoric championed by Kennedy and Redwood. Experts have expressed profound concern regarding Redwood’s potential influence on federal vaccine policy. Critics argue that her presence in HHS could foment public distrust toward vaccination, potentially leading to increased vaccine hesitancy. Such scenarios could undermine decades of public health progress, particularly in reducing vaccine-preventable diseases. As vaccination rates drop, the resulting health consequences could lead to more outbreaks, hospitalizations, and even deaths among vulnerable populations. This tumultuous climate around vaccine safety and efficacy highlights the urgent need for robust counter-narratives and informed public health messaging.
