U.S. Health Secretary Robert F. Kennedy Jr. will give a keynote speech at an upcoming anti-vaccine conference in Washington, D.C. The event is being hosted by Children's Health Defense (CHD), an organization that has long opposed widespread vaccination. CHD announced on Monday that Kennedy has agreed to participate in the conference. Kennedy will join other prominent figures in the anti-vaccine movement, including Andrew Wakefield, a former doctor who is now a central figure in the anti-vaccine community. Wakefield was stripped of his medical license in 2010 after a medical board found that he conducted unethical research on children and falsely claimed a link between the measles, mumps, and rubella (MMR) vaccine and autism. His research was later retracted due to serious flaws and fraud. Wakefield's claims, though discredited by the scientific community, have had a lasting impact on public perception of vaccines. Despite being excluded from mainstream medicine, he continues to influence the anti-vaccine movement, which has grown in visibility over the years. His theories have been amplified by groups like CHD, which has worked to promote the idea that vaccines are harmful. Kennedy's involvement in the conference has drawn attention, as he now holds a high-profile government position. His presence at the event has raised questions about how his current role aligns with the views he has previously expressed. The conference is expected to focus on topics related to vaccine safety and alternative health practices, though it has faced criticism for promoting misinformation about immunizations.
