Robert F. Kennedy Jr.
Anti-Vaccine Empire Builder

Robert F. Kennedy Jr. is an environmental attorney, political figure, and founder of Children's Health Defense, an organization focused on vaccine safety concerns and what it characterizes as unchecked pharmaceutical industry influence. He ran for president in 2024 and subsequently served in a public health advisory capacity. He is also among the individuals identified by the Center for Countering Digital Hate's 2021 "Disinformation Dozen" report as generating a significant share of anti-vaccine social media content, a characterization he has disputed.
Kennedy has argued for decades that evidence linking certain vaccines to adverse health outcomes, including potential links to autism, deserves more rigorous investigation and that regulatory agencies are insufficiently independent from the pharmaceutical industry. Medical and scientific organizations, including the CDC and WHO, maintain that the vaccine-autism link has been thoroughly studied and rejected, and that the original paper suggesting such a link was retracted due to data fabrication. Kennedy contests the framing of his position as misinformation, arguing instead that he is raising legitimate safety questions that are being suppressed.
During the COVID-19 pandemic, Instagram permanently removed Kennedy's account for violations of its vaccine misinformation policies. He had maintained an audience of several million followers there. Members of his own family publicly criticized his anti-vaccine advocacy, describing it as harmful. At a January 2022 rally opposing vaccine mandates, Kennedy compared public health policies to the Holocaust, drawing condemnation from civil rights organizations and some members of his own family; he subsequently expressed regret for the comparison while maintaining his opposition to the policies themselves.
Children's Health Defense has grown into a substantial organization with annual revenues in the millions of dollars, a legal program that files suits related to vaccine policy, and a content operation that produces health news coverage from an anti-vaccine-mandate perspective. Kennedy's supporters regard his work as necessary advocacy in defense of medical freedom and informed consent. Public health authorities and medical organizations maintain that his campaigns have contributed to vaccine hesitancy with measurable public health consequences.
