Robert F. Kennedy Jr. falsely claims measles vaccine protection 'wanes very quickly'

Summary
Robert Kennedy Jr.'s false claims about the measles vaccine are endangering public health. He asserts the vaccine isn't safety tested and its protection wanes quickly, directly contradicting scientific evidence. The MMR vaccine is rigorously tested and provides long-lasting protection, with two doses being approximately 97% effective. Kennedy Jr.'s misinformation undermines public trust, increases the risk of measles outbreaks, and strains healthcare systems. His anti-vaccine activism, through groups like Children's Health Defense, exacerbates the problem. Countering misinformation requires healthcare provider communication, public health campaigns, social media accountability, and fact-checking initiatives to prioritize science and protect public health.
