As Robert F. Kennedy Jr. reshapes federal vaccine policy under Donald Trump, long-standing protections are being weakened. The CDC’s vaccine schedule has shifted, federal guidance is growing less clear, and anti-vaccine activists are seizing the moment. In Florida and other states, lawmakers are already moving to roll back school and childcare vaccination requirements. If this spreads, outbreaks of measles, whooping cough, and other preventable diseases will follow. Tell state leaders: “Don’t roll back vaccination requirements. Protect kids, follow evidence, and keep communities safe.” School vaccine requirements are one of the greatest public health successes in American history. They are why deadly childhood diseases stopped ripping through classrooms and why millions of children grew up healthy. These protections safeguard newborns too young to be vaccinated, children with compromised immune systems, and entire communities that rely on high vaccination rates to stay safe. Public health experts are clear: when vaccination rates fall, outbreaks rise. Lives are put at risk, and rebuilding trust can take years. We can’t allow ideology to override science and the safety of our children. Governors and state legislators control school entry rules and public health codes, which means states are now the firewall. They must choose science over politics. Add your name to demand state leaders everywhere protect vaccine requirements to keep our families safe and healthy. The petition to state leaders reads: “Don’t roll back vaccination requirements. Protect kids, follow evidence, and keep communities safe.”
