CDC Reports 2,255 Measles Cases as RFK Jr. Weakens Vaccine Programs

The CDC reported 2,255 confirmed measles cases in the United States by July 7, 2025, the highest count since measles was declared eliminated in 2000. Health Secretary Robert F. Kennedy Jr. had simultaneously weakened federal vaccine promotion programs, removed pro-vaccine messaging from CDC websites, and questioned the MMR vaccine's safety record. Public health officials warned that herd immunity thresholds were eroding in communities targeted by anti-vaccine outreach.
