Large Pennsylvania Measles Outbreak and Falling Coverage

Pennsylvania's measles outbreak is near or above 1,000 reported cases, with hospitalizations and a death, and continues to affect unvaccinated people and infants disproportionately. Early-dose vaccination may be advised for infants in outbreak areas under current CDC guidance; public messaging should verify current recommendations and emphasize routine vaccination, outbreak-specific advice, and high vaccine effectiveness. A multistate lawsuit over reduced childhood-vaccine recommendations and ACIP changes adds policy uncertainty.
