Summary
More measles cases had been reported to the CDC by July 23 than in any full year since 1991, pushing the U.S. past last year’s three-decade high in less than seven months.
At least 4,850 infections and three deaths have been recorded since the start of 2025, including two unvaccinated girls in West Texas, even though MMR shots are widely available and often free.
Robert F. Kennedy Jr. and President Donald Trump are described as recasting federal vaccine policy, with a new Trump executive order and earlier CDC decisions seen as reinforcing doubts about vaccine safety.
Health officials and former CDC immunization leaders warn measles is the first sign of wider breakdowns in vaccine protection, raising fears that other preventable diseases could return and that vaccine access itself could be disrupted.

U.S. Measles Cases Surge Past 2,500 in 2026: How Falling Vaccination Rates Threaten Elimination Status and Public Health
Overview
A historic rise in vaccine hesitancy and nonmedical exemptions has driven the US kindergarten MMR vaccination rate down to 92.4%, leaving about 280,000 children unprotected and creating vulnerable pockets across the country. As a result, the US has faced massive measles outbreaks since 2025, with cases surpassing 2,500 by mid-2026 and the virus spreading continuously for over a year. This ongoing transmission puts the nation on the verge of losing its measles elimination status. The crisis is worsened by federal policy changes, declining public trust, and weakened local health responses, leading to severe health, economic, and societal consequences.
