U.S. kindergarten vaccination rates hit record low

U.S. kindergarten vaccination rates have reached a historic low for the 2025-2026 school year, according to data from the Centers for Disease Control and Prevention (CDC). Vaccination coverage declined for every vaccine tracked by the agency, including measles, mumps, rubella (MMR), polio, and diphtheria, tetanus, and pertussis (DTaP).

Exemptions from vaccine requirements rose to 4.2 percent, up from 3.6 percent the previous year, affecting approximately 155,000 children. Most of these are nonmedical exemptions. This decline occurs alongside a significant measles outbreak, with the U.S. reporting the highest number of measles cases in 35 years.

Medical experts, including representatives from the American Academy of Pediatrics, attribute the decline to confusion within vaccination recommendation systems. The shift follows changes in federal health leadership and policy directions under Health and Human Services Secretary Robert F. Kennedy Jr. and President Donald Trump, including efforts to revise childhood vaccination guidance and spacing out vaccine doses.
