The fraction of kids exempted from vaccine requirements rose to 4.2%, up from 3.6% the previous year, affecting an estimated 155,000 children nationally during the 2025-2026 school year. Exemptions increased in 41 states and the District of Columbia, with most being for nonmedical reasons.
The CDC reported that 92.4% of kindergartners received their required measles-mumps-rubella (MMR) shots, down slightly from the previous year. Before the COVID-19 pandemic, vaccination rates were at 95%, the level considered sufficient to prevent outbreaks. Rates also fell for polio, diphtheria-tetanus-pertussis (DTaP), and chickenpox vaccines.
Experts point to turmoil caused by federal health officials as a primary reason for the decline. U.S. Health Secretary Robert F. Kennedy Jr., a noted vaccine skeptic, has been instrumental in revising childhood vaccination guidance. President Trump recently signed an executive order recommending fewer vaccinations and splitting the MMR vaccine into three separate shots, despite medical organizations dismissing these recommendations as unscientific.
The decline in vaccination rates coincides with the U.S.'s worst measles outbreak since 1991. Over a quarter of a million kindergartners are now susceptible to measles, according to Dr. James Campbell of the American Academy of Pediatrics. The CDC data also shows significant variations in exemption rates across states, with Idaho reporting 17.5% exemptions and Connecticut less than 0.5%. California has maintained high vaccination rates due to strict school entry requirements.
The CDC's data release this year was notably subdued compared to previous years, with only a three-sentence statement encouraging parents to discuss vaccination options with their doctors. Public health officials continue to emphasize the importance of vaccinations in preventing outbreaks and protecting community health.
