US School Vax Rates Drop, Exemptions Hit Record High Amid Policy Chaos!
Kindergarten vaccination rates in the U.S. plummet, with a record 4.2% of children exempted for nonmedical reasons. Learn how policy changes and confusion are fueling this alarming trend. #VaccineCrisis
U.S. kindergarten vaccination rates have continued their downward trend, with federal data released this Monday showing a significant rise in exemptions to an all-time high. For the 2025-2026 school year, the fraction of children excused from vaccine requirements climbed to 4.2%, a notable increase from 3.6% the previous year. This translates to an estimated 155,000 children nationwide, marking the fourth consecutive year that the national average exemption rate has set a new record. The overwhelming majority of these exemptions are for nonmedical reasons, reflecting a growing sentiment among parents to withhold shots.
This concerning trend isn't happening in a vacuum. Experts point to a period of “chaos and confusion” within federal vaccination recommendation systems. A key factor in this turmoil is the influence of U.S. Health Secretary Robert F. Kennedy Jr., a prominent figure in the antivaccine movement before his appointment. Kennedy Jr. and other federal officials have, over the past 18 months, reportedly attempted to revise and scale back childhood vaccination guidance. Further complicating the landscape, President Donald Trump recently called for revamped childhood vaccination recommendations, promoting his theory that shots should be spaced out across separate medical visits, a notion largely discredited by the medical community.
The impact of these declining rates is visible across various essential vaccines. The CDC reported that only 92.4% of 2025-26 kindergarteners received their required measles-mumps-rubella (MMR) shots, a slight drop from the prior year. This figure is particularly troubling as it falls below the 95% vaccination rate typically considered necessary to establish herd immunity, which prevents a single infection from triggering a wider outbreak. Before the COVID-19 pandemic, the MMR vaccination rate stood at 95%. Similar declines were observed in vaccination rates for polio, the diphtheria, tetanus, and pertussis (DTP) combination shot, and the first dose of the chickenpox vaccine. The rate for hepatitis B, however, remained stable, likely due to its administration shortly after birth.
