U.S. kindergarten vaccine exemptions climbed to a new record while coverage slipped again, widening the risk window for school outbreaks.
Story Snapshot
- Exemptions rose to 3.6% in 2024–2025, up from 3.3% the year before.
- Thirty-six states and Washington, D.C., saw increases in exemptions; 17 topped 5%.
- Most exemptions are nonmedical, not doctor-ordered health exceptions.
- Lower coverage and higher exemptions increase the risk of outbreaks in schools.
Record exemptions and a steady slide in school immunity
Federal data show a clear trend. Exemptions among kindergarteners rose for another year, hitting 3.6% nationally in 2024–2025, up from 3.3% a year earlier. State maps tell the same story, with exemptions increasing in 36 states and Washington, D.C., and passing 5% in 17 states.
Reporters and health briefings flagged the pattern as part of a multi-year slide that began after the pandemic, with coverage falling and exemptions setting new highs each year.
Coverage is drifting down, but exemptions drive the headline risk. The Centers for Disease Control and Prevention tracks exemptions by type. Medical exemptions remain rare.
Nonmedical exemptions, including religious and personal belief categories permitted under state law, account for more than nine out of ten exemptions in recent years. That mix matters because it reflects policy choices, paperwork paths, and how easy it is to opt out, not a surge in clinical contraindications.
Why state rules shape the map
States set school vaccination requirements and define exemption options. Almost every state requires four core shots for kindergarten entry: measles, mumps, and rubella; diphtheria, tetanus, and pertussis; polio; and varicella. All states allow medical exemptions.
Many also allow religious or personal belief exemptions. Where the process is looser, exemption rates are higher, and clusters can form that fuel outbreaks in a single county or district.

School procedures matter as much as statutes. Research has shown that simple steps—clear written instructions, firm deadlines, and consistent follow-up—lower exemptions. Lax paperwork and easy opt-out paths raise them.
That is not a theory problem; it is an operations problem. Districts that tighten auditing and require timely documentation see coverage rebound without new laws. Parents still make choices, but schools set the guardrails that protect shared classrooms.
The real-world stakes: measles does not need a majority
Measles finds the gaps. Health officials warn that when coverage dips into the low nineties and exemptions top five percent in pockets, measles can spread in a school before anyone notices the first rash. One child with measles can infect many others in a day.
That is why officials watch kindergarten coverage so closely. The first year of school mixes new peers, busy parents, and many classrooms. Small declines can flip a district from safe to shaky fast.
Americans line up with practical prevention and local control. Parents deserve straight facts, not scare tactics. Schools owe families clear rules that are simple, fair, and enforced. Lawmakers set the lanes. Medical exemptions should stay for children who need them.
Nonmedical exemptions should be deliberate, not casual. If a state keeps them, a signed annual form and a short counseling video are reasonable guardrails that protect both liberty and public order.
What works without drama
Three steps help restore balance. First, clean the roster. Districts should chase missing records early and often; many “exemptions” are really paperwork gaps. Second, make the path consistent. One statewide form, one renewal date, and one set of instructions cut confusion and gaming. Third, focus on hotspots.
County health teams can support schools where exemption rates exceed 5%, with on-site clinics and direct outreach that bring families current before the bell rings.
