Oklahoma Kindergarten Exemptions More Than Doubled in Three School Years
Oklahoma’s public school kindergarten vaccination exemption rate climbed from 3.3% in the 2021-22 school year to 7.6% last school year, according to an Oklahoma Department of Health survey. Private school kindergarteners saw an even steeper jump, from 7% to 12.4% over the same period. The overwhelming majority of exemptions filed were for non-medical reasons.
Oklahoma state law allows parents to exempt their children from required vaccinations on grounds of medical necessity, religious belief, or personal belief. The personal belief category carries no evidentiary requirement, making it the easiest path to opt out.
12.4% of private school kindergarteners in Oklahoma received vaccination exemptions last school year, up from 7% in 2021-22.
That rate matters because measles, the most contagious vaccine-preventable disease, requires roughly 95% of a population to be vaccinated to stop an outbreak. Oklahoma County kindergarteners hit only 87% last school year. Tulsa County’s overall childhood vaccination rate is declining.
Low Vaccination Rates Contributed to a Measles Outbreak Last Year
Oklahoma recorded a spike in measles cases last year, during a broader national outbreak. Health officials said most cases involved unvaccinated individuals.
“Being in a school environment puts both the children themselves and their classmates at risk of transmitting infections that could be totally prevented.”
Dr. Steven Crawford, chair, Oklahoma Alliance for Healthy Families, July 2026
Crawford said Oklahoma’s vaccination rates have declined for years, but the steepest drop followed the COVID-19 pandemic, which amplified public skepticism about vaccine safety and efficacy.
Free Vaccines Reach 6,850 Kids Annually But Can’t Overcome Exemption Trends
The Blue Cross Blue Shield Oklahoma Caring Foundation operates several mobile vaccine vans across the state. Last year, those vans reached 6,850 children across 760 stops, providing free immunizations to kids who are uninsured or enrolled in Medicaid.
The program helps address access barriers, but healthcare providers say access is not the primary obstacle. Parents who file personal or religious belief exemptions are choosing not to vaccinate, not failing to find a provider. Oklahoma school enrollment opens next month, meaning unvaccinated children will return to classrooms in August 2026.
What You Can Do Now
-
Contact the Oklahoma State Department of Health at (405) 271-5600 and ask what policy changes the agency is considering to tighten personal belief exemption requirements before the August 2026 school year begins. Ask specifically whether the state plans to require annual renewal or counseling for non-medical exemptions, as several states have adopted.
-
Call your Oklahoma state legislators through the Oklahoma Legislature’s directory at oklegislature.gov and urge them to require education or physician sign-off before granting personal belief exemptions. Tell them Oklahoma’s 7.6% public school exemption rate puts the state below measles herd immunity thresholds.
-
If your child needs vaccinations, contact the Oklahoma Caring Foundation at okcaring.org to find a free mobile vaccine van stop near you before school enrollment deadlines.
-
Share the OSDH exemption data with your local school board. School boards can adopt stricter local notification policies for parents and require exemption paperwork to be resubmitted annually. Find your board at sde.ok.gov.
