Vaccine traffic at Kansas City health clinics has fallen as much as 30% compared to a year ago, according to the Kansas City Health Department, even as the United States logs its worst measles year in more than three decades. The drop comes as national vaccine exemption rates climb and a new federal executive order reshapes recommendations for the childhood immunization schedule, leaving parents across the metro with conflicting signals about what shots their kids actually need.
The Centers for Disease Control and Prevention has reported 2,550 measles cases across 47 jurisdictions during 2026, part of what the Lawrence Journal-World describes as the nation's largest measles outbreak in decades. The country confirmed 2,289 measles cases in 2025 alone, with 48 outbreaks recorded that year and another 38 new outbreaks reported so far in 2026, according to the same report. Southwest Kansas experienced its own measles outbreak in 2025, a reminder that the disease has not stayed confined to distant headlines.
Locally, the numbers paint an uneven picture of protection. The Johnson County Department of Health and Environment reported vaccination demand declined 20%, while Wyandotte County kindergartners received required vaccinations at just 72% during the 2024-25 school year, far short of the 95% vaccination rate public health experts say is needed for measles herd immunity. The Wyandotte County Public Health Department separately reported in July that only 83% of local kindergartners completed their recommended measles series before starting school, trailing both the state and national benchmarks. According to the Wyandotte County Public Health Department, multiple locations offered walk-in vaccination clinics for 7th- and 11th-grade students only during the 2024-2025 school year, with no appointment needed.
Exemptions Climb Across the Metro
Exemptions Climb Across the Metro Missouri kindergartners received religious exemptions from vaccines at a rate of 6% during the 2025-26 school year, while Kansas kindergartners received religious exemptions at 3.3% during 2024-25. One Kansas City-area ZIP code, 64155, registered a kindergarten vaccination rate of 84%, and its religious exemption rate doubled from 7% to 14%. Missouri's kindergarten MMR vaccination rate was about 90% in 2024-25.
Kansas has seen its own steady slide. Kansas kindergartners received religious exemptions at a rate of 3.3% during 2024-25, with 22 Kansas counties recording overall kindergarten vaccination rates below 75%, according to the Medical Society of Sedgwick County. Vaccination rates have declined steadily since 2020, a trend that predates the current federal policy fight but has accelerated alongside it. According to the Kansas Department of Health and Environment, MMR immunization coverage among Kansas kindergarten students during the 2023-2024 academic year was estimated at roughly 93%, below the herd immunity threshold. According to the Kansas Department of Health and Environment, an outbreak in Johnson and Sedgwick Counties in June–July 2014 involved 14 confirmed measles cases.
Federal Order Adds to the Confusion
President Donald Trump, who returned to office in 2025 and appointed Robert F. Kennedy Jr. as health secretary, issued an executive order on August 11, 2026, calling for changes to the childhood vaccine schedule. The Trump administration proposed splitting the combined MMR vaccine into individual shots and spreading childhood vaccines over a longer period, with sources describing reductions in the number of diseases or vaccines covered from 13 to 7, 18 to 11, or 17 to 11. Individual measles, mumps and rubella shots are currently unavailable in the United States, and the MMR vaccine has been used for five decades.
Health officials have warned that extending the vaccine schedule could cause children to miss vaccine protection during the gap. Medical organizations have rejected the proposed changes, and the American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Obstetricians and Gynecologists all recommend following the long-standing childhood vaccine schedule instead. More than 210 national medical and public health organizations, including the Infectious Diseases Society of America, released a joint statement opposing the executive order, warning that paring back and spacing out vaccines bypasses scientific review and increases confusion — a concern echoed by Hoodline's earlier reporting on big-city health leaders pushing back nationally.
Existing State Rules Remain Unchanged
Despite the federal shakeup, state and local officials stress that nothing has actually changed for Kansas City-area families yet. The Missouri Department of Health and Senior Services said Missouri vaccination requirements have not changed, and the Kansas Department of Health and Environment said Kansas vaccine requirements will not change either. Jill Bronaugh said Kansas guidance had not changed, and Lauren Grimes said school immunization requirements had not changed.
Existing vaccine schedule shots will remain available and covered by insurance and government programs, officials note. Kansas City Public Schools requires proof of immunization by the first day of school. Under Missouri Revised Statutes Section 167.181, parents can exempt children from mandatory school immunizations by filing a written objection citing religious beliefs, while Missouri regulation 19 CSR 20-28.010 sets immunization requirements. Kansas law requires proof of vaccination.
Health Officials Urge Caution as Cases Climb
Kansas City Health Director Marvia Jones said on August 14 that families should continue following the CDC-recommended vaccination schedule, and she has urged parents to ask questions and consult their children's doctors before skipping vaccinations. Charlie Hunt said people should be worried about declining vaccination rates and the measles resurgence. Officials also warn that parents may choose more exemptions if vaccine rules become more complicated and confusing — a dynamic already visible in Illinois, where Hoodline has reported exemptions nearly doubling from 3.6% to 4.2% amid similar confusion.
The stakes of that hesitancy are steep. Measles causes death in one of every 1,000 infected children, and the virus can cause encephalitis and pneumonia, as well as erase a child's existing immune memory to other diseases. Unvaccinated people exposed to measles may need to miss school or work during quarantine. Scientists have found no link between vaccines and autism, officials note, even as skepticism continues to shape parental decisions. Nationally, a KFF analysis of CDC data found kindergarten vaccine exemption rates rose to a record 4.2% for the 2025-2026 school year, up from 3.6% the year before.
