Illinois continues to maintain high childhood vaccination rates despite national debates and uncertainty surrounding immunizations, according to data released Monday by the Illinois Department of Public Health. As of October, over 95% of children statewide had received the 10 vaccines required for school entry, including protections against chickenpox, whooping cough, hepatitis B, measles, and polio. The only exception was the meningococcal vaccine, which reached 94.4% coverage.

Though the overall vaccination rates improved slightly compared to the previous school year, certain areas within the state, including parts of Chicago and counties in the northwest and far southern regions, showed pockets of lower uptake for multiple vaccines. In Chicago, for example, vaccination rates dipped below 95% for several key immunizations: 92.7% for the diphtheria, tetanus, and whooping cough vaccine, 88.8% for meningococcal vaccine, 93.6% for polio, and 92.6% for an older child vaccine also protecting against diphtheria, tetanus, and whooping cough. The new data indicate that more than 200 Chicago Public Schools have vaccination rates below 90% for some vaccines.

Chicago Public Schools acknowledged the challenges but reported progress. The district highlighted ongoing efforts to increase immunization rates through frequent communication with families and school administration, regular data reviews, and collaboration with local health services. Free vaccines are offered in partnership with the city health department, including through school-based and mobile clinics, as well as local hospitals and providers.

“These numbers validate our efforts to make vaccines more accessible,” Governor JB Pritzker said in a statement, crediting the Illinois Department of Public Health, the State Board of Education, healthcare workers, and families for contributing to the high rates. Dr. Jennifer Seo, pediatric medical adviser at the state health department, noted Illinois remains well protected overall but acknowledged the need for targeted interventions in specific schools or areas to raise coverage further. She attributed the state's success to coordinated efforts among state agencies, local health departments, providers, schools, and community organizations, as well as the rollout last year of mobile vaccination programs designed to enhance access.

The recently released figures come amid a wave of national vaccine skepticism and policy shifts. Last year, the United States recorded over 2,200 measles cases—the highest tally in more than three decades—driving renewed focus on immunization. Meanwhile, U.S. Health Secretary Robert F. Kennedy Jr., known for his skeptical stance on vaccines, replaced members of a federal vaccine advisory committee and supported reducing recommended vaccines for children. These federal changes, which included scaling back recommendations for flu, rotavirus, hepatitis, meningitis, and respiratory syncytial virus (RSV) vaccines, were temporarily blocked by a federal judge following a lawsuit initiated by the American Academy of Pediatrics and other medical groups.

In contrast to federal shifts, Illinois has established its own vaccine guidelines, adopting a schedule developed by the American Academy of Pediatrics in February. This follows legislation signed by Pritzker last year that formalized the state’s ability to issue independent vaccine recommendations amid concerns over federal changes.

Healthcare providers in Illinois report increased dialogue with parents stemming from the vaccine debate. Dr. Jasmine Saavedra of Esperanza Health Centers said many parents raise questions but are generally convinced by informed discussions. “I think it just speaks volumes to the trust our patients have in their providers and the healthcare system,” she said.

At the Brighton Park North clinic on Monday, 12-month-old Naomi Carrera received vaccines protecting against pneumococcal disease, mumps, rubella, hepatitis A, and chickenpox, despite her distress. Her mother, Maria Carrera of Ashburn, said her older children were fully vaccinated and intends to continue the practice to ensure her youngest remains healthy.
