Illinois health officials have issued new recommendations for residents to receive vaccinations for influenza, COVID-19, and RSV. This guidance follows a difficult 2025-2026 respiratory virus season that saw significant child mortality rates linked to the flu.
Why it matters
Widespread vaccination helps prevent hospitalizations, emergency room visits, and severe long-term complications like Long COVID. By staying up to date, residents protect both their households and vulnerable members of the local Illinois community.
Official reports indicate 85 percent of children who died from influenza in 2025-2026 were unvaccinated, while prior 2024-2025 data shows vaccines prevented 180,000 hospitalizations and 12,000 deaths. Additionally, the MMR vaccine maintains a 97 percent effectiveness rate against measles after two doses.
The players

Cook County Department of Public Health

The details
Vaccines for influenza, COVID-19, and RSV are currently available at pharmacies across the Chicago area to curb anticipated infection levels. Health officials also highlighted that 23 measles cases were confirmed in Illinois throughout 2026, prompting new efforts to encourage MMR vaccination.
Timeline
Vaccines prevented 180,000 hospitalizations during the 2024-2025 season.
Children's flu hospitalizations hit a near-record high in 2025-2026.
Illinois confirmed 23 measles cases during 2026.
Cook County suburban vaccination clinics begin on October 5, 2026.
The Big Picture
The current state guidance aligns with the long-term national protocols established by the Advisory Committee on Immunization Practices (ACIP) influenza vaccination schedule.
Residents can access immediate protection by scheduling their vaccinations at local retail pharmacies or upcoming community clinics. These measures are designed to reduce the risk of severe illness and prevent the need for emergency medical intervention throughout the season.
The takeaway
Prioritizing vaccinations serves as a primary defense against seasonal outbreaks that historically overwhelm healthcare systems. Residents should consult with their healthcare providers to ensure their immunization records are current for both seasonal viruses and measles.
What happens next
The Cook County Department of Public Health will host a series of suburban vaccination clinics starting October 5, 2026.
