Chicago Department of Public Health Weekly Media Brief, 03202025

The Chicago Department of Public Health (CDPH) is responding to a significant increase in measles cases nationwide, reporting 301 cases and two fatalities in 2025. This alarming trend has prompted CDPH to encourage all residents to verify their measles vaccination status, particularly the measles, mumps, and rubella (MMR) vaccine, which is crucial for long-term protection. While Chicago and Illinois remain free of measles cases this year, the highly contagious nature of the disease means that unvaccinated individuals are at great risk. The MMR vaccine is proven to be safe and effective, and its administration is vital to prevent outbreaks. To assist residents, the Illinois Department of Public Health provides access to immunization records via the Vax Verify portal.

Additionally, the CDPH is offering MMR vaccinations to all individuals regardless of their insurance status, ensuring that everyone has the opportunity to be protected. This proactive approach not only safeguards individual health but also contributes to community immunity. With the ongoing threat of measles, the CDPH's guidance is a crucial resource for public health.
