Chicago Department of Public Health Advises All Chicagoans to Ensure They Are Protected Against Measles as Cases Rise Across the United States

The Chicago Department of Public Health (CDPH) has emphasized the importance of measles vaccinations as cases escalate across the United States, with 301 cases reported and two deaths documented by March 14, 2025. While Chicago has not seen any measles cases this year, a significant outbreak in early 2024 prompted the city to adopt rapid response measures, including mass vaccinations and thorough contact tracing. The CDPH urges residents to verify their immunization status and ensure they are current with the measles, mumps, and rubella (MMR) vaccine, which is crucial for community protection. Vaccination efforts have been intensified in collaboration with local schools, aiming to elevate MMR coverage among children. CDPH provides no-cost vaccinations for eligible children, while those with private insurance or Medicaid are advised to check with local providers.

The CDC reports that two doses of the MMR vaccine are 97% effective against measles, underscoring the necessity of vaccinations, particularly for those planning to travel. As measles cases circulate, residents are strongly encouraged to protect themselves and their families by securing vaccinations before any travel. Ensuring widespread vaccination is essential to preventing outbreaks and safeguarding public health in Chicago.
