Chicago Students Reach Key Measles Immunity Rate
5 Dec
Summary
- Measles vaccination rates in Chicago Public Schools have increased.
- CPS students have now reached the 95% vaccination target for herd immunity.
- Health officials emphasize vaccines are safe and effective for protection.

Chicago Public Schools has reported positive news regarding measles vaccination rates, with immunizations showing a welcome upward trend. After a prolonged period of decline, recent data indicates a promising increase, bringing the district closer to achieving community-wide protection against the disease. Health experts highlight the critical 95% vaccination rate needed to establish herd immunity and prevent outbreaks.
This improvement is particularly significant as measles was declared eradicated in the U.S. over two decades ago, but falling vaccination rates have led to resurgences nationwide. Kindergarten vaccination rates had previously dipped below the herd immunity threshold, raising concerns about a potential measles comeback. Chicago officials publicly voiced their concerns about low rates in some schools earlier in 2024.
City health leaders are celebrating the upward trend while acknowledging that their work continues. They are sending a clear message to parents: vaccines are safe, effective, and vital for protecting the community. This renewed focus on vaccination aligns with ongoing discussions by the Centers for Disease Control about childhood vaccine schedules.
