Beginning June 1, 2026, the Johnson County Department of Health and Environment will transition all walk-in immunization services from its Mission clinic to its Olathe location.

This change allows the department to streamline services, support staff availability and continue providing high-quality vaccine services for the community.

Also starting June 1, 2026, the Olathe walk-in immunization clinic will extend its hours on Fridays to better serve the community. Immunizations will be available Monday-Thursday from 8 a.m. to 4 p.m. and Fridays from 8 a.m. to 2 p.m. at 11875 S. Sunset Dr., Suite 300, in Olathe.

The Mission WIC office will remain open, and WIC services there will continue without interruption.
