DOH is proactively working with residents, community organizations, and health care providers to combat the measles outbreak in the Commonwealth through access to fact-based information and access to the measles, mumps, and rubella (MMR) vaccine.
State health officials have administered more than 5,300 MMR vaccinations at 165 pop-up vaccination clinics in the affected communities since the outbreak began in late April. Dozens of additional vaccine clinics are scheduled for the upcoming weeks and months, based on community interest and need. Overall, state health center staff have administered more than 7,900 MMR vaccine doses to residents across the Commonwealth in 2026.
Health care providers have also seen a surge of interest from residents seeking MMR vaccinations. In a typical month, Pennsylvania health care providers administer approximately 25,000 doses of the MMR vaccine. In August 2026, more than 49,000 MMR vaccines were administered across the Commonwealth and over the first three weeks of September 2026, more than 38,000 doses have been administered.
