The Delaware County Health Department opened its back-to-school measles vaccination campaign on Monday in Upper Darby Township amid a growing number of measles infections across the state.

Through immunization clinics, online resources and the new mobile health clinic, Delaware County residents can get access to vaccines to protect themselves, their families and their communities against measles, the department said.

“Measles can be dangerous, and it is vital that Delaware County residents receive their MMR vaccines so that we can protect our most vulnerable populations,” said Lora Siegmann Werner, county health director.

A news release continues:

Measles is a highly contagious, viral respiratory illness. One person can spread measles to up to 18 other individuals. The virus spreads through breathing, coughing, or sneezing and can cause serious complications, sometimes leading to hospitalization.

Declining vaccination rates across the state have raised concern for measles and the DOH has confirmed 114 measles cases in Pennsylvania so far in 2026.

“Measles is a highly contagious, dangerous disease that can lead to serious issues, especially in children. But it is preventable through vaccination,” said Dr. Monica Taylor, Delaware County Council member and former council chair.

Delaware County residents can receive vaccines at their doctor or pediatrician’s office, local pharmacies, urgent cares and DCHD immunization clinics.
