Pennsylvania has reported two measles-related deaths in Lancaster County, marking the state's first fatalities from the disease in 35 years.
The deaths come as the county remains at the center of a major outbreak that has affected nearly 400 people across 28 counties this year.
The MMR vaccine provides about 97% protection against measles after the recommended doses. Health officials emphasise that high vaccination coverage is critical because measles is highly contagious and can cause serious complications, including pneumonia and brain swelling.
Pennsylvania currently has the third-highest number of measles cases in the United States this year.
Health Secretary Dr. Debra Bogen expressed condolences to the affected families and urged residents to take measles seriously. The World Health Organization estimates that about 95% community vaccination coverage is needed to maintain herd immunity and prevent sustained outbreaks.
