Pennsylvania has recorded its first measles-related deaths in 35 years — and both victims were unvaccinated. The two Lancaster County residents died amid a broader outbreak that has now reached 393 confirmed cases across 28 counties in 2026. The grim milestone underscores the real-world consequences of declining vaccination rates.
Pennsylvania is facing a stark public health wake-up call. The state confirmed two measles-related deaths on August 25 — its first in 35 years — both involving unvaccinated residents of Lancaster County. The Pennsylvania Department of Health did not release further details about the individuals, citing privacy concerns.
The deaths are unfolding against the backdrop of a significant measles resurgence in the state. So far in 2026, Pennsylvania has confirmed 393 measles cases spanning 28 counties, signaling a widespread and accelerating outbreak.

Why it matters: Measles was declared eliminated in the U.S. in 2000, making outbreaks of this scale — and fatalities — a serious warning sign. Both deaths involved unvaccinated individuals, reinforcing the critical role of the MMR vaccine in preventing not just infection, but life-threatening complications. Public health officials and clinicians may face renewed urgency to address vaccine hesitancy in their communities.
