Measles Deaths in Pennsylvania Highlight Rising Vaccine Hesitancy

Two residents of Pennsylvania who had not received the measles, mumps and rubella (MMR) vaccine have died from the virus, officials said. The state has recorded 393 measles cases this year, a 35‑year high reflected across the United States.

In Lancaster County—where the fatalities occurred—only 85 % of kindergarteners are vaccinated, falling short of the 95 % coverage needed for herd immunity. This gap endangers immunocompromised children and the wider community.

Governor Josh Shapiro spoke sternly at a news conference, calling the deaths “completely preventable.” He emphasized the essential nature of the MMR vaccine and urged residents to get vaccinated.

The United States recorded 2,777 confirmed measles cases in 2026 up to mid‑August, a rise from last year’s 2,289. California-led trends show higher aggression, influenced by growing vaccine hesitancy.

Late last month, President Donald Trump issued an executive order encouraging fewer childhood vaccinations and proposing a split of the MMR vaccine into three separate shots. Public health experts warn this could sow confusion about an already safe and effective vaccine.

Health Secretary Robert F. Kennedy Jr. has taken unprecedented steps to re‑schedule childhood vaccines earlier this year, some of which were blocked by federal court. His shifting stance on the MMR vaccine—a mix of endorsements and unverified safety claims—has amplified misinformation.

Shapiro highlighted a phone conversation with Kennedy in which he urged a halt to the misinformation and offered experts from the Centers for Disease Control and Prevention to assist. “Real life consequences arise from spreading misinformation,” Shapiro said.

The U.S. is at risk of losing its measles‑elimination status that will be reassessed in November. Canada lost this status last year, long before the U.S., signaling a shift in national health resilience that may ripple into climate‑adapted public health strategies.
