Two residents of Lancaster County, Pennsylvania, have died after contracting measles, the state Department of Health announced Tuesday. Both individuals were unvaccinated, and their deaths represent the first measles fatalities reported in the United States in 2026 and the first in Pennsylvania since 1991.

State officials respond

Secretary of Health Dr. Debra Bogen expressed condolences to the families, saying, “My deepest sympathies are with the loved ones who are facing this unimaginable loss.” She added that, as a physician, she wants the public to understand that the measles‑mumps‑rubella (MMR) vaccine is safe and remains the best protection against the disease.

Outbreak numbers

To date, Pennsylvania has confirmed 393 measles cases across 28 counties in 2026. The outbreak is part of a broader national resurgence; more than 2,700 cases have been reported across the United States this year, surpassing any annual total since 1991. The disease was declared eliminated in the United States in 2000, yet the past 18 months have seen more cases than the previous 25 years combined.

Vaccine effectiveness

Health officials note that two doses of the combined MMR vaccine are about 97% effective at preventing measles infection. The agency has not released additional personal details about the deceased individuals, citing privacy concerns.

Public‑health context

The recent deaths underscore ongoing concerns among public‑health leaders about vaccine hesitancy and the importance of maintaining high immunization rates. While the measles virus is highly contagious, widespread vaccination has historically kept outbreaks limited. Experts warn that gaps in coverage can allow the virus to spread rapidly, especially in communities where vaccination rates fall below herd‑immunity thresholds.

What families can do

Parents and guardians are urged to verify that their children have received both recommended doses of the MMR vaccine, typically administered at 12‑15 months and again at 4‑6 years of age. Local health departments continue to offer free vaccination clinics and are working with schools and community organizations to improve outreach.

Looking ahead

Pennsylvania health officials say they will continue to monitor the situation closely, provide updates on case counts, and encourage vaccination as the most effective tool to protect individuals and the broader community.
