Two die of measles in Pennsylvania; first US deaths in 2026

In Pennsylvania, two unvaccinated residents of Lancaster County have died from measles — the first such deaths in the state in 35 years and the first in the United States in 2026. Their passing arrives amid a spreading outbreak of 393 confirmed cases across 28 counties, a pattern that quietly reveals how the erosion of collective immunity can transform a preventable disease back into a lethal one. Public health officials are responding not only with grief for the families, but with a renewed call to the enduring covenant between communities and the vaccines that protect them.
