Two unvaccinated residents of Lancaster County, Pennsylvania, have died from measles, the first U.S. measles fatalities of 2026, as the nation records its worst outbreak in more than three decades.
The Pennsylvania Department of Health confirmed both deaths, identifying the deceased only as residents of Lancaster County, a community roughly 60 miles west of Philadelphia. Neither individual had received the measles, mumps, and rubella vaccine, known as MMR. The deaths are the first measles fatalities in Pennsylvania in 35 years, a span during which the disease was considered largely eliminated in the state.
Pennsylvania Secretary of Health Dr. Debra Bogen issued a public statement urging residents to get vaccinated and acknowledging that decades without the disease have left many unfamiliar with its dangers.
"Because measles was largely eliminated in the Commonwealth for more than three decades, people are not familiar with this disease and don't fully understand the potential severity of the illness."
Bogen, a physician, added that the MMR vaccine "is safe and provides the best protection we have against measles."
The two deaths come against the backdrop of a national measles surge that has already shattered recent records. The Centers for Disease Control and Prevention recorded 2,777 confirmed cases across the country as of August 20, 2026. That figure exceeds last year's total of 2,289 cases, which was itself a record at the time, and marks the highest single-year count since 1991, when 9,643 Americans contracted the disease. The New York Post noted that the 1989, 1991 resurgence ultimately produced more than 55,000 infections and 123 deaths.
Pennsylvania alone has logged 393 cases across 28 counties this year. And the problem is not confined to one state. Maryland has declared a measles outbreak in three counties, with 31 total cases in 2026, 27 of them in unvaccinated residents. Iowa reported 17 cases of its own.
The pattern is consistent nationwide. Fox News reported that 93 percent of all measles patients in both 2025 and 2026 were either unvaccinated or had unknown vaccination status. Most cases have occurred in children and young adults between the ages of five and 19.
Measles is extraordinarily contagious. Nine out of ten unvaccinated people exposed to the virus will become infected. The CDC says two doses of the MMR vaccine, typically given at 12 to 15 months and again between ages four and six, reduce the risk of infection by 97 percent. But that protection only works at scale when at least 95 percent of the population is vaccinated, the threshold for what epidemiologists call herd immunity.
The United States is no longer meeting that threshold. The national kindergarten vaccination rate stands at 92.4 percent, below the 95 percent line. Vaccine exemption rates have climbed to 4.2 percent, up from 1.6 percent just over a decade ago. AP News reported that exemptions have reached an all-time high.
State-level numbers tell a mixed story. Pennsylvania's MMR vaccination rate sits at 94.6 percent, close to the herd-immunity line but still below it. Maryland is at 96 percent. Iowa lags at 90 percent.
Fox News senior medical analyst Dr. Marc Siegel framed the stakes bluntly:
"This isn't about personal choice, it's about community protection. We need to protect those who can't have a live virus vaccine because they are immunocompromised or pregnant."
Before the MMR vaccine became available in the 1960s, measles caused epidemics that killed an estimated 2.6 million people worldwide each year. National Review noted that in the United States alone, millions of cases occurred annually before 1963, with hundreds of children dying each year. By 2000, sustained vaccination had largely eliminated the disease from American soil.
Global deaths have fallen dramatically since the vaccine era began, to roughly 107,000 in 2023, but the virus remains dangerous. In otherwise healthy children, measles leads to pneumonia about 6 percent of the time. One in every 1,000 cases triggers brain swelling, or encephalitis. Of those who develop that complication, 15 to 20 percent die, and roughly 20 percent are left with permanent neurological damage, brain injury, deafness, or intellectual disability.
Just The News reported that nearly 20 percent of people who contract measles require hospitalization, and death occurs in one to three out of every 1,000 cases.
Those odds may sound small in isolation. But applied to nearly 2,800 confirmed U.S. cases, they translate into real hospitalizations, real complications, and now real deaths.
The outbreak has intensified scrutiny of the federal public health apparatus. National Review reported that measles cases have reached their 35-year high while Robert F. Kennedy Jr., widely known as the nation's most prominent vaccine skeptic, leads the Department of Health and Human Services. The publication noted that Kennedy's position raises questions about what role, if any, his leadership has played in the resurgence.
Whatever the cause, the numbers speak for themselves. A disease that the United States had functionally beaten a quarter-century ago is now spreading across dozens of states, and the vaccination coverage that once kept it in check has eroded year after year. The two deaths in Lancaster County are the sharpest reminder yet that measles is not a relic of the past.
State officials have not disclosed the ages, sexes, or any other identifying details about the two people who died. They have not said whether the two were connected to each other or part of the same transmission chain. The specific clinical cause of death, whether pneumonia, encephalitis, or another measles complication, has not been released. And Pennsylvania has not said whether it plans to declare a formal public health emergency in response.
Bogen expressed sympathy for the families but kept her public remarks focused on the vaccine message.
"We want to ensure every Pennsylvanian has the information they need to protect themselves, their loved ones and their communities."
Measles was a solved problem in this country for a generation. Two people in Lancaster County just paid the price for letting that solution slip.
