A Preventable Crisis Turns Fatal
Pennsylvania has now recorded four measles-associated deaths in 2025 — the first in the state in 35 years — as a growing outbreak spreads across 38 counties and federal health officials actively undermine the public health infrastructure designed to stop exactly this kind of catastrophe.
The Mifflin County Coroner’s Office confirmed this week that an 18-year-old resident died from acute disseminated encephalomyelitis (ADEM), a rare and severe neurological complication of measles. The Pennsylvania Department of Health simultaneously confirmed a separate measles-associated death in Jefferson County. Both individuals were unvaccinated.
“My thoughts are with the two families who lost loved ones to this highly contagious virus, as Pennsylvania faces the worst measles outbreak in more than three decades,” said Secretary of Health Dr. Debra Bogen. “We remain committed to working with our partners across Pennsylvania to stem this outbreak and prevent more deaths.”
Nearly 700 illnesses have been reported statewide this year, with roughly 100 new cases emerging in just the last seven days. The United States is enduring its worst year for measles since 1991, and has now recorded seven measles-associated deaths in two years — more than the combined total over the previous three decades.
The Four Deaths: What We Know
The four Pennsylvania deaths span three counties and represent a cross-section of the unvaccinated population most vulnerable to measles and its complications. Two infants died in Lancaster County in August; they were too young to have received the MMR vaccine under current medical guidelines. A 40-year-old woman died in Jefferson County on September 12. And the 18-year-old in Mifflin County died from the neurological complication ADEM, a condition that illustrates how measles does not simply produce a rash and resolve — it can destroy brain tissue and kill otherwise healthy young people.
The state Department of Health confirmed that none of the four victims had been vaccinated, and said it would not release additional identifying information out of respect for the families’ privacy. The coroner’s office ruled all deaths natural in manner, caused directly by measles complications.
How America Got Here: Decades of Erosion, Accelerated by Policy
The United States eliminated domestic measles transmission in 2000, a landmark public health achievement built on decades of sustained, high vaccination rates. That achievement required maintaining coverage above 95% across the population — the threshold necessary to protect those too young or too medically vulnerable to be vaccinated themselves. Coverage has since fallen below that level, and the consequences are now visible in hospital wards and coroners’ reports.
The erosion has multiple causes. Parental vaccine waivers have grown more common. Healthcare access in rural and low-income communities remains inadequate. And a years-long campaign of disinformation — amplified across social media and, increasingly, from within government itself — has corroded public trust in one of medicine’s most thoroughly validated interventions.
More recently, the Trump administration has accelerated that erosion in ways that have no modern precedent. Health Secretary Robert F. Kennedy Jr., who built a public profile on vaccine skepticism and conspiracy theories, has used the nation’s top public health platform to cast doubt on vaccine safety. Federal funding for local vaccination outreach has been cut. And according to Pennsylvania Governor Josh Shapiro, Kennedy personally intervened to prevent the CDC from reporting the Pennsylvania measles deaths — apparently because the death toll contradicts the narrative his department has been promoting.
Governor Shapiro Names the Problem Directly
“This serious situation continues to be made worse by RFK Jr. playing games with public health and safety,” Shapiro wrote on X following the announcement of the two newest deaths. “It’s long past time for Secretary Kennedy to stop stoking vaccine skepticism and misinformation and compromising the serious mission of the nation’s public health agencies.”
The governor’s accusation about CDC reporting is particularly grave. If accurate, it means a sitting cabinet secretary suppressed epidemiological data during an active outbreak — not to protect privacy, but to protect a political position. That is not a bureaucratic dispute. It is a direct threat to the transparency that allows communities, clinicians, and parents to make informed decisions during a public health emergency.
Kennedy’s record on vaccines is not a matter of legitimate scientific debate. The MMR vaccine is safe, effective, and has prevented millions of deaths globally. Framing his position as one side of a reasonable disagreement would be false balance — and, given the body count now accumulating in Pennsylvania, a dangerous one.
What Measles Actually Does
Measles is not a benign childhood illness. It is one of the most contagious pathogens known to science, capable of remaining infectious in the air or on surfaces for up to two hours after an infected person has left the room. Nearly 20% of measles cases result in hospitalization. Between one and three per 1,000 cases result in death — a rate that sounds small until you apply it to hundreds of cases in a single state in a single year.
The virus spreads through breathing, coughing, and sneezing. Early symptoms — fever, cough, runny nose, red and watery eyes — can take between 7 and 21 days to appear after exposure, giving the virus ample time to travel undetected through households, schools, and religious communities. The characteristic rash appears days later, starting at the head and moving downward. By then, transmission has often already occurred.
Complications include pneumonia, encephalitis, and ADEM — the condition that killed the 18-year-old in Mifflin County. In infants, the immune suppression caused by measles infection can persist for years, leaving children vulnerable to other diseases long after the rash clears.
The Stakes Are Now International
In November, international health officials will convene to determine whether the United States and Mexico have lost their measles-free status — a designation earned through sustained public health effort and now at serious risk of being revoked. Losing that status would carry both symbolic and practical consequences, affecting travel advisories, international health cooperation, and the country’s credibility as a leader in global disease prevention.
The MMR vaccine, Dr. Bogen noted, “kept measles outbreaks at bay for decades.” It is still available. It is still free in most settings. It still works. The deaths in Pennsylvania were not inevitable — they were the predictable result of declining vaccination rates, inadequate healthcare access, and a federal health apparatus now actively working against the public it is meant to serve.
