Fourth measles death in Pennsylvania marks record US toll as vaccinations decline
The nation records its highest measles death toll in decades, prompting HHS nominee to endorse vaccination while health secretary has downplayed the disease.
What to know
- The U.S. recorded four measles deaths in 2026, the highest toll in decades, as vaccination rates decline nationally.
- Measles cases hit record levels in 2026, surpassing any year since 1991; the nation is poised to lose its elimination status in November.
- HHS deputy secretary nominee Chris Klomp strongly endorsed MMR vaccination as essential to regain elimination status, but his boss, HHS Secretary Kennedy, is a longtime vaccine skeptic.
- Global measles is resurging; at least 19 countries have lost elimination status, and low-income countries account for 95% of the estimated 95,000 annual measles deaths worldwide.
“We've seen vaccination rates dropping all over the world, not just the United States.”

Chris Klomp, nominee for deputy secretary of HHS, testified before the Senate Finance Committee that the MMR vaccine is the most effective tool against measles and necessary to regain the U.S. elimination status.
“Unquestionably, the MMR vaccine is the single most effective public health tool that we have against measles. It's 97% effective after two doses to preventing transmission.”
