The US Just Recorded Its First 2 Measles Deaths This Year

The United States recorded its first two measles-related deaths this year, both of which occurred among unvaccinated residents in Lancaster County, Pennsylvania. Lancaster County, known for its large Amish population, has seen a significant portion of the state's 393 measles cases so far in 2026, with nearly 20% of infected individuals requiring hospitalization.

Pennsylvania Governor Josh Shapiro described measles as a "serious and growing problem" across the country, emphasizing that illness and death from the disease is preventable with the available tools. Nationwide, there have been nearly 2,800 measles cases this year, up from 2,289 in 2025 and well above the 285 cases in 2023. The decline in vaccination rates across the nation is contributing to the current outbreaks.

The measles, mumps, and rubella (MMR) vaccine is highly effective, with a 97% efficacy rate if both doses are administered, and serious side effects are extremely rare. Pennsylvania Governor Josh Shapiro attributed the rise in measles cases to misinformation surrounding vaccination, noting that the state has held 91 pop-up vaccination clinics and administered over 4,100 vaccines this year.

Despite the efforts, measles has been traced to 28 counties throughout Pennsylvania, and the governor rejected suggestions that the problem is confined to a specific community. The recent surge has prompted President Donald Trump to sign an executive order aiming to "break up" the combined MMR vaccine, a move that has been criticized by over 210 medical organizations and patient groups for potentially leaving children less protected and families more confused.
