Pennsylvania Measles Cases: Two Unvaccinated Deaths Highlight Vaccine Gap
Two adults who had not received the measles‑mumps‑rubella (MMR) vaccine died from the disease in Pennsylvania, health officials announced.
The Commonwealth has counted 393 measles cases to date, and the United States has reported 2,777 confirmed infections in 2026, reaching the highest level in 35 years.
In Lancaster County, where the deaths occurred, only 85 % of kindergarten children are vaccinated—below the 95 % coverage needed for herd immunity.
"My deepest sympathies are with the families who are facing this unimaginable loss," Pennsylvania Secretary of Health Debra Bogen said.
She noted that long‑term elimination of measles has made the disease unfamiliar, heightening the risk of severe outcomes.
Officials urge the use of the MMR vaccine, which is 97 % effective in preventing measles in children aged one to six.
A recent Trump executive order calls for fewer childhood shots and proposes separating the MMR into three separate administrations—a change criticized by public‑health experts for potential confusion and cost.
Robert F. Kennedy Jr. has also pushed for vaccine schedule changes, many of which were blocked by a federal judge earlier this year. His mixed messaging on vaccine safety has contributed to growing vaccine hesitancy.
The U.S. may lose its status as a country that eliminated measles, a determination set to be reviewed by a federal panel in November. Canada lost its elimination status last year.
