Pennsylvania Measles Deaths Spur Senate GOP Criticism Of Trump Vaccine Policies
Sen. Bill Cassidy on Wednesday blamed the Trump administration's vaccine policies for fueling a deadly measles surge after Pennsylvania reported four measles-associated deaths in 2026.[1]
Cassidy used a Senate Health, Education, Labor and Pensions confirmation hearing to call the outbreak "a terrible legacy" for the administration.[1] He singled out Health and Human Services Secretary Robert F. Kennedy Jr. for repeatedly linking vaccines to autism and warned that President Trump's August order to split the combined MMR shot into three doses will fuel hesitancy and endanger children.[1] Cassidy cited federal data showing more than 3,200 confirmed U.S. measles cases in 2026 during the hearing.[1]
Pennsylvania has recorded four measles-associated deaths this year: two infants in Lancaster County in mid-August, a 40-year-old unvaccinated Jefferson County woman, and an 18-year-old from Mifflin County who died of acute disseminated encephalomyelitis.[2] State tallies show roughly 676-693 cases across about 37-38 counties and roughly 100-124 hospitalizations in mid-September.[3] Officials say none of the four decedents were vaccinated and that the two infants were too young to be eligible for MMR under current guidelines.[2] At the same time, federal records show the CDC's National Center for Health Statistics has not yet received 2026 death certificates listing measles as the underlying cause, a discrepancy that has fueled a public debate.[4]
Early reporting emphasized disputes over how individual deaths were classified and whether state announcements matched federal death records.[4] More recent coverage and Republican criticism have recast the outbreak as a political indictment of the Trump administration's vaccine messaging and policy choices; Gov. Josh Shapiro has publicly accused Secretary Kennedy of stoking vaccine skepticism, and Kennedy has pushed back, saying he has offered aid and that he repeatedly supports MMR vaccination.[5]
