Coroner: Measles Killed 6-Week-Old Pennsylvania Baby

Diamantoni said "measles-associated" is not a category his office recognizes. On the newborn, he said his forensic pathologist "was quite adamant that it was not measles-related based on the size of the spleen, the lack of any inflammation, no fragility of the capsule around the spleen and the character of the laceration."

Shapiro responded on social media after the coroner's finding: "It's long past time for RFK to stop playing games with people's lives, report these deaths accurately on the CDC dashboard, and heed the guidance of actual medical experts so people get accurate information to discuss with their trusted health care providers and can best protect themselves and their children against this deadly disease."

Pennsylvania Health Secretary Dr. Debra Bogen wrote on X: "I again express my deepest condolences to the families who are grieving these losses," adding that the state has administered "a record number of MMR vaccinations in recent months."

Dr. Paul Offit, co-director of the vaccine education center at Children's Hospital of Philadelphia, said the coroner made the right call — even with the underlying disorder, the girl would not have died when she did without the virus. Offit also said the outbreak is being undercounted: "This outbreak is much bigger than people are claiming."
