The American Academy of Pediatrics on Tuesday released its annual childhood immunization schedule and, for the first time, urged that all children aged six to 23 months receive a Covid-19 vaccine. The guidance also calls for vaccination of children aged two and older who are at high risk for severe disease, live in long-term care facilities, or share a household with vulnerable individuals. The recommendation marks a rare split with the Centers for Disease Control and Prevention, which in May—under Health and Human Services Secretary Robert F. Kennedy Jr.—stopped advising routine Covid shots for healthy children. CDC guidance now leaves the decision to parents and physicians through a “shared clinical decision-making” model. AAP President Susan J. Kressly said the organization acted to provide “clear and confident” direction amid what it calls widespread misinformation. The divergence could complicate insurance coverage, because many payers and the federal Vaccines for Children program typically follow the CDC’s Advisory Committee on Immunization Practices. Pediatricians now face conflicting federal and professional advice just weeks before the respiratory virus season begins.
