WASHINGTON (AP) — Newly installed Health and Human Services Secretary Robert F. Kennedy Jr. told agency employees that a commission formed by President Donald Trump will investigate the childhood vaccine schedule and other issues as a way to examine the rise in chronic diseases. The announcement on Tuesday raises questions about the promise he made during his confirmation hearings to Republican Sen. Bill Cassidy, a Louisiana physician. Cassidy harbored deep misgivings over Kennedy’s anti-vaccine advocacy, but said Kennedy had promised not to change the nation’s current vaccination schedule. Cassidy’s office did not respond to a request for comment.
