Americans express greater confidence in federal career scientists and independent medical groups than in the political leaders running U.S. health agencies, and they are more likely to accept vaccine recommendations from the American Academy of Pediatrics than from the Centers for Disease Control and Prevention, according to a University of Pennsylvania survey.

Kennedy Jr.’s long-standing effort to reshape pediatric vaccine policy.
