Multiple medical organizations, including the American Medical Association (AMA), have been barred from participating in the Centers for Disease Control and Prevention (CDC) vaccine advisory panels amidst significant restructuring led by Robert F. Kennedy Jr. This controversial move has drawn concern from former CDC advisers and leading medical groups, who warn that the integrity of vaccine policy is being compromised. Critics assert that the elimination of expert input risks undermining the scientific rigor necessary for safe vaccine recommendations. In response, Senate Democrats have initiated investigations into the implications of these changes, emphasizing the need for independent oversight in vaccine policy development. As the situation unfolds, calls for accountability and the preservation of scientific integrity within the CDC are intensifying.
