Donald Trump asked his health secretary "How are you doing on the autism research?"

President Donald Trump is set to sign an executive order Monday that would overhaul federal recommendations for childhood vaccines, backed by his view that immunizations should be given individually rather than in combinations, according to a White House fact sheet. The order calls for the measles-mumps-rubella vaccine to be given as three separate shots and directs health officials to expand vaccine research. Public health experts warn that spreading out doses leaves children vulnerable to preventable illness longer. States, not Washington, set school vaccine requirements. The announcement follows a Cabinet meeting in which Trump publicly asked Health Secretary Robert F. Kennedy Jr. for an update on autism research; Kennedy replied that an answer would come. Decades of research have found no link between vaccines and autism. The move comes amid a measles outbreak that may cost the U.S. elimination status.
