President Donald Trump has signed an executive order proposing significant changes to the federal childhood vaccine schedule, sparking controversy by reviving unsubstantiated claims linking vaccines to autism amidst rising measles cases and ongoing scientific consensus.
President Donald Trump has revived a long-running political and scientific fight over childhood immunisation after signing an executive order on August 10 that would reshape the federal vaccine schedule and reintroduce claims about autism that have been rejected by decades of research. According to reporting by AP and Axios, the order presses the government to split the measles, mumps and rubella vaccine into three separate injections and to move several other routine childhood shots into narrower, risk-based categories.
The White House has framed the change as an effort to give parents and doctors more flexibility, building on an earlier administration review that said the United States recommends more childhood vaccines than some peer countries. That review, outlined in a May White House fact sheet and presidential order, directed the Centres for Disease Control and Prevention and its vaccine advisers to examine timing and sequencing, while public health experts say the latest move goes much further by turning that review into a direct push to alter long-settled guidance.
Medical groups reacted sharply. The American Academy of Paediatrics called the order “disheartening” and “dangerous”, while its president, Dr Andrew Racine, said there is no new evidence to justify major changes to childhood immunisation policy. AP reported that Republican Senator Bill Cassidy also criticised the plan, arguing there is no scientific basis for splitting the MMR vaccine, and vaccine specialists warned that adding extra appointments could raise costs, complicate access and make it harder for families to stay on schedule.
The order arrives as measles cases have surged and vaccine confidence has become more fragile, raising the stakes for any federal signal that could be read as endorsing doubt about established vaccines. AP said the administration’s action also comes amid broader efforts by Health Secretary Robert F. Kennedy Jr. to revisit routine childhood shots, including earlier proposals that faced court resistance, while the central claim linking vaccines and autism remains unsupported by extensive research involving millions of children.
