President Donald Trump has issued an executive order to overhaul the federal childhood vaccine schedule, triggering controversy with medical experts and states over delays, costs, and implications for disease control amidst rising measles cases.
President Donald Trump has ordered a major rewrite of the federal childhood vaccine schedule, setting up a clash with paediatricians, public health officials and states that have long relied on CDC guidance. The move, announced on Monday, would split the combined measles, mumps and rubella jab into three separate injections at three separate appointments and narrow the number of diseases covered by routine federal recommendations. White House material from May said the administration was already seeking to realign U.S. vaccine policy with what it called best practices in other developed countries.
Trump and Health Secretary Robert F. Kennedy Jr. used the signing to repeat the disputed claim that the MMR vaccine causes autism, even though the order itself does not say that. The medical consensus remains unchanged: large studies and repeated reviews have found no link between routine childhood vaccination and autism, while the 1998 paper that first fed the claim was later retracted after investigators found falsified data. The administration’s new order still recommends the MMR shot, but only as three doses rather than one combined vaccine.
The practical effect of the change could be far-reaching. Under the new framework, vaccines that children once received together in a single visit would be split across multiple appointments, raising the prospect of extra co-payments and more missed doses. The American College of Physicians has warned that the approach could increase out-of-pocket costs, while paediatric groups say the existing schedule is designed around how children’s immune systems develop and when they are most at risk from infection.
That warning lands at a sensitive moment. Measles has already spread widely across the United States this year, with more than 2,300 cases reported, and public health officials are weighing whether the country may have lost its elimination status. Andrew Racine, president of the American Academy of Pediatrics, said the order ignored the medical basis for the current timetable and argued that delaying or spacing out vaccines would leave children more exposed as measles continues to circulate.
The order also directs the attorney general to challenge state laws that, in the administration’s view, do not properly protect religious exemptions and parental rights. It comes amid a wider disruption to federal vaccine governance, after Kennedy’s push to reshape policy helped stall the CDC’s advisory process. The agency has not yet said whether it will adopt the new framework, reject it or stay silent, leaving doctors, insurers and states to work out whether the federal schedule and clinical guidance will now point in different directions.
