President Donald Trump has signed an executive order proposing to split the MMR vaccine into three separate shots and ease scheduling rules, prompting criticism from medical experts and contradicting scientific consensus.
President Donald Trump has signed an executive order that would split the combined measles, mumps and rubella vaccine into three separate injections and place all childhood immunisations on a looser schedule, a move that marks a sharp break from long-standing federal guidance and has already drawn forceful criticism from doctors. According to reporting by AP and Axios, the order was signed on August 10 and follows months of pressure from allies of Health and Human Services Secretary Robert F. Kennedy Jr., who has long questioned routine vaccine policy.
At the announcement, Trump repeated claims that giving several vaccines together could be harmful, including the idea that the MMR shot should not be administered as a combined dose. He argued that parents should instead make multiple visits so each vaccine is given separately, a change that would add appointments and likely complicate access for families. White House deputy chief of staff Stephen Miller framed the order as a challenge to what he described as industry influence over childhood medicine.
Medical experts say the administration’s approach runs counter to scientific consensus. AP reported that the current vaccine schedule has long been considered safe and effective, and the American Academy of Pediatrics continues to support combination vaccines because they reduce the number of injections while helping ensure children receive full protection on time. Critics also note that separating the shots could make it harder for parents to complete the schedule, especially for families who already face practical or financial barriers to care.
The order also comes amid a broader effort by Trump and Kennedy to reshape federal vaccine policy. AP reported that the administration has moved away from universal recommendations for some vaccines, including hepatitis B, COVID-19 and influenza, while the White House order in May directed the Centres for Disease Control and Prevention to review childhood vaccination timing and sequencing with an eye towards giving parents and doctors greater flexibility. Supporters say the changes are about choice; opponents say they risk reviving claims that have been repeatedly rejected by scientists.
