Donald Trump signed an executive order on Monday calling for revamped childhood vaccine recommendations that would space out shots into separate medical visits, including splitting the MMR vaccine into three different shots. The order directs the nation’s health department to improve vaccine research and tells states with school vaccine mandates to consider changing their laws to match the administration’s advice.
The timing matters because Trump has spent years pushing the same idea, and he again put it plainly in the Oval Office on Monday, saying 1-year-olds should have their shots separated out into five separate visits. That detail does not fit neatly with the administration’s own plan, since separate MMR vaccines for children are not currently available in the United States, which leaves open how the recommendation could be carried out if it is adopted beyond the federal level.
The move also lands in the middle of a political fight over childhood vaccines and autism. Last December, Trump ordered HHS to review how peer nations approach vaccine recommendations and consider revising U.S. guidance accordingly, and the department later cut the number of vaccines it recommends for every child before that change was blocked in court. States, not the federal government, still have the authority to require vaccinations for schoolchildren, and polls show most Americans continue to support those requirements even as Republicans are less likely than Democrats to see them as important.
The bigger clash is that Trump and Kennedy keep linking autism questions to vaccines even though scientific consensus and decades of studies have concluded there is no link between childhood vaccines and autism. Trump recently pressed Health Secretary Robert F. Kennedy Jr. on the issue in a Cabinet meeting last month, asking, “How are you doing on the autism research?” Kennedy answered, “We will have an answer for you,” and on Monday he repeated his view that an unknown environmental factor is driving rising autism diagnoses.
That leaves Trump with a directive that changes the tone of federal vaccine advice but not the law that controls school requirements. The next test is whether HHS can turn the order into guidance that states will follow, or whether the administration’s latest push becomes another federal recommendation that collides with medical practice, court rulings and the limits of Washington’s power over school shots.
