Trump Signs an Executive Order Cutting the Childhood Vaccine Schedule and Splitting the MMR Shot Into Three, and the Republican Chairman of the Senate Health Committee Calls It "a Stupid Thing to Do"
On August 10, 2026, President Trump signed an executive order titled "Delivering Gold Standard Childhood Vaccine Recommendations for Americans," standing alongside Health and Human Services Secretary Robert F. Kennedy Jr. The order directs the federal government to cut the list of diseases against which all children are universally recommended to be vaccinated — reporting put the change at 17 or 18 shots down to 11 — and states that the combined measles-mumps-rubella vaccine "should be administered in three separate single-disease shots once such products are domestically available," with childhood immunizations given at separate medical visits "to the maximum extent feasible." It also directs federal agencies to support litigation involving parental authority and religious exemptions to school-entry requirements. Trump repeatedly tied the changes to autism, a link that decades of research have not found. The sharpest congressional criticism came from a Republican: Sen. Bill Cassidy (R-La.), a physician who chairs the Senate Health, Education, Labor and Pensions Committee, posted on X the day the order was signed that "this executive order is wrong" and that "the President does not have the expertise to make these changes." Cassidy escalated on a Sunday show six days later, arguing the split MMR would turn two shots into six, six copays and six missed work days, and calling the policy "just a stupid thing to do" and "potentially tragic." Congressional Democrats — including the caucus's physician members — attacked the order as politics overriding science, with House Energy and Commerce ranking member Frank Pallone (D-N.J.) saying it "lets political appointees attempt to overrule decades of peer-reviewed science." Medical groups, including the American Academy of Pediatrics, said no new evidence justified the change and warned about timing: U.S. measles cases are at a 35-year high. States pushed back too. School vaccine requirements are set at the state level and are unaffected by the order; Pennsylvania said its guidelines would not change, Illinois Gov. J.B. Pritzker dismissed the order as "a thoughtless piece of paper," and the Governors Public Health Alliance said the order "circumvents that process and defies scientific consensus."
“Spreading out that vaccination schedule, I think, does make sense — [it gives] an infant human body the ability to actually absorb and deal with that rate of vaccination.”
