Trump Signs New Executive Order To Reduce Childhood Vaccines And Alter MMR Schedule
President Donald Trump signed an executive order in the Oval Office on Monday, August 10, 2026, directing federal agencies to revamp childhood vaccine recommendations and to space shots into separate medical visits.[1]
The order recommends breaking the combined measles, mumps and rubella vaccine into three separate shots, even though individual measles, mumps and rubella vaccines are not currently available in the United States.[1] At the signing Trump said one-year-olds should have their shots spaced into five separate visits, though he did not specify which vaccines he meant.[1] The order tells the federal health department to expand vaccine research and to advise states with school vaccine mandates to consider updating laws, while leaving school-entry rules to the states.[1] It also instructs the Justice Department to press states to reduce the number of vaccines required for school attendance.[2]
In December the administration ordered Health and Human Services to review peer nations' vaccine approaches, and HHS then cut the number of recommended vaccines for every child — a change a court later blocked.[1] Similar attempts to alter the childhood schedule have been legally challenged before, and legal experts expect this order to face court fights as well.[2] At the signing Trump repeated a tie between vaccines and rising autism rates, a claim that extensive research has debunked.[2] The move was welcomed by vaccine critics and denounced by many public health experts.[2]
Public health officials warn the order comes amid a U.S. measles outbreak that could jeopardize the nation's measles elimination status as the school year begins.[1]
