In August 2026, the U.S. administration issued an executive order setting out proposed federal policy for “Gold Standard Childhood Vaccine Recommendations.” It recommends, among other measures, separate measles, mumps and rubella shots and separate medical visits for childhood immunizations where feasible. The order directs an HHS task force to present plans within 90 days, including plans concerning single-antigen alternatives and vaccine timing and sequencing. The filing notes there are currently no approved U.S. monovalent measles or mumps or rubella vaccines.
