Trump signs order reducing recommended childhood vaccines from 18 to 11

The order affects federal immunization recommendations for approximately 3.6 million U.S. births annually and may influence state-level school vaccination requirements. Medical organizations including the American Academy of Pediatrics warn that spacing vaccines increases disease-transmission risk during the ongoing measles outbreak. Pharmaceutical development would be required to create individual measles, mumps, and rubella vaccines—currently unavailable in the U.S. market—potentially delaying availability. The policy shift redirects funding priorities and research protocols within HHS, and states retain legal authority to set their own school vaccination standards independent of federal guidance.
