Tuesday, August 11, 2026 - President Donald Trump has signed an executive order directing the U.S. government toward a narrower childhood vaccination schedule, reducing the number of vaccines routinely recommended for all children from 17 to 11.
The order also calls for vaccines to be given at separate medical visits when feasible and supports splitting the measles, mumps and rubella (MMR) combination vaccine into separate shots. The move represents a major shift in federal vaccination policy and follows months of efforts by the Trump administration to overhaul childhood immunization recommendations.
Medical organizations and public-health experts have strongly criticized the changes, warning that they are not supported by the evidence behind the established vaccination schedule.
The American Academy of Pediatrics and other medical groups have opposed the administration’s approach, while experts have specifically rejected claims linking childhood vaccines to autism.
The controversy comes as U.S. vaccination rates have declined and measles has returned as a significant public-health concern, raising fears that reduced protection could make preventable outbreaks harder to contain.
The order is likely to trigger an intense fight over federal health policy, parental choice and the authority of states to set school vaccination requirements. States retain significant control over school-entry vaccine mandates, meaning the federal changes will not automatically produce identical rules nationwide.
For parents, doctors and public-health officials, the immediate challenge is navigating the changing recommendations while ensuring children remain protected against serious infectious diseases.
