The President signed an executive order on August 10, 2026, directing the Department of Health and Human Services to revise the country's childhood vaccine guidance to align with practices used by comparable developed nations.
The White House said the order, which draws authority from the Constitution and federal law, follows a Presidential Memorandum issued on December 5, 2025. That earlier memorandum examined how U.S. core childhood vaccine guidance compares to peer developed countries.
The stated purpose is to bring American childhood vaccine recommendations into line with the best practices of those nations. The White House titled the order "Delivering Gold Standard Childhood Vaccine Recommendations for Americans."
