States that enact school vaccine requirements are advised to consider the Gold Standard Childhood Vaccine Recommendations and consider updating their laws to reflect the recommendations. By signing today’s Executive Order, President Trump is reaffirming his commitment to gold standard science, ensuring Americans receive the best possible medical advice, and empowering patients and doctors with maximum flexibility. The strategy prioritized development of a vaccine framework that ensures America has the best childhood vaccine schedule. In December 2025, President Trump signed a Presidential Memorandum beginning the process to align U.S. core childhood vaccine recommendations with best practices from peer, developed countries. In May, President Trump signed an Executive Order realigning United States core childhood vaccine recommendations with best practices from peer, developed countries.
