New Executive Order on Vaccine Policy Aims to Revise Childhood Vaccination Schedule and Challenge State Exemption Laws

President Trump signed an executive order on August 10, 2026, aimed at making significant changes to federal vaccine policy. The order directs major revisions to the childhood vaccination schedule, instructs care providers to administer monovalent vaccines as soon as available (starting with splitting the MMR vaccine), and pressures states to alter laws concerning religious exemptions for school entry requirements. The Executive Order also directs the U.S. Attorney General to challenge state laws conflicting with parental authority and mandates federal contractors and grantees to allow religious and medical vaccine exemptions.
