Trump orders major changes — health experts warn of serious consequences.
President Donald Trump has signed a far-reaching executive order that would significantly change the federal government’s recommendations for routine childhood immunizations, while also directing the Justice Department to challenge certain state vaccination laws.
Healthcare organizations, pediatricians and vaccine manufacturers responded quickly, arguing that the changes are not supported by current scientific evidence.
Under the new order, the federal government now recommends routine immunization against 11 childhood diseases rather than the 18 previously included in the Centers for Disease Control and Prevention’s 2024 schedule.
Vaccines against COVID-19, seasonal influenza, rotavirus, hepatitis A, hepatitis B, respiratory syncytial virus (RSV) and meningococcal disease would no longer be universally recommended. Instead, they would be reserved for children considered at elevated risk or handled through shared decision-making between families and physicians.
Policy also calls for separating the combined measles, mumps and rubella (MMR) vaccine into three individual injections administered during different medical appointments.
Legal challenge aimed at states
Beyond medical recommendations, the executive order instructs the attorney general to challenge state laws that the administration believes conflict with parental rights, religious freedom, disability protections and access to religious or medical exemptions from vaccination requirements.
School vaccination mandates, however, remain largely under state authority, meaning the federal order does not automatically change existing state requirements.
Leading medical organizations criticized the order shortly after it was announced.
According to Reuters, the American Academy of Pediatrics warned that the changes are likely to create uncertainty among parents while delaying childhood immunizations. Medical experts also reiterated that decades of research have found no evidence linking vaccines to autism.
Several organizations, including the Infectious Diseases Society of America and the National Foundation for Infectious Diseases, argued that reducing routine recommendations could leave more children vulnerable to preventable illnesses.
Limited immediate impact
Although the executive order outlines a major policy shift, many practical aspects remain unchanged for now.
Parents may still request vaccines placed under the shared clinical decision-making category, while the White House said the Vaccines for Children program—which provides free immunizations for eligible families—will continue operating.
Major insurers, including Blue Cross Blue Shield and CVS, also indicated they will continue covering CDC-recommended childhood immunizations while reviewing the administration’s new policy.
Some proposals cannot be implemented immediately. Standalone measles, mumps and rubella vaccines are not currently licensed or available in the United States, meaning the recommendation to separate the MMR vaccine cannot yet be carried out.
Federal health officials said they will work with manufacturers over the next 90 days to explore potential options.
Executive order revives a vaccine policy promoted earlier this year by Health Secretary Robert F. Kennedy Jr. That earlier effort was halted by a federal court before taking effect.
Administration officials have argued that the United States recommends more childhood immunizations than many comparable countries. Public health experts dispute that characterization, noting that vaccination schedules vary internationally based on disease prevalence, healthcare systems and population needs, and that the previous U.S. schedule was broadly comparable with several other developed nations.
