President Donald Trump signed an executive order on Monday aimed at significantly reducing the number of universally recommended vaccines for children, cutting the list of essential shots from 18 down to 11. The move serves as a reinforcement of goals previously outlined by Health Secretary Robert F. Kennedy Jr., whose earlier attempts to overhaul the schedule were blocked in court. Under the new directive, several vaccinations including those for Covid, the flu, and hepatitis A and B would shift from universal recommendations to a model of shared clinical decision making between parents and physicians, while others would be reserved specifically for high risk groups.
Beyond changing which shots are recommended, the order suggests that immunizations be administered across separate medical visits rather than bundled together. This approach could potentially double the number of doctor appointments required for a child’s early healthcare, leading to increased costs and more time away from work or school for families. Most controversially, the order calls for splitting the combined measles, mumps, and rubella vaccine into three individual injections. While President Trump claimed during the signing ceremony that combined shots could be lethal and linked vaccines to autism—claims refuted by decades of scientific research—the CDC maintains that the current combination vaccine is very safe.
Medical professionals have reacted with alarm to the administration’s direction. Dr. Andrew Racine of the American Academy of Pediatrics warned that increasing the frequency of visits creates unnecessary barriers to vaccination. Pharmaceutical companies like Merck have also voiced concerns, noting that breaking up established combinations lacks evidence of benefit and could lead to missed doses. Even some Republican allies have distanced themselves from the move; Senator Bill Cassidy, a physician who helped confirm Kennedy as health secretary, stated that parents should trust their pediatricians over what he called an inaccurate executive order.
While officials argue that these changes provide parents with more choice and flexibility, critics say they undermine public health stability based on unfounded theories about infant immune systems. The American Academy of Pediatrics indicated it is currently evaluating legal options following this latest development. Meanwhile, Secretary Kennedy has been tasked with finding ways to make separate single dose vaccines available within ninety days, even though such products are not currently FDA approved or widely manufactured in the United States.
