(Mary Conlon/The Associated Press)U.S. ‌President Donald Trump signed an executive order on Monday calling for fewer childhood vaccinations by limiting the inoculation schedule to 11 immunizations.The order also ​recommended splitting the childhood measles, mumps ​and rubella vaccine into three shots and delivering the shots at separate medical visits.U.S. Health Secretary Robert F. Kennedy Jr. ​had in January cut the U.S. immunization schedule to remove shots against six out of 17 diseases — a move halted ​by a federal court ruling. The Trump order says ⁠that the federal ⁠government will now only support the ‌remaining 11 shots. The American Academy of Pediatrics and vaccine-maker Merck criticized the order. Public health ​experts say the immunization schedule was based ⁠on decades of ⁠evidence showing the ‌vaccines could protect against serious illness and death, and that the number of shots reflect the specific health needs of Americans. They say reducing the ⁠recommended vaccines will leave more children vulnerable to preventable diseases.A nurse prepares to inoculate a child in Easley in March 2026.

The executive order reaffirms Kennedy's overhaul despite the ongoing litigation.
