# Trump signs order to reshape childhood vaccine schedule, split MMR shots

President Trump signed an executive order aimed at overriding the CDC's recommended childhood vaccine schedule and breaking up the combined MMR shot into separate doses. The order, supported by Health Secretary Robert F. Kennedy Jr., seeks to limit childhood vaccines and could weaken established immunization protections. Public health experts warn that splitting the MMR vaccine and altering the schedule may reduce coverage and increase outbreaks, with legal challenges expected.
