Trump pushes three-shot MMR plan and separate-visit vaccine schedule

President Trump signed an executive order to overhaul the childhood vaccination schedule by challenging CDC guidance, proposing that the MMR vaccine be split into three separate shots and that vaccines be given at separate visits; it also moves several vaccines into high-risk or ‘shared clinical decision-making’ categories and empowers the attorney general to challenge conflicting state laws. The order has no immediate legal effect on the public and faces criticism from health experts who note vaccines are safe and do not cause autism, while noting that school vaccine requirements are set at the state level.
