Trump urges shift in childhood vaccine recommendations, calls for splitting up MMR vaccine

President Donald Trump signed an executive order aimed at reshaping guidance on childhood vaccines, calling for federal support for 'maximal parental choice' and proposing to split up combined measles, mumps, and rubella (MMR) shots into single-disease doses. The order also recommends that all immunizations be administered during separate medical visits. The legislation was met with immediate pushback, including a rebuttal from GOP Sen. Bill Cassidy, who stated the President lacks expertise in the area.
