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

President Donald Trump signed an executive order that aims to reshape childhood vaccine guidance, calling for federal programs to support maximal parental choice over these vaccines. The order recommends splitting up the combined measles, mumps, rubella (MMR) vaccine into three separate single-disease shots and having immunizations administered at separate medical visits. This directive faced immediate criticism, with GOP Sen. Bill Cassidy stating the executive order was wrong.
