President Donald Trump signed an executive order on Aug. 10 recommending that children be immunized against 11 diseases and that childhood vaccines, including the combined measles, mumps and rubella shot, be administered at separate visits.
For families booking back-to-school appointments this month, the immediate practical answer is that nothing at the pediatrician's office has changed. Separate measles, mumps and rubella vaccines are not licensed in the United States, a related federal schedule change remains blocked by a court, and pediatric professional societies have not altered their recommendations.
