President Donald Trump has signed an executive order related to childhood vaccines. The order calls for revamped recommendations that space out childhood shots into separate medical visits. This move promotes a theory that childhood vaccines should be administered separately, such as separating the measles, mumps, and rubella vaccine into individual shots.

The order also directs the health department to improve vaccine research and present a plan for separate measles, mumps, and rubella vaccines. Further details on the executive order and its potential impact are available from NBC 5 Dallas-Fort Worth.
