Trump signs order to revamp childhood vaccines, against medical groups’ guidance

US President Donald Trump on Monday signed an executive order calling for revamped childhood vaccine recommendations that promote his long-held but discredited theory that childhood vaccines should be spaced out into separate medical visits.The order advocates separating the measles, mumps and rubella (MMR) vaccine into three different single-disease shots and administering all childhood immunisations at separate appointments whenever possible.It also directs the nation’s health department to improve research on vaccines, which are already extensively studied, and present a plan to offer separate measles, mumps, and rubella vaccines for children, since that is not currently an option in the United States.
