President Donald Trump signs an executive order changing parts of the U.S. childhood vaccine recommendations. Multiple outlets report the order recommends separating the measles, mumps and rubella (MMR) combined vaccine into three individual shots given in separate visits. Several sources also describe the order as seeking to overhaul routine childhood vaccination recommendations and reduce the number of vaccines universally recommended.

The reported details center on what the order directs the federal public health process to do, rather than immediate changes to vaccines already in use. PBS NewsHour and other outlets cite a White House fact sheet, which also calls for improvements in vaccine research. Scientific American notes the decision to split MMR comes despite decades of research supporting the combined vaccine’s safety and effectiveness. Coverage differs mainly in emphasis—some focus on the schedule impact, others on broader shifts to national recommendations and research priorities.

Overall, outlets agree the executive order recommends fewer universally recommended childhood vaccines and specifically calls for dividing MMR into separate components administered during separate visits.
