President Donald Trump signs an executive order recommending that the MMR vaccine—currently given as a single combined shot protecting against measles, mumps, and rubella—be split into three separate shots administered at different times.
Doctors cited by both outlets say the proposal could create practical risks, including missed vaccination appointments. The standard approach delivers protection in one visit, and separating components would require additional scheduling and follow-through. ABC News frames the change as a question of why MMR is typically administered together and what separating it could mean for vaccination coverage. The New York Times emphasizes the medical community’s concerns that three-jab timing may reduce uptake and leave some people unprotected.
The two articles converge on the core points: the recommendation comes from Trump via an executive order, the split would replace the standard combined immunization, and medical experts warn it may increase the chance that people do not complete the series.
