Trump's Push to Split MMR Revives Debate

President Donald Trump last week suggested separating combination childhood vaccines such as the measles‑mumps‑rubella (MMR) shot into individual doses, prompting immediate pushback from public‑health experts who warned the move would undermine decades of immunization practice, decrease coverage, and require new FDA approvals because measles‑only vaccines are not currently available in the U.S. Leading vaccine scientists (Dr. William Moss, Dr. Peter Hotez, Dr. Howard Markel and Dr. Walt Orenstein) said splitting MMR would create access barriers, increase clinic visits and risk outbreaks of measles and rubella.
