Overview
- On Sunday, Aug. 23, CMS administrator Dr. Mehmet Oz told CBS’s Face the Nation that the measles‑mumps‑rubella vaccine is “not a lethal vaccine,” directly contradicting President Trump’s earlier on‑record suggestion that the combined shot could be dangerous.
- Earlier this month the president signed an executive order directing HHS to pursue offering measles, mumps and rubella as separate vaccines and asking the Justice Department to press states on school‑entry rules.
- Public‑health groups, fact‑checkers and the CDC have said the MMR is very safe and that no major scientific organization supports unbundling the combined vaccine.
- Manufacturers and regulators say separate single‑antigen MMR products are not licensed in the United States and would require new trials, FDA review, and years of work with Merck estimating roughly a decade before separate shots could be widely available.
- CDC data show kindergarten MMR coverage near 92%, below the ~95% threshold for herd immunity, and experts warn that mixed federal messages and state resistance could worsen vaccine hesitancy and raise outbreak risk.
