Trump Vaccine Order Seeks Separate MMR Shots, Raising Major Hurdles
President Trump signed an executive order on Monday, August 10, 2026, calling for the MMR vaccine to be separated into three individual shots and for childhood vaccinations to be spaced out.[1]
The White House order directs federal agencies to pursue unbundling but cannot compel drugmakers to develop new single-antigen measles, mumps or rubella vaccines.[1] The order also does not change state school vaccine mandates, which remain set by state governments.[1]
There are currently no FDA-approved single-antigen measles, mumps or rubella vaccines in routine U.S. use, so reviving those products and building new manufacturing capacity would be required to carry out the order.[1] Industry officials and former regulators say designing, constructing and licensing new vaccine plants typically takes about five years and could require tens of millions of dollars in investment.[1]
Public health experts cited in the coverage say there is no scientific evidence that separating combination shots improves safety or effectiveness, and they warn the change would likely lower vaccination completion rates.[1]
