Challenges in Separating the MMR Vaccine into Individual Shots

Immunizations for measles, mumps, and rubella are not available as separate injections. Experts have found no evidence to support dividing the vaccine into three individual doses. The combined measles-mumps-rubella (MMR) vaccine has been administered in the U.S. for decades as a single shot.

Dividing the MMR vaccine into three separate shots would be costly and time-consuming. Vaccine experts predict that it would likely cost millions of dollars and require several years to implement this change. This challenge makes it impractical to adhere to any directive proposing three separate doctor visits for the vaccines.
