Is the PRIORIX vaccine recommended for protecting against Rubella in the United States?

high confidence  ·  Last reviewed May 19, 2026

The Advisory Committee on Immunization has officially recommended the use of the PRIORIX vaccine for protection against measles, mumps, and rubella in the United States 4. This vaccine is part of the standard immunization schedule to prevent these viral infections and the serious complications they can cause, such as congenital rubella syndrome in newborns.

What the research says

The PRIORIX vaccine is a combined vaccine that protects against measles, mumps, and rubella 4. While global progress has seen many countries protect infants with rubella-containing vaccines, the specific recommendation for PRIORIX in the U.S. confirms its acceptance for these diseases 4. Research on similar combined MMRV vaccines, like the Priorix-Tetra, shows they are effective in preventing disease in children 6. Safety reviews of vaccines used in the United States confirm that the MMR vaccine does not increase the risk of autism and has a well-understood safety profile 5.
