The Centers for Disease Control and Prevention should stop recommending a specific combination measles shot to young children, the Advisory Committee on Immunization Practices (ACIP) said on Sept. 18.

The CDC should recommend only the measles, mumps, rubella (MMR) vaccine, and not the measles, mumps, rubella, varicella (MMRV) vaccine—which also prevents chicken pox—for children ages younger than 4, ACIP said.
