Notice to readers: updated recommendations of the Advisory Committee on Immunization Practices (ACIP) for the control and elimination of mumps.

On May 17, 2006, the Advisory Committee on Immunization Practices (ACIP) updated criteria for mumps immunity and mumps vaccination recommendations. According to the 1998 ACIP recommendations for measles, mumps, and rubella (MMR) vaccine, for routine vaccination, a first dose of MMR vaccine is recommended at ages 12-15 months and a second dose at ages 4-6 years. Two doses of MMR vaccine also are recommended for students attending colleges and other post-high school institutions. However, documentation of mumps immunity through vaccination has consisted of only 1 dose of mumps-containing vaccine for all designated groups, including health-care workers.
