Getting Shots on Time: Children are receiving their shots on time in San Bernardino County, Calif., as a result of implementing the immunization registry with its reminder/recall function. The San Bernardino registry conducted a study on the average age in months for children completing either selected immunizations or series completion before and after implementation of their registry. The registry had a major impact on the average age at which a child receives the MMR vaccine, a one-dose shot due at 12 to 15 months of age. In 1992, the average age for receiving an MMR vaccine was 33 months. In 1999, after the implementation of the registry and the reminder/recall function, which returns children to their providers for immunizations (and most likely other well-child services); the average age was 13 months. A clear correlation was established: the more recent the birth cohort, the earlier the age in months in which that cohort received immunizations.
