    The population included 24268 children who had at least one immunization recorded in the health plan tracking system and had continuous health plan membership between 15 and 24 months of age in 1992 through 1993.

    The study group (N=4691) were those who had missed one or more of the immunizations due during their second year.


    Most 157%1 of the underimmunized children had made at least one clinic visit between 15 and 24 months of age.

    Among those underimmunized children who made well care visits, 90% had been partially immunized at the visit but had not been simultaneously given all vaccines for which they were eligible.

    When a provider did not give all possible vaccines simultaneously, there was a 9% chance that the child would go on to miss the remaining immunization.

    Simultaneous administration alone would have achieved full second year coverage of 30% of the underimmunized children in this population.

    Most underimmunized children (53%), including 35% of those children who had not made any well care visits, had made urgent visits between 15 and 24 months of age. (...)
