BACKGROUND. Pneumococcal conjugate vaccine immunization recommendations were rapidly implemented by primary care providers. Before the recommendations, concern was expressed that adding pneumococcal conjugate vaccine might result in delays in other vaccinations or preventive services.

OBJECTIVES. The study objectives were to measure whether incorporation of pneumococcal conjugate vaccine by primary care providers delayed other vaccinations or added primary health care visits.

DESIGN AND METHODS. In 2 counties surrounding Rochester and Nashville, we reviewed a representative sample of primary care charts for children born before and after licensure of pneumococcal conjugate vaccine. Receipt of vaccinations and health care visits were compared for the 2 age-matched cohorts.

RESULTS. We reviewed 1459 records from Rochester and 1857 records from Nashville. The pre–pneumococcal conjugate vaccine and post–pneumococcal conjugate vaccine cohorts had similar demographic characteristics. The median age for receipt of any vaccination was not older for the postvaccine cohort than for the prevaccine cohort in either community. The percentage of children up-to-date for vaccinations by 18 months for postvaccine versus prevaccine cohorts was similar in Rochester (72% in each cohort) and in Nashville (58% postvaccine and 65% prevaccine). The number of well-child care visits or other health care visits during the first 18 months of life was not statistically different between the 2 cohorts.

CONCLUSIONS. Implementation of pneumococcal conjugate vaccine was not associated with delays in other childhood vaccinations or more primary care visits.
