RESEARCH OBJECTIVE: To evaluate the usefulness of immunization registry data to monitor provider compliance with CDC recommendations for conservation of pneumococcal conjugate vaccine (PCV) during the 2004 vaccine shortage. STUDY DESIGN: We used registry data from the Michigan Child Immunization Registry (MCIR) to evaluate changes in third and fourth dose PCV coverage in Michigan. Data for individual immunization records were obtained for a cohort of children enrolled in MCIR as of February 29, 2004. Vaccination data were collected through July 2004. The proportion of children who received DTaP3 and PCV3 at seven months of age was calculated for each birth month. The proportion who received MMR1 and PCV4 at sixteen months of age was also calculated. DTaP3 and MMR1 vaccine coverage was used for comparison as these vaccines were not in short supply during this time period and they are given at the same ages as PCV3 and PCV4, respectively. Coverage rates were compared between public and private providers and by practice specialty. POPULATION STUDIED: All children born between January 1, 2000 and February 29, 2004 were eligible for inclusion in the study. Over 600,000 children had at least one shot record and were included in the analysis. All public providers and 74% of private providers in Michigan supply vaccination data to the registry. PRINCIPAL FINDINGS: As of July 2004, 597,000 (94%) of 600,826 children in the registry had at least one shot record. Coverage for DTaP3 and MMR1 remained steady while PCV coverage declined at each time point when recommendations were announced. The sharpest decline was observed for PCV 3 at seven months of age when coverage dropped from 28% to 10% when recommendations to withhold the third dose were announced in March 2004. PCV coverage trends were similar for public and private providers as well as for pediatricians and family practitioners. CONCLUSIONS: Michigan immunization providers appear to be complying with CDC recommendations for PCV administration during the vaccine shortage. However, it is unknown if the third and fourth doses of PCV were not given by providers due to a shortage of vaccine or due to adherence to the guidelines. Additional information on variability of vaccine supply at the individual provider level would be needed to answer this question. IMPLICATIONS FOR POLICY, DELIVERY OR PRACTICE: Immunization registries can be useful in evaluating vaccination coverage trends during a vaccine shortage. These data may also be used to determine the extent to which children who had doses withheld during a shortage received those doses at a later date.
