  1. Persistent low immunization coverage among inner-city preschool children despite access to free vaccine.

    Article - En anglais

    Objective

    To compare vaccination coverage among children 19 to 35 months of age from public housing developments where a free vaccine outreach program was in place with children residing elsewhere in the city.

    Design

    A household survey using a multistage cluster sampling method to compare community areas which accounted for 80% of measles cases during 1989 (high-risk stratum), areas which accounted for the remaining 20% of cases (low-risk stratum), and public housing developments (public housing stratum) having free, on-site vaccination services.

    Setting

    Inner-city Chicago households, April to May 1994.

    Outcome Variables

    Antigen-specific and series-specific coverage based on written records.

    Results

    Based on evaluation of 1244 children, city-wide coverage for four doses of diphtheria-tetanus-pertussis vaccine, three doses of polio vaccine, and one dose of measles-containing vaccine (4 : 3 : 1) was 47% [95% confidence interval (CI), 40% to 55% ]. Coverage was significantly lower among children residing in public housing (23% ; 95% CI, 18% to 28%) compared with those residing in high-risk strata (45% ; 95% CI, 38% to 52%) and low-risk strata (51% ; 95% CI, 43% to 60%). Compared with white children (53%), coverage for the 4 : 3 : 1 series was lower among African-American children in public housing (29%) or outside public housing (36%). Moreover, 11% (95% CI, 8% to 14%) of children residing in public housing had never received any immunizations.

    Conclusions
