  1. Seroprevalence of antibody against poliovirus in inner-city preschool children : Implications for vaccination policy in the United States.

    Article - En anglais


    - To assess susceptibility to poliomyelitis in selected inner-city preschool children in the United States and to estimate the contribution of secondary spread of live attenuated oral poliovirus vaccine virus to type-specific immunity.


    - Cross-sectional seroprevalence study.


    - Serum neutralizing antibody levels against poliovirus types 1,2, and 3 were analyzed according to vaccination status, age, and other sociodemographic variables.


    - Hospital and satellite clinics serving inner-city populations in Houston, Tex, and Detroit, Mich, 1990 to 1991.


    - A total of 526 children aged 12 to 47 months seeking medical care were enrolled in the seroprevalence study ; 144 children aged 12 to 35 months without a history of previous oral poliovirus vaccination were enrolled in the secondary spread study.


    - Seropositive rates were similar in children in both cities, ranging from about 80% for types 1 and 3 in 12-to 23-month-old children to more than 90% in those aged 36 to 47 months.

    The most important predictor of seropositivity was the number of doses of oral poliovirus vaccine received (P<. 01), with levels approximately 90% for all 3 serotypes among children who had received 3 or more doses. (...)
