    Article - En anglais

    Objectives 

    To determine immunization coverage of infants receiving Medicaid in Tennessee and to identify risk factors for failure to complete recommended vaccinations by 24 months of age.

    Design 

    Retrospective cohort study.

    Subjects 

    A total of 33 615 children born in one of three urban Tennessee counties from 1980 through 1989 who were enrolled in Medicaid throughout their first 24 months of life.

    Main Outcome Measures 

    Receipt of four diphtheria-tetanus-pertussis, three oral polio, and one measles-mumps-rubella vaccines by 24 months of age (up-to-date), as recorded in computerized county immunization records and Medicaid billing files.

    Results 

    Overall, 45% of infants enrolled in Medicaid in the three urban counties completed the recommended vaccinations by 24 months.

    The only strong independent predictors of immunization completion were number of prior births for the mother, timing of the first immunization, and county of birth.

    The proportion up-to-date was 56% for first-born children compared with 27% for those whose mothers had at least three prior births ; 55% for those whose first immunization was on time compared with 22% for those with a delay in the first immunization ; and 63%, 52%, and 37% for infants born in the three respective counties.

    Conclusions 

    Of infants born in the three counties in the 1980s who were enrolled in the Tennessee Medicaid program, fewer than half completed their recommended childhood vaccinations by 24 months of age.
