The impact of public assistance factors on the immunization levels of children younger than 2 years.

OBJECTIVES: This study examined how children's immunization status varied with enrollment in the Women, Infants, and Children (WIC); Aid to Families with Dependent Children (AFDC); food stamp; and Medicaid programs. METHODS: A statewide survey was used to determine the percentage of children less than 2 years of age who were up to date for diphtheria, tetanus, and pertussis; polio; and measles, mumps, and rubella vaccines. RESULTS: WIC and uninsured children were more likely and AFDC and Medicaid children less likely to be up to date than others. CONCLUSIONS: The higher immunization status of WIC and uninsured children suggests that integrating immunization practices with government programs may be effective.
