title: Immunizing California's children. Effects of current policies on immunization levels.
abstract: Data collected by the Immunization Unit of the California Department of Health Services from 1979 to 1987 were analyzed to determine the effects of changes in state policy on the immunization levels of children in California. By December 1986, 90% of all children entering kindergarten in California were adequately immunized, representing a 15% increase from 1979. Although California has shown substantial improvements, it still lags behind the national weighted average. Even with high levels of immunization at kindergarten entry, many toddlers of 7 months and 2 years old remain inadequately immunized. Children immunized solely in the private sector were more adequately immunized than those served by public health clinics; the public-private difference for infants aged 7 months was nearly twofold.
