[Evaluation of the immunization coverage of young children in France. Results of surveys and methodologic analysis].

Twelve immunization coverage surveys were held in France between 1981 and 1986, for 24 to 59 month old children, using World Health Organization cluster survey methods. The results were comparable to those obtained with other evaluation methods, either exhaustive or using random samples. 80-96% of the children were immunized with BCG, DPT and Polio vaccines. Important variations are noted over a period of time and from one place to another for measles, rubella and mumps vaccines, so that further sustained effort is needed to reach rates high enough to reduce the incidence and complications of these diseases.
