title: [Evaluation of BCG vaccination programme based on results of the Third Nationwide Tuberculosis Survey].
abstract: Evaluation of BCG vaccination programme had been carried out by means of re-analyzing the results of the Third Nationwide Random Sampling Survey for Epidemiology of Tuberculosis conducted in 1990. The BCG vaccination coverage among children under 4 years was 65.0% in 1990. It was lower than other reports in the past. The positive rate of tuberculin testing among children under 4 years who had the history of BCG vaccination was only 26.3%. City had the highest rate of 55.8%. The fact indicated the unsatisfactory quality of BCG vaccination in the country. The factors inducing such a lower positive rate should be clarified and overcome as soon as possible in the near future. The protective effect of BCG vaccination for children under 4 years was apparent but it was not in 5-9 age group. In this connexion, the investigation and study on the necessity of re-vaccination among primary school entrants should be conducted.
