从第三次流调结果探讨我国卡介苗接种工作

通过对全国第三次结核病流行病学调查资料的再次分析来评价我国卡介苗接种工作。分析结果表明１９９０年调查时０～４岁儿童的卡介苗接种率为６５．０％，低于以往报道。０～４岁有卡介苗接种史儿童的结素阳性率仅为２６．３％，城市的阳性率最高也仅５５．８％，表明接种质量不高，必须找到原因而迅速改进。我国目前卡介苗接种的保护效果对０～４岁儿童是明显的，但对５～９岁儿童即不明显，因此必须进一步调查研究卡介苗复种的必要性。

Evaluation of BCG vaccination programme based onresults of the Third Nationwide Tuberculosis Survey

valuation of BCG vaccination programme hadbeen carried out by means of reanalyzing the resultsof the Third Nationwide Random Sampling Survey forEpidemiology of Tuberculosis conducted in 1990. TheBCG vaccination coverage among children under 4years 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 historyof BCG vaccination was only 26. 3%. City had thehighest rate of 55. 8%. The fact indicated the unsatis-factory quality of BCG vaccination in the country. Thefactors inducing such a lower positive rate should beclarified and overcome as soon as possible in the nearfuture. The protective effect of BCG vaccination forchildren under 4 years was apparent but it was not in59 age group. In this connexion, the investigationand study on the necessity of revaccination among pri-mary school entrants should be conducted.
