天津市到1956年六月底,皮内接种485,061人,八周后复查平均阳转率为95.7％;口服接种7.267人平均阳转率为76.0％;划痕接种20,761人平均阳转率为93.4％。根据几年来的工作情况,我们体会到三种接种法的优缺点如下:1.皮内接种法:优点——结素阳转率高,剂量准确,费用低廉(每人菌苗费用为3分)缺点——①技术操作比较困难,尤其是婴儿皮肤极薄嫩,很难做到满意的皮内注射。②合併症多,据1954-1955年间接种204,290人的统计,接种后四星期淋巴结腫大
In Tianjin, by the end of June 1956, 485,061 people were inoculated in Pinyin, and the average rate of positive conversion was 95.7% after 8 weeks. The average positive conversion rate of oral inoculation of 7.267 people was 76.0%. The average positive conversion rate of 20,761 people who were inoculated with scratches was 93.4% . According to the work of the past few years, we understand the advantages and disadvantages of the three vaccination are as follows: 1. Inoculation method: Advantages - high rate of positive tuberculin, accurate dosage, low cost (cost per vaccine is 3 ) Disadvantages - ① technical operation is more difficult, especially the infant skin is very tender, it is difficult to achieve satisfactory intradermal injection. ② more complications, according to 1954-1955 years of inoculation 204,290 statistics, four weeks after inoculation of lymph nodes
