当前推行的卡介苗预防接种,在接种前常需用结核菌素试验来选择对象。我地区地处边陲,条件较差。而结核菌素有效期短(出厂后一个月),运输及保存均需冷藏,所以卡介苗普种工作受到了限制。有谓可用灭活卡介苗代替旧结核菌素者。为验证其实用价值,我所于1982年6～11月间进行了测试对比观察,现将结果报告于下。一、对象及方法观察对象包括7～14岁儿童共500人,全部对象随机分配为A、B、C三个组。三组观察对象均于左右两前臂同时分别
The current implementation of BCG vaccination, often need to use tuberculin test before selection to select the target. I am located in the border area, poor conditions. The tuberculin short period of validity (one month after delivery), transportation and preservation are required to refrigerate, so BCG universal work has been limited. It is said that inactivated BCG can be used instead of the old tuberculin. To verify its practical value, I conducted in 1982 to November 1982 comparative test observations, the results are reported below. First, the object and method The observation object includes a total of 500 children aged 7 to 14, all subjects were randomly assigned to A, B, C three groups. Three groups of observers were both left and right forearms at the same time, respectively
