卡介苗自一九二一年试用于人体作为结核免疫菌苗以来,已有六十年的历史。通过世界各国的长期使用观察,已公认是一种安全有效的预防结核病方法。我国解放三十余年来的使用和观察也证明了它的有效和安全性,而被定为当前我国防治结核病的一项重要措施。我国目前推广的接种方法主要有皮内、划痕两种,因而有两种不同浓度的菌苗。在实际使用中,如搞错菌苗接种途径,特别是高浓度误种或超剂量接种,均可引起局部强烈反应,一部分还会引起全身反应。由于预防接种常常是大批进行的,因此就很容易造成大批接种对象同时受累

As vaccination is often carried out in large numbers, it is easy to cause a large number of recipients to be affected at the same time
