The tuberculosis morbidity rate in BGC-unvaccinated infants is 18 times greater than that in BCG-vaccinated infants and 6 times higher than the rate of complications due to BCG vaccination. If a scar due to BCG vaccination is absent or 1-2 mm, the tuberculosis morbidity in children of 3 years of life is 7 times higher than when a 3-mm or more scar has formed after vaccination. The technological failures are main causes of complications due to BCG vaccination. The type of a vaccine (BCG-1 or BCG-M) does not play a substantial role in the development of complications.
未接种卡介苗（BCG）的婴儿结核病发病率比接种卡介苗的婴儿高18倍，比卡介苗接种引起的并发症发生率高6倍。如果没有卡介苗接种留下的疤痕或疤痕为1 - 2毫米，3岁儿童的结核病发病率比接种后形成3毫米或更大疤痕时高7倍。技术失误是卡介苗接种引起并发症的主要原因。疫苗类型（BCG - 1或BCG - M）在并发症的发生中不起重要作用。
