瑞典自40年代后开始对新生儿、7岁和14岁的学生以及20岁的入伍军人普遍接种BCG。由于1972～1974年出生的婴儿接种BCG后骨关节病的发生率较高,因此自1975年4月起停止对新生儿作BCG普种。作者对1969～1984年发生瑞典儿童结核病作了分析,并比较了已经BCG免疫和未经BCG免疫的两组儿童的结核病发病率。结果表明,出生于瑞典和国外的0～4岁幼儿的结核病年发病率,1970～1974年为1.1例/10万,1975～1979年为1.3例/10万,1980～1984年增至2.1例/10万。
Since the late 1940s, Sweden has been routinely vaccinated with BCG for newborns, students aged 7 and 14, and veterans of 20 years. Because of the high incidence of osteoarthropathy in infants born between 1972 and 1974 after BCG vaccination, newborns were discontinued as BCG in April 1975. The authors analyzed Swedish children’s tuberculosis from 1969 to 1984 and compared the incidence of tuberculosis in both groups of children who had been immunized with BCG and who had not been immunized with BCG. The results showed that the annual incidence of tuberculosis in children aged 0-4 years old born in Sweden and abroad was 1.1 cases / 100,000 in 1970-1974, 1.3 cases / 100,000 in 1975-1979 and 2.1 cases in 1980-1984 /100,000.
