虽然卡介苗接种是一种不安全的抗结核的保护方法,但每年仍有成千上万的婴幼儿被接种。严重并发症如全身性细菌播散较罕见,但局部并发症却十分常见。皮内接种卡介苗产生由注射部位的皮肤结节和区域淋巴结肿大组成的典型原发综合征。少数个体对细菌的反应是激烈的,并导致溃疡、淋巴结炎或化脓性淋巴结炎。如果菌苗皮下注射或受试者结核菌素试验阳性,这些并发症更易发生。若不经治疗,病损可持 Although BCG vaccination is an unsafe method of protection against tuberculosis, thousands of infants and young children are still being vaccinated each year.
