由于麻疹减毒活疫苗的广泛应用,麻疹被动免疫日渐稀少。但暴露于麻疹后的易感儿童仍应给予免疫球蛋白(Ig)预防,如在暴露后5～6天内给予足量的Ig,可防止麻疹及相关疾病发生;若剂量不足或在潜伏期后给予,虽可减轻疾病但不能防止发作。作者评价了暴露于麻疹后按推荐剂量预防性应用Ig的临床效果。
Due to the wide application of live attenuated measles vaccine, measles passive immunization is increasingly scarce. Susceptible children after exposure to measles should still be given immunoglobulin (Ig) prophylaxis. For example, adequate Ig should be given within 5-6 days after exposure to prevent measles and related diseases; if the dose is insufficient or given after the incubation period , Although it can reduce the disease but can not prevent the attack. The authors evaluated the clinical effect of prophylactic Ig administration at the recommended dose after exposure to measles.
