完全免疫(fully jmmunization)是指进行过全程基础免疫或在此基础上按期进行过加强注射而尚处于有效期内而言。这是人群对白喉免疫程度极重要指标,也是预防以至消灭白喉流行的关键性问题之一。据氏报告,苏联列宁格勒市对1-12岁儿童完全免疫率达95-97％,使1959年白喉发病率降为0.7/10万(比1952年下降127倍)。这说明了,广泛进行完全免疫已达到大大降低白喉发病率,是完全可能的。至于免疫对白喉带菌的影响,过去认为,应用类毒素进行白喉免疫,是抗毒素性,而不是抗菌性的,因此,只能起中和外毒素的作用,而
Fully jmmunization means that the whole course of the basic immunization has been completed or on the basis of which the booster injection has been carried out on a regular basis and still be in the period of validity. This is a very important indicator of the extent of the population’s immunity to diphtheria and one of the key issues in the prevention and even elimination of the prevalence of diphtheria. According to the report, Leningrad City, the Soviet Union, has a complete immunization rate of 95-97% for children 1-12 years of age, reducing the incidence of diphtheria in 1959 to 0.7 / 100,000 (127 times lower than in 1952). This shows that it is entirely possible that broad-based complete immunization has achieved a significant reduction in the incidence of diphtheria. As for the effect of immunization on diphtheria-carrying bacteria, it was previously thought that the application of toxoid for diphtheria immunization is antitoxic but not antibacterial, and therefore can only act as a neutralizing exotoxin and
