目的：为了解南通市人群白喉抗体水平，合理制定免疫接种计划提供科学依据。方法：采用锡克氏试验、间接微量血球凝集试验进行人群白喉免疫水平调查。结果：人群锡克氏试验阳性率14．15％，6岁以下儿童均在10％以下，10岁以上年龄组均在10％以上，20～40岁组在20％以上。人群白喉抗体阳性率54．28％。接种组与未接种组，全程接种组与本全程接种组之间均有显著差异。结论：在目前基本无白喉病例的情况下，人群对白喉的免疫力主要来源于人工免疫。目前在计划免疫工作中必须全程接种才能保证免疫效果，同时要注意成人的预防接种工作，提高整个人群的免疫水平。
Objective: To understand the level of diphtheria antibodies in Nantong population and to provide a scientific basis for the rational formulation of immunization programs. Methods: Skeletal test, indirect micro-haemagglutination test population diphtheria immune level survey. Results: The positive rate of Sick's test in the population was 14.15%. The children under 6 years of age were below 10%. The age group of over 10 years old was over 10% and the 20 to 40 years old group was over 20%. Diphtheria crowd positive rate of 54.28%. Inoculation group and non-inoculation group, the entire vaccination group and the whole course of vaccination group were significantly different. CONCLUSIONS: In the absence of diphtheria cases at present, the population's immunity to diphtheria mainly comes from artificial immunity. In the current immunization program, immunization must be carried out in order to ensure the immunization effect. At the same time, we should pay attention to the vaccination work for adults and raise the immunization level of the entire population.
