目的估算江苏省常规免疫报告接种率,分析估算接种率的影响因素。方法通过中国免疫规划监测信息管理系统,收集江苏省2007～2009年常规免疫报告接种率数据,利用世界卫生组织(WHO)推荐的估算模型进行接种率估算。结果江苏省2007～2009年常规免疫报告完整率均为100%;常规免疫各疫苗报告应种人数在82.65万～92.21万,实种人数79.91万～91.14万;各疫苗各剂次报告接种率为98.18%～99.90%,估算接种率为85.49%～99.87%。结论江苏省常规免疫报告接种率和估算接种率总体上均处于较高水平,但局部地区估算接种率与报告接种率存在一定差距。在使用WHO推荐估算接种率模型时,需慎重选择出生人口,建议东部地区校正系数可取值0.7～0.8。
Objective To estimate the vaccination coverage of routine immunization in Jiangsu Province and analyze the influencing factors of inoculation rate. Methods The surveillance information management system of China immunization program was used to collect the routine immunization report coverage rate data from 2007 to 2009 in Jiangsu Province. The vaccination rate was estimated by the World Health Organization (WHO) estimation model. Results The complete report rate of routine immunization in Jiangsu Province from 2007 to 2009 was 100%. The routine vaccination reports of all kinds of vaccines ranged from 826,500 to 922,100 and the actual number was 719,100 to 911,400. The inoculation rates of each vaccine were 98.18% ~ 99.90%, estimated vaccination rate was 85.49% ~ 99.87%. Conclusion The immunization coverage rate and estimated vaccination rate of routine immunization in Jiangsu Province are generally at a high level, but there is a certain gap between the estimated vaccination rate and the reported vaccination rate in some areas. When using the WHO recommendation to estimate the inoculation rate model, the population of births should be carefully selected. The correction coefficient for the eastern region is suggested to be 0.7 to 0.8.
