2005～2007年中国常规免疫报告接种率的估算

目的估算全国（未包括香港、澳门特别行政区和台湾地区,下同）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,收集全国2005～2007年常规免疫接种率报告数据,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2005～2007年全国常规免疫接种报告完整率分别为79.8%、92.3%、92.0%;常规免疫各疫苗报告应种人数在1230万～1406万,实种人数913万～1395万;各疫苗各剂次报告接种率为89%～100%,估算接种率为78%～94%。结论总体上,常规免疫报告完整性、报告接种率和估算接种率均不断上升,但估算接种率与报告接种率仍存在较大差距。在使用WHO推荐估算接种率模型时,需慎重选择出生人口和校正系数。

Study on the Estimation of Routine Immunization Coverage of China,2005-2007

Objective This study is to estimate the routine immunization coverage of China,and to analyse the effect factors. Methods The reported routine coverage data in 2005-2007 were collected through China Immunization information system. The estimated coverage method used in this study,which was recommended by the World Health Organization （WHO）. Results The percentage of county reported routine immunization were 79.8%,92.3% and 92.0% respectively in 2005～2007; the targeted population of routine immunization reported from China immunization information system were 123～140.6 million,the vaccinated population were between 91.3～139.5 million; reported routine immunization coverage of each vaccine dose varied from 89%～100%,and estimated coverage varied from 78%～94%. Conclusion The reported and estimated routine immunization coverage increased year by year. However,there is still a large gap between the reported data and the estimated data. It is recognized that the birth cohort and the adjusted .index from the WHO recommended method should be used carefully.
