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。
Objective To estimate the coverage of routine immunization coverage in the whole country (excluding Hong Kong, Macao Special Administrative Region and Taiwan, the same below) and analyze the influencing factors of inoculation rate. Methods Through the China immunization program monitoring information management system, we collected the data of routine immunization coverage from 2005 to 2007 in our country and estimated the vaccination rate using the estimation model recommended by the World Health Organization (WHO). Results The reported rates of routine immunization in China from 2005 to 2007 were 79.8%, 92.3% and 92.0%, respectively. The reported numbers of routine immunization vaccines ranged from 12.3 million to 14.06 million and the actual number of vaccinated animals ranged from 9.13 million to 13.95 million. Inoculation rate reported 89% to 100%, estimated vaccination rate of 78% to 94%. Conclusion In general, the routine immunization report integrity, reported vaccination coverage and estimated vaccination coverage are all on the rise. However, there is still a large gap between the estimated vaccination coverage and reported coverage. When using the WHO recommendation to estimate the vaccination rate model, carefully select the birth population and the correction factor.
