中国西部12个省(自治区、直辖市)乙型肝炎疫苗接种情况分析

目的对中国西部12个省(自治区、直辖市,下同)常规免疫报告接种率数据进行分析,指导乙型肝炎(乙肝)疫苗(HepB)接种工作的评价。方法利用同期HepB实种人数和百白破联合疫苗(DTP)应种人数相比,估算HepB接种情况。结果尽管各省报告HepB全程接种率很高,2001~2004年平均分别为86.95%、91.02%、92.49%、96.67%,但估算接种率较低,2001~2004年分别为48.2%、52.53%、61.96%、80.83%,2004年HepB首针及时接种率估算仅为58.38%。结论各省报告HepB接种率和估算接种率差距表明,HepB接种率未达到卫生部/全球疫苗免疫联盟项目既定的HepB3接种率85%和HepB1及时接种率75%的目标,必须加强HepB纳入免疫规划工作。

Analysis on Hepatitis B Immunization Coverage in 12 Western Provinces in China

Objective In order to provide a better improved method to evaluate the reported data of hepatitis B immunization,we have conducted an assessment of the routine immunization database from 12 Western Provinces. Method Comparing the DTP targeted and HBV administrated in the same cohort and period,and observing the differences between reported and estimated immunization coverage. Results The reported coverage with three dose HepB from 12 Western Provinces were relative high,with the average coverage of 86.95%,91.02%,92.49%,and 96.67%,from 2001 to 2004 respectively.The estimated coverage were much low,with the average coverage of 48.2%,52.53%,61.96%,80.83%.The same period,the coverage of estimated birth dose of HBV in 2004 was only 58.38%.Conclusion The gaps of reported and estimated coverage showed that there are challenges for the GAVI project,and that most of the provinces did not meet the mational goals of 85% for three doses of coverage,and 75% for birth dose coverage.It is also suggested that the hepatitis B immunization in Western Provinces should be enhanced.
