摘要
本文收集了１９８２～１９９３年人群ＨＢｓＡｇ携带率的监测数据，分别对乙肝疫苗使用前后的ＨＢｓＡｇ阳性率进行了分析，并试用寿命表生存率法对初免后人群ＨＢｓＡｇ感染的免疫保护率进行了评价。结果显示，接种组免疫保护率４年起下降明显，提示国产乙肝血源疫苗的加强免疫年龄以４～５岁为宜。
According to the survey data of HBsAg prevalence rate of population, the HBsAg positive rate was analyzed before and after immunization with hepatitis B vaccine prepared from plasma (HB-VAX) in 1982-1992, using life-table-method. The results showed that the protective rate dropped obviously after the 4th year of vaccination. It has been found that the children at 4～5 years old should be vaccinated again with HB-VAX.
