作者选择HBsAg、抗-HBs、抗-HBc阴性(RIA法)的医务人员,按性别和平均年龄均衡分两组。按0、1、6月方案,于上臂外侧肌肉注射中国地鼠卵巢(CHO)细胞重组乙型肝炎疫苗(CDV、adw亚型)10μg(131人)或血源性乙型肝炎疫苗(PDV、富含adr亚型)20μg-(112人)。于第1剂疫苗注射时及注射后1、6、7、12、18和24个月采血,分别测定抗-HBs滴度,临界值1.0以上为抗-HBs阳转。结果表明,注射疫苗后1个月,两组抗-HBs差异不显著;6个月时,CDV组的抗-HBs几何平均滴度(GMT)约比PDV组高7倍;7个
The authors selected HBsAg, anti-HBs, anti-HBc-negative (RIA) medical staff, by gender and mean age evenly divided into two groups. According to the protocol of 0, 1, and 6 months, 10 μg (131) of Chinese hamster ovary (CHO) cell recombinant hepatitis B vaccine (CDV, adw subtype) or Hepatitis B vaccine (PDV) Rich in adr subtype) 20 μg - (112). Anti-HBs titers were measured at the first dose of vaccine and at 1, 6, 7, 12, 18 and 24 months after injection. The cutoff of anti-HBs was 1.0. The results showed that there was no significant difference in anti-HBs between the two groups at 1 month after vaccination. At 6 months, the mean geometric mean anti-HBs titer (GMT) of CDV group was about 7 times higher than that of PDV group and 7
