摘　　要：目的 比较不同重组乙型肝炎（乙肝）疫苗加强免疫效果.方法 选择1周岁内完成血源乙肝疫苗基础免疫的10岁以上儿童2789例,分别接种4种国内常用的不同重组乙肝疫苗,分为A、B、C、D4组,采集血清,使用化学发光法检测HBsAg、抗-HBs、抗-HBc,仅抗-HBs阳性者接种1剂次、抗-HBs阴性者接种3剂次相应疫苗,免疫1个月后采血检测抗-HBs.结果 加强免疫前、免疫1剂次及3剂次后A、B、C、D 4组抗-HBs阳性率分别为36.43%、37.59%、42.91%、46.46%;89.20%、91.52%、90.96%、85.45%;99.12%、99.47%、98.87%、98.85%;加强免疫前、免疫1剂次及3剂次后两两之间抗-HBs阳性率差异均有统计学意义（P值均＜0.05）.抗-HBs阴性者加强免疫1剂次、3剂次后,抗-HBs阳转率分别为83.01%、86.41%、84.16%、72.82%;98.62%、99.16%、98.03%、97.84%;与抗-HBs阳性者加强免疫1剂次相比,4组抗-HBs阳转率差异均有统计学意义（P＜0.05）.抗-HBs阳性者加强免疫1剂次后几何平均滴度（GMT）分别为2853.21、6254.23、3581.40、3021.32 mIU/ml.抗-HBs阴性者加强免疫1剂次、3剂次后4组GMT分别为273.08、648.52、387.87、245.36 mIU/ml;632.30、2341.14、563.97、394.08 mIU/ml.结论 采用上述4种重组乙肝疫苗对抗-HBs阳性的10岁以上儿童加强免疫1剂次、对抗-HBs阴性的10岁以上儿童加强免疫3剂次,免疫效果良好.Abstract：Objective To study the efficiency of booster immunization with different recombinant hepatitis B vaccines.Methods 2789 children aged over 10 years who had completed the basic immunization of hepatitis B vaccine under 1 year old were selected.All the sampled children were classified into four groups （A,B,C and D） and immunized with different hepatitis B vaccines produced by different campanies respectively.Before booster immunization,their blood plasma specimens were detected for hepatitis B virus （HBV） surface antigen （HBsAg）,antibodies to HBV surface antigen （anti-HBs） and antibodies to HBV core antigen （anti-HBc） by chemiluminescence.In each group,the anti-HBs positive children were immunized with one dosage and anti-HBs negative children were immunized three dosages of the same vaccine.Their blood specimens were collected again after 1 month,and detected for anti-HBs.Results The anti-HBs positive rates of A,B,C and D group were 36.43%,37.59%,42.91% and 46.46% respectively before immunization while 89.20%,91.52%,90.96% and 85.45% respectively after immunization with one dosage,99.12%,99.47%,98.87% and 98.85% respectively after immunization with three dosages.The differences of anti-HBs positive rates in the four respective groups showed statistical significances between any two rates of pre-immunization,post-immunization with one dosage and post- immunization with three dosages （all P〈0.05）.The anti-HBs positive conversion rates of four groups were 83.01%,86.41%,84.16% and 72.82% respectively after immunization with one dosage.The anti-HBs positive conversion rate of four groups were 98.62%,99.16%,98.03% and 97.84% respectively after immunization with three dosages and the difference of positive conversion rates in each group showed statistical significances between booster immunization with one dosage and booster immunization with three dosages.The average GMTs in anti-HBs positive children in the four groups were 2853.21,6254.23,3581.40 and 3021.32 mIU/ml respectively afte
