839例 HBsAg 阳性的孕妇所产的新生儿,被分成4组,A 组婴儿出生后给予 HBIG 注射。B 组婴儿注射 HBIG 和乙型肝炎疫苗。C 组只给予疫苗。D 组是对照。研究结果表明 HBIG 和乙肝疫苗都能阻断乙型肝炎不从 HBsAg 阳性的母亲传给婴儿。HBIG 可在注射后立刻起作用,而疫苗可作用一个长的时间。B 组获得最佳的效果。
Newborns from 839 HBsAg-positive pregnant women were divided into 4 groups. Group A infants were given HBIG injection after birth. Group B infants were injected with HBIG and hepatitis B vaccine. Group C was given only vaccine. Group D is the control. The results show that both HBIG and hepatitis B vaccines prevent hepatitis B from not passing from HBsAg-positive mothers to babies. HBIG can act immediately after injection, and the vaccine can take a long time. B group for the best results.
