乙肝疫苗或高效价乙肝免疫球蛋白(HBIG)单独应用预防乙型肝炎传播的免疫效果均不如两者联合应用。联合应用的针次、间隔时间仍在探讨中。本文研究的目的是采用二种不同免疫方案,观察阻断母婴传播效果及幼儿单独应用乙肝疫苗的免疫效果。
Hepatitis B vaccine or high titer hepatitis B immunoglobulin (HBIG) used alone to prevent the spread of hepatitis B immune effect are not as good as the combination of both. Joint application of the needle, the interval is still under discussion. The purpose of this study is to use two different immunization programs to observe the effect of blocking the mother-to-child transmission and the immune effect of the hepatitis B vaccine alone.
