摘要
对乙肝疫苗用于母婴垂直传播阻断效果进行了调查,抗体阳性率在出生后第9个月才达到60%～70%,而 HBsAg 阳性率高达29%,提示:①疫苗的抗体应答率太低;②注射乙肝疫苗后阻断母婴传播作用不理想,即保护率太低。说明应在疫苗的使用、管理、免疫方案等方面多做工作才能提高疫苗的使用效果。
We investigated into HBV vaccine effect on prevention of Mother-to-babies transmission.The positive rates of anti-HBs were 60%～70% when babies were 9 monthes,but the positive rates of HBsAg were 29%,all showed:Ⅰ,rates of antibody response to HBV vaccine were lower,z,prevention rates of HBV vaccine were lower.We discussed appliance,administration,immune plan.
