青海省2009年1～6岁健康儿童接种乙肝疫苗免疫抗体水平调查分析

目的调查青海省1～6岁健康儿童接种乙肝疫苗抗体水平,抽样评价预防接种质量。方法在全省六州一地区一市各选择1个县对1～6岁健康儿童进行接种乙肝疫苗抗体检测。结果乙肝疫苗(抗-HBs≥10mIU/mL)1]阳性率为63.62%,其中最高为海东地区76.67%,最低为果洛州48.57%。不同地区的抗-HBs阳性率高低分布不均,乙肝疫苗抗体阳性率仍有差别,其中果洛州监测人群抗-HBs阳性率相对较低仅为48.57%。不同性别、民族及年龄抗-HBs阳性率为抗体阳性率差异无统计学意义。结论我省乙肝疫苗接种与免疫成功率≥85%的指标还有较大差距,应进一步提高乙肝疫苗疫苗接种率。
