【摘要 】 目的 了解乙型肝炎疫苗的免疫后效果。方法 于1997年9~12月在北京、武汉、哈尔滨、上海、成都、兰州和长春7个城市,采用整群随机抽样方法抽取3~4岁年龄组儿童2180人进行调查。结果 1993~1994年新生儿乙型肝炎疫苗全程接种率城区为91.10%,明显高于郊区的84.71%。HBsAg阳性率降至1.56%,抗-HBs阳性率平均为70.50%。城区儿童HBsAg阳性率0.28%,郊区儿童HBsAg阳性率为2.17%,说明免疫儿童中HBsAg阳性者的主要来源在郊区。结论 上述表明,我国乙型肝炎疫苗免疫效果显著,但在郊区,疫苗免疫效果还不够理想。

The carrier rate of HBsAg decreased from 10% to 1.56% and anti-HBspositive rate was 70.50%. The carrier rate of HBsAg was 0.28% in the cities, compared with2.17% among the children in suburbs.
