摘要: 目的了解近年来乙肝疫苗普遍接种后,郑州市某民办学校学生的 HBsAg 阳性率和抗-HBs 水平状况。方法对2003～2004年郑州市民办某小哈佛双语学校465名5～15岁入学新生进行了血清免疫检测(HBsAg 和抗-HBs)。结果 HBsAg 阳性率为0．4%(2/465),较1992 年有大幅度下降,2003～2004年0～6岁年龄组未检出；抗-HBs 阳性率为58．5%(272/465),较 1992年河南省调查的抗-HBs 阳性水平有大幅度提高。结论抗-HBs 阳性率随年龄增大而降低,而 HBsAg 阳性率则随年龄增大而升高,提示加强接种疫苗的重要性。Abstract: Objective This study aimed To understand the positive rate of HBsAg and anti-HBs level among students of a voluntary school in Zhengzhou City in recent years after widespread inoculation of hepatitis B vaccine(HBV)．Methods A seroimmunity test(HBsAg and anti—HBs) was conducted for 465 students aged 5 to 15 years，who were newly enrolled in a Voluntary Little Harvard Bilingual School in Zhengzhou City from 2003 to 2004．Results The positive rate of HBsAg was O.4％(2/465)，which was greatly lower than that of 1992，and no positive case was found in the group aged 0 tO 6 years from 2003 to 2004．The positive rate of anti—HBs was 58.5％(272/465)．Which was significantly higher than that obmined from the investigation in Henan Province in 1992．Conclusion The positive rate of anti-HBs decreased with increase of age，while that of HBsAg increased with age，which showed the importance of strengthening vaccination
