目的评价华宁县人群乙肝疫苗的接种效果。方法用分层整群抽样(PPS)法,在全县范围内随机抽取3个乡镇和9个行政村,按不同年龄段进行调查,并进行HBsAg和抗-HBs检测。结果在调查的382人中,完成乙肝疫苗3针次的接种率为70.7%,Anti-HBs阳性率为72.0%,HBsAg携带率为1.1%。不同年龄组乙肝疫苗接种率与抗-HBs阳性率均有统计学意义。结论华宁县人群HBsAg携带率控制在较低水平,要进一步提高新生儿乙肝疫苗及时接种率,确保3针次疫苗按时接种,提高免疫人群的接种质量。
Objective To evaluate the vaccination effect of hepatitis B vaccine in Huaning County. Methods By stratified cluster sampling (PPS) method, three townships and nine administrative villages were randomly selected in the whole county. According to different age groups, HBsAg and anti-HBs were detected. Results Among the 382 surveyed persons, the vaccination rate of completing 3 doses of hepatitis B vaccine was 70.7%, the positive rate of Anti-HBs was 72.0% and the carrier rate of HBsAg was 1.1%. Hepatitis B vaccination rates and anti-HBs positive rates in different age groups were statistically significant. Conclusion The population carrying rate of HBsAg in Huaning County is controlled at a relatively low level. The timely vaccination rate of newborn hepatitis B vaccine should be further improved to ensure timely vaccination of the 3-dose vaccines and to improve the vaccination quality of immunized groups.
