[目的]了解人群甲型H1N1流感(甲流)病毒抗体水平,掌握接种甲流疫苗后的免疫效果。[方法]2010年1～3月,在龙岩市新罗区白砂镇随机抽取0～5、6～17、18～55、56～71岁健康人群合计140人,进行甲流血清抗体检测,对其中抗体阴性者进行甲流疫苗接种前后抗体水平比较。[结果]调查140人,甲流血清抗体阳性率为6.43%。抗体阳性率,男性为2.86%,女性为10.00%(P>0.05);0～5岁为6.67%,6～17岁为14.29%,18～55岁为2.00%,56～71岁为0.00%(P>0.05)。84名抗体阴性者接种疫苗后21d,抗体阳性率为66.67%,明显高于接种前(P<0.01)。[结论]人群甲型H1N1流感抗体阳性率较低,接种甲型H1N1流感疫苗能够产生较好的免疫应答。
[Objective] To understand the antibody level of Influenza A (H1N1) virus in a population and to know the immune effect after vaccination with A flu vaccine. [Methods] From January to March 2010, a total of 140 healthy people aged 0-5, 6-17, 18-55 and 56-71 years old were randomly selected from Baisha Town, Xinluo District, Longyan City for serum antibody detection of A Antibody-negative patients were compared before and after antibody vaccination. [Results] Investigation of 140 people, a positive serum antibody was 6.43%. The antibody positive rate was 2.86% in males and 10.00% in females (P> 0.05). The average prevalence was 6.67% at 0-5 years, 14.29% at 6-17 years, 2.00% at 18-55 years, 0.00% at 56-71 years, (P> 0.05). The antibody positive rate was 66.67% at 21 days after vaccination, which was significantly higher than that before vaccination (P <0.01). [Conclusion] The positive rate of influenza A (H1N1) antibody in the population is low. Influenza A (H1N1) vaccination can produce a better immune response.
