目的了解人群甲型H1N1流感病毒裂解疫苗(下称甲型H1N1流感疫苗)接种情况及其免疫效果,为甲型H1N1流感防控及疫苗的科学使用提供依据。方法回顾性分析2009年10月～2011年7月我市进行甲型H1N1流感疫苗接种人群的分布特征,并与同期未接种人群比较甲型H1N1流感发生情况。结果我市总人口接种率为6.26%,其中学生接种率最高为73.44%。我市近3年来所有接种人群均未发病,接种人群甲型H1N1流感发生率明显低于未接种人群(χ2=4.134,P<0.05)。结论实施对易感人群进行甲型H1N1流感疫苗接种对控制甲型H1N1流感有较好的效果。
Objective To understand the population vaccination status of Influenza A (H1N1) virus and its immunization effect and to provide basis for the prevention and control of Influenza A (H1N1) and the scientific use of the vaccine. Methods The distribution characteristics of influenza A (H1N1) vaccines in our city from October 2009 to July 2011 were retrospectively analyzed. The incidence of influenza A (H1N1) was compared with that of unvaccinated persons in the same period. Results The total population vaccination rate in our city was 6.26%, of which the highest rate of student vaccination was 73.44%. The incidence of influenza A (H1N1) in vaccinated population was significantly lower than that in non-vaccinated population (χ2 = 4.134, P <0.05). Conclusions The implementation of influenza A (H1N1) vaccination in susceptible population has good effect on controlling the influenza A (H1N1).
