目的评价江苏省丰利镇流感疫苗的接种效果。方法选取2013年10月-2014年2月于卫生所进行流感疫苗接种的老年人137例作为观察组,选取同期未进行流感疫苗接种的老年人129例作为对照组,观察并比较2组老年人1个月、3个月和6个月的流感样疾病发病率与就诊率,并计算疫苗接种保护率。结果观察组1个月流感样疾病发病为1例(0.7%)例,3个月为3例(2.2%),6个月为9例(6.6%),就诊率1个月为0例,3个月为2例(1.5%),6个月为7例(5.1%),对照组1个月流感样疾病发病为6例(4.7%),3个月为13例(10.1%),6个月为24例(18.6%),就诊率1个月为5例(3.9%),3个月为10例(7.8%),6个月为22例(17.1%),2组患者1个月、3个月和6个月时流感样疾病发病率与就诊率比较差异均有统计学差异(P<0.05);患者1个月疫苗接种保护率为81.6%,3个月为66.2%,6个月为58.1%。结论流感疫苗接种的预防效果好,能有效降低老年人的发病率与就诊率,值得在基层工作中予以推广。
Objective To evaluate the vaccination effect of influenza vaccine in Fengli Town of Jiangsu Province. Methods A total of 137 elderly patients who received influenza vaccination at the clinic from October 2013 to February 2014 were selected as the observation group and 129 elderly persons who did not receive influenza vaccination during the same period were selected as the control group. Influenza-like morbidity and visit rates were calculated at 1 month, 3 months and 6 months, and vaccination coverage rates were calculated. Results In the observation group, the incidence of influenza-like illness was 1 case (0.7%) at 1 month, 3 cases (2.2%) at 3 months, 9 cases (6.6%) at 6 months, 2 cases (1.5%) in 3 months, 7 cases (5.1%) in 6 months, 6 cases (4.7%) in 1 month in the control group, 13 cases (10.1%) in 3 months, 24 months (18.6%) in 6 months, 5 cases (3.9%) in 1 month, 10 cases in 3 months (7.8%) and 22 cases (17.1% in 6 months) There was a significant difference in the incidence of influenza-like illness and the visiting rate at months, 3 months and 6 months (P <0.05). The 1-month vaccination protection rate was 81.6% in one month, 66.2% in 3 months, , 58.1% in 6 months. Conclusion Influenza vaccination has a good preventive effect and can effectively reduce the incidence and visiting rate of elderly people. It is worth to be promoted in grass-roots work.
