To evaluate the effectiveness of influenza vacation, we conducted analyses at both individual level and health region level. The association between influenza vaccination and hospital admission was examined among 128,677 subjects 12+ years of age who participated in a national survey in 2005. Both influenza and hospital admission proportions varied across health regions. Health regions with higher proportions of influenza vaccination had significantly lower proportions of hospitalization. A 10% increase in influenza vaccination less than 1 year ago was associated with a reduction of 11% in the risk of hospitalization over a 12-month time period at the health region level.
为了评估流感假的效果,我们在个体层面和卫生区域层面进行了分析。我们对 2005 年参与全国调查的 128677 名 12 岁及以上人群进行了分析,以评估流感疫苗接种与住院之间的关联。流感和住院比例在不同卫生区域之间存在差异。流感疫苗接种比例较高的卫生区域,其住院比例显著较低。在 12 个月的时间内,在过去不到 1 年内,流感疫苗接种率每增加 10%,与该卫生区域的住院风险降低 11%相关。
