To determine the difference in age-specific immunoprotection during waves of influenza epidemics, we analyzed excess monthly death data for the 1918-1920 influenza pandemic in Taiwan. For persons 10-19 years of age, percentage of excess deaths was lowest in 1918 and significantly higher in 1920, perhaps indicating lack of immunoprotection from the first wave.
为了确定流感大流行期间不同年龄段免疫保护的差异,我们分析了台湾 1918-1920 年流感大流行期间的超额每月死亡数据。对于 10-19 岁的人,1918 年的超额死亡率最低,1920 年显著升高,这可能表明第一波流感没有提供足够的免疫保护。
