Excess deaths and immunoprotection during 1918-1920 influenza pandemic, Taiwan.
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.
