结局指标
主要结局
CSL's IVV Overall Vaccine Efficacy (VE) Versus Placebo Through Assessment of Incidence of Laboratory Confirmed Influenza A/B Infection
时间窗: 2008 and 2009 Southern Hemisphere influenza seasons, until 30 November 2009
Incidence of Laboratory Confirmed Influenza A/B infection was assessed per the study population in the 2008 and 2009 Southern Hemisphere influenza seasons. Vaccine efficacy = 100 x (1 - ratio of incidence rate). Ratio of incidence rate = active Study Vaccine recipient infection rate / placebo recipient infection rate.
