Name Time Method 1.Seroprotection rate-After vaccination, calculate the proportion of subjects whose HI titer increased to 1:40 or higher. 2. Seroconversion rate-Calculate the proportion of subjects who satisfy one of the following. -If HI titer <1:10 before vaccination, subjects with HI titer = 1:40 after vaccination 3. Geometric Mean Ratio-Calculate the geometric mean increase rate of HI titer before and after vaccination
