PRIMARY outcome

Timeframe: Day 22

Population: The full analysis set was used.

Seroprotection rate is measured by HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination. Seroprotection Rate was defined as the percentage of participants with HI antibody titer ≥ 40 for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain).

Timeframe: Day 22

Seroconversion rate is measured by HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination. Seroconversion Rate was defined as the perccentage of participants with a baseline HI antibody titer of ≥ 10 achieving a minimal 4-fold increase, or baseline HI antibody titer of \< 10 achieving an HI antibody titer of ≥ 40 for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain).

For continuous variables, summary statistics of measured values and respective changes from baseline will be calculated at each evaluation time point. In addition, figures illustrating individual changes will be created. For discrete variables, shift tables (before and after vaccination) will be created.

Timeframe: Day 1 and Day 22

The ECG data will be analyzed into 3 categories, 'normal', 'abnormal but not clinically significant' and 'abnormal clinically significant'. Using these variables, shift tables (before and after vaccination) will be created by individual participant. . The definitions for the acronyms are as follows: Within Normal Limits (WNL), Not Clinically Significant (NCS), and Clinically Significant (CS).
