Cohort 2: Geometric Mean Titer (GMT) and Geometric Mean Ratio (GMR) of Strain-Specific Hemagglutination Inhibition Assay (HAI) Titers at 4 Weeks After Vaccination: Non-inferiority
At 4 Weeks after Vaccination

GMTs and the corresponding 2-sided confidence interval (CIs) were calculated by exponentiating the mean logarithm of the titers and the corresponding CIs (based on the Student t distribution). Assay results below the lower limit of quantitation (LLOQ) were set to 0.5 \*LLOQ. GMTs were reported in the descriptive data section of this outcome measure. GMRs were reported in the statistical analysis section. Data was reported for the following strains: H1N1, H3N2 and Victoria.

Cohort 2: Percentage of Participants and Difference in Percentage of Participants With Strain-Specific HAI Seroconversion at 4 Weeks After Vaccination: Non-inferiority
At 4 Weeks after Vaccination

Seroconversion was defined as having an HAI titer \<1:10 prior to vaccination and greater than or equal to (\>=) 1:40 at the postvaccination time point of interest, or an HAI titer of \>=1:10 prior to vaccination with a minimum 4-fold rise at the postvaccination time point of interest. Percentage of participants with seroconversion were reported in the descriptive data section of this outcome measure. Difference in percentage of participants with seroconversion were reported in the statistical analysis section. Data was reported for the following strains: H1N1, H3N2 and Victoria.

Cohort 2: GMT and GMR of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) Neutralizing Titers at 4 Weeks After Vaccination: Non-inferiority
At 4 Weeks after Vaccination

GMTs and the corresponding 2-sided CIs were calculated by exponentiating the mean logarithm of the titers and the corresponding CIs (based on the Student t distribution). Assay results below the LLOQ were set to 0.5 \*LLOQ. GMTs were reported in the descriptive data section of this outcome measure. GMRs were reported in the statistical analysis section.

Cohort 2: Percentage of Participants and Difference in Percentage of Participants With SARS-CoV-2 Seroresponse at 4 Weeks After Vaccination: Non-inferiority
At 4 Weeks after Vaccination

Seroresponse was defined as achieving a postvaccination \>=4-fold rise from baseline (before the study vaccination). If the baseline measurement was below the LLOQ, the postvaccination measure of \>=4\*LLOQ was considered seroresponse. Percentage of participants with seroresponse were reported in the descriptive data section of this outcome measure. Difference in percentage of participants with seroresponse were reported in the statistical analysis section.
