Study Endpoints

Primary Endpoints

Summary of the Pre- and Post-Vaccination Geometric Mean Titers (GMTs) for Each of the Influenza Vaccine Antigens.
Days 0 and 21 post-vaccination
Percentage of Participants With Seroprotection to Each of the Influenza Vaccine Antigen Before and Post-vaccination.
Day 21 post-vaccination

Seroprotection was defined as a titer ≥ 40 1/dil, and determined in participants with a valid serology result for the particular Flu strain, including results reported as less than lower limit of quantitation (LLOQ)

Percentage of Participants Achieving Seroconversion or Significant Increase at Day 21 Following Vaccination With Influenza Vaccine.
Day 21 post-vaccination

Seroconversion: For participants with a Day 0 pre-vaccination titer \< 10 (1/dil), titer ≥ 40 (1/dil) on Day 21. Significant Increase: For participants with a Day 0 pre-vaccination titer ≥ 10 (1/dil), ≥ 4-fold increase of titer on Day 21.

Secondary Endpoints

Number of Participants Reporting at Least 1 Solicited Injection Site or Systemic Reaction Post-vaccination With Influenza Vaccine.
