Primäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Summary of the Pre- and Post-Vaccination Geometric Mean Titers (GMTs) for Each of the Influenza Vaccine Antigens.
Zeitfenster: Days 0 and 21 post-vaccination
|
Days 0 and 21 post-vaccination
|
|
|
Percentage of Participants With Seroprotection to Each of the Influenza Vaccine Antigen Before and Post-vaccination.
Zeitfenster: 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)
|
Day 21 post-vaccination
|
|
Percentage of Participants Achieving Seroconversion or Significant Increase at Day 21 Following Vaccination With Influenza Vaccine.
Zeitfenster: 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. |
Day 21 post-vaccination
