ListOutcomeTime frameDescription
Primary
The Post Dose Strain-specific Serum Hemagglutination Inhibition (HAI) Antibody Geometric Mean Titers (GMTs) in the Q/LAIV-BFS (MEDI8662) Arm as Compared to Those in the Combined Flumist Arms (All Flumist Group).
Day 28 to 35
Noninferior immune response was assessed by evaluating the upper bound of the 2-sided 95% confidence intervals (CIs) for the ratios of strain-specific HAI GMTs for the specified comparisons. The GMT ratio = GMT in comparator (All FluMist group) divided by the GMT in the Q/LAIV-BFS arm.
SecondaryThe Percentage of Participants Experiencing Post Dose Strain-specific HAI Antibody Seroresponse to the A/H1N1 and A/H3N2 Strains in All Participants, Regardless of Baseline Serostatus.Day 0 and Day 28-35
Seroresponse was defined as a ≥ 4-fold rise in HAI titer from baseline. The comparators for seroresponse to the A/H1N1 and A/H3N2 strains were participants in the All FluMist group (combined data for both FluMist arms).
SecondaryThe Percentage of Participants Experiencing Post Dose Strain-specific HAI Antibody Seroresponse to the B/Yamagata Strain in All Participants, Regardless of Baseline Serostatus.Day 0 and Day 28-35Seroresponse was defined as a ≥ 4-fold rise in HAI titer from baseline. The comparator for seroresponse to the B/Yamagata strain was participants in the FluMist/B/Yamagata arm.
SecondaryThe Percentage of Participants Experiencing Post Dose Strain-specific HAI Antibody Seroresponse to the B/Victoria Strain in All Participants, Regardless of Baseline Serostatus.Day 0 and Day 28-35Seroresponse was defined as a ≥ 4-fold rise in HAI titer from baseline. The comparator for seroresponse to the B/Victoria strain was participants in the FluMist/B/Victoria arm.
SecondaryThe Percentage of Serosusceptible Participants Experiencing Post Dose Strain-specific HAI Antibody Seroresponse to the A/H1N1 Strain.Day 0 and Day 28-35
Seroresponse was defined as a ≥ 4-fold rise in HAI titer from baseline. Participants with a baseline HAI titer ≤ 8 were considered to be serosusceptible for that strain. The comparator for seroresponse to the A/H1N1 strain was participants in the All FluMist group (combined data for both FluMist arms).
