|---|---|---|---|---|---|
| Group 1 | Q/LAIV (MEDI3250) | Q/LAIV (quadrivalent influenza vaccine) (MEDI3250) was supplied in the Becton Dickinson (BD) Accuspray device that delivers a 0.2 mL total volume intranasal dose divided into each nostril (ie, administered as 0.1 mL per nostril). Each 0.2 mL dose contained 10\^7.0 ± 0.5 fluorescent focus units (FFU) of each of 4 temperature sensitive, cold-adapted, attenuated, 6:2 reassortant influenza strains (A/H1N1 \[A/South Dakota/6/2007\], A/H3N2 \[A/Uruguay/716/2007\], B/Victoria \[B/Malaysia/2506/2004\], and B/Yamagata \[B/Florida/4/2006\]). | 714 | 930 | OG000 |
| Group 2 | FluMist/B/Victoria | FluMist/B/Victoria(trivalent influenza vaccine) was supplied in the BD Accuspray device that delivers a 0.2 mL total volume intranasal dose divided into each nostril (ie, administered as 0.1 mL per nostril). Each 0.2 mL dose contained 10\^7.0 ± 0.5 FFU of each of 3 temperature sensitive, cold-adapted, attenuated, 6:2 reassortant influenza strains (A/H1N1 \[A/South Dakota/6/2007\], A/H3N2 \[A/Uruguay/716/2007\], and B/Victoria \[B/Malaysia/2506/2004\]). | 175 | 231 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- The Number of Seropositive Participants Within Each Treatment Arm Who Achieved a B/Victoria Strain-specific HAI Antibody Titer ≥ 32 Post Dose.
- Description
- Participants with a baseline HAI titer \> 8 were considered to be seropositive for that strain.
- Time frame
- Day 28-35
- Population
Participants who received a full dose of investigational product (Q=1198; FV=301), had post-dose HAI measurement (Q=1182; FV=298), had no protocol deviation that could have interfered with the generation or interpretation of an immune response (Q=1181; FV=297), and were seropositive to the strain (Q=930; FV=231).
