|---|---|---|---|---|---|
| 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 \[B/Florida/4/2006\]). | 2 | 291 | OG000 |
| Group 2 | All FluMist | All FluMist group for A/H1N1 and A/H3N2 strains, where data from both the FluMist/B/Yamagata arm and the FluMist/B/Victoria arm were combined. | 1 | 160 | OG001 |

Outcome
- Type
- SECONDARY
- Title
- The Number of Seropositive Participants Within Each Treatment Arm Who Experience A/H1N1 Strain-specific Seroresponse Post Dose.
- Description
- Seroresponse was defined as a ≥ 4-fold rise in HAI titer from baseline. Participants with a baseline HAI titer \> 8 were considered to be seropositive for that strain.
- Time frame
- Day 0 and Day 28-35
- Population
Participants who received a full dose of investigational product (Q=1198; All FM=600), had pre-dose and post-dose HAI measurement (Q=1181; All FM=590), had no protocol deviation that could have interfered with the generation or interpretation of an immune response (Q=1180; All FM=589), and were seropositive to the strain (Q=291; All FM=160).
