Study Summary

The purpose of this study was to show that quadrivalent live attenuated influenza vaccine (Q/LAIV-BFS; MEDI8662) was at least as immunogenic as two different forms of the commercial vaccine, FluMist, by comparing the strain-specific antibody levels in the blood.

Primary Outcome

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.
