Study Summary

This is a study to assess the immune (antibody) response and safety of a Seqirus split virion, inactivated Quadrivalent Influenza Vaccine (Seqirus QIV), in comparison with a US licensed 2016/2017 Quadrivalent Influenza Vaccine (comparator QIV) in a healthy pediatric population 6 months through 59 months of age.

Primary Outcome

Noninferiority of Seqirus QIV compared to comparator QIV was assessed by hemagglutination inhibition (HI) antibody geometric mean titer (GMT) for each viral strain included in the vaccines. The GMT ratio is defined as the geometric mean of the postvaccination HI titer for the US-licensed comparator QIV over the geometric mean of the postvaccination HI titer for Seqirus QIV. B/VIC = B/Victoria B/YAM = B/Yamagata
