Study of Egg-derived Influenza Vaccine and Cell Culture-derived Influenza Vaccine in Healthy Children and Adolescents

Phase 3
Completed
Conditions
Influenza, Human
Interventions
Biological: NBP607
Biological: Agrippal S1
Registration Number
NCT02621177
Lead Sponsor
SK Chemicals Co., Ltd.
Brief Summary

This study is a multi-center, randomized, double-blind Phase III clinical trial. The aim of the study is to describe the immunogenicity and safety of the trivalent cell culture-derived influenza vaccine compared to the trivalent egg-derived influenza vaccine among subjects.

Detailed Description

Subjects are randomly assigned in a 4:1 ratio to NBP607-QIV versus Agrippal S1. To assess the immunogenicity, antibody levels are evaluated by hemagglutination inhibition(HI) assay from sera obtained at pre-vaccination and 28 days post-vaccination. To assess the safety, solicited adverse events for 7 days post-vaccination and unsolicited adverse events for 28 days post-vaccination are assessed and reported. The serious adverse events are collected during 6 months post-vaccination.
