Clinical Trial 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.

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.

• Subjects with immune deficiency disorder.

• History of Guillain-Barre syndrome.

• Thrombocytopenia or bleeding disorder contraindicating intramuscular vaccination.

• Subjects who experienced fever within 72 hours before vaccination or with the febrile disease(exceeding 38.0?) on screening day or with any acute respiratory infection.

• Subjects who had done blood donation within a week prior to study vaccination or planned blood donation within 7 months after study vaccination.

• Subjects with clinically significant chronic disease or malignant cancer.

• Pregnant women, breast-feeding women.

• Any other condition which, in the opinion of the Investigator, prevents the subject from participating in the study.
