Phase Ⅲ, Clinical Trial to Compare an Inactivated Quadrivalent Influenza Vaccine and a Licensed Vaccine in Chile

Summary

This study compares the immunogenity and safety of quadrivalent inactivated influenza vaccines. The experimental group receives the quadrivalent influenza vaccine developed by Sinovac Biotech Co., Ltd and the control group immunized with Vaxigrip Tetra™. The group has 1600 persons from general population 3 years and older. The design is double-blind and randomized. The primary outcome is the immunogenicity against the 4 strains of influenza included in both vaccines.
