Immunogenicity, Safety and Tolerability of a Plant-Derived Seasonal Virus-Like-Particle Quadrivalent Influenza Vaccine in Adults

Summary

A phase II trial multicenter, observer-blind, randomized, dose-ranging, placebo-controlled study to evaluate the immunogenicity, safety, and tolerability of a single intramuscular injection of plant-derived Seasonal VLP Quadrivalent Influenza Vaccine administered to healthy adults 18-49 years of age. A total of three hundred subjects will be randomized in four (4) groups of 75 subjects to receive one injection of either a low, a medium, or a high dose level of the quadrivalent VLP influenza vaccine or the placebo preparation (100 millimolar (mM) phosphate buffer + 150 mM sodium chloride (NaCl) + 0.01% Tween 80).
