NCT03275389

Brief Summary

The purpose of this study is to assess the reactogenicity, safety and immunogenicity of different formulations of GlaxoSmithKline (GSK) Biologicals' investigational supra-seasonal universal influenza vaccines (SUIVs) (unadjuvanted or adjuvanted) in 18 to 39 year-old healthy subjects. Subjects will be enrolled and vaccinated with one or 2 primary dose(s) followed by a booster dose one year later.

Masking Details
The site staff will work in an observer-blind manner. As the vaccines appearance and preparation are different, two teams of study personnel will be set up: * A team of unblinded personnel (responsible for the reception, preparation and administration of the vaccines). * A team of blinded personnel (responsible for the clinical safety evaluation of the subjects).
