4. juli 2018 opdateret af: GlaxoSmithKline

A Study to Evaluate the Safety and Immunogenicity of an A/California/7/2009 (H1N1)V-like Vaccine GSK2340274A or GSK2340273A Co-administered With Trivalent Inactivated Seasonal Influenza Vaccine in Adults 19 to 40 Years of Age

The purpose of this study is to characterize the safety and immunogenicity of the H1N1 (swine) flu vaccines GSK2340274A and GSK2340273A when co-administered with the seasonal flu vaccine in adults 19 to 40 years of age.
