Safety and Immunogenicity of Different Formulations of an Adjuvanted, Trivalent Subunit Influenza Vaccine in Elderly Subjects 65 Years of Age and Above

NCT02126761 | PHASE 1 | INTERVENTIONAL

In this study, the safety and immunogenicity of the current formulation of aTIV will be compared to aTIV-modified formulations in which the dosage of the MF59 adjuvant will be doubled or tripled and/or the dosage of the 3 influenza virus strains will be doubled, in independently-living elderly subjects ≥ 65 years of age.
