Immunogenicity and Safety of AdimFlu-S 2011-2012 in Non-Elderly Adult and Elderly Subjects

July 10, 2012 updated by: Adimmune Corporation

Immunogenicity and Safety of a Trivalent Inactivated Influenza Vaccine, Formulation 2011-2012, in Non-Elderly Adult and Elderly Subjects

The purpose of this study is to evaluate the antibody response to each of the three influenza vaccine strains included in the licensed seasonal flu vaccine, as measured by hemagglutination inhibition (HAI) at 21 days post immunization in non-elderly and elderly subjects in compliance with the requirements of the current European Union (EU) recommendations for the evaluation of the immunogenicity for a new formulation of a licensed flu vaccine (CPMP/BWP/214/96).
