The present study is designed to confirm the safety and immunogenicity of cell-derived, trivalent, surface antigen, inactivated influenza vaccine in 2 age cohorts: 18 to ≤60 years and ≥61 years and the antibody response to each influenza vaccine antigen, as measured by Single Radial Hemolysis (SRH) or Hemagglutination Inhibition (HI) at approximately 21 days post immunization. The vaccine composition will be based on the WHO-recommended influenza strains for the 2013/2014 Northern Hemisphere vaccine. The results of this study are intended to support the use of this vaccine in future influenza seasons if the recommended vaccine composition remains the same, in compliance with the requirements of the current EU recommendations for clinical trials related to yearly licensing of influenza vaccines.
