Safety and Immunogenicity of a Subunit Trivalent Influenza Vaccine, Northern Hemisphere Formulation 2013/2014, Including MF59C.1 Adjuvant, in Healthy Adults ≥65 Years of Age

Summary

The present study is designed to confirm the safety and immunogenicity of trivalent, surface antigen, inactivated influenza vaccine including MF59C.1 adjuvant, formulation 2013/2014 Northern Hemisphere, in adults ≥65 years of age. For the immunogenicity endpoints the antibody response to each influenza vaccine antigen, will be measured by means of Single Radial Hemolysis (SRH) or Hemagglutination Inhibition (HI) at approximately 21 days post immunization. The vaccine composition will be based on the World Health Organization (WHO) recommended influenza strains for 2013/2014 Northern Hemisphere. 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 European Union (EU) recommendations for clinical trials related to yearly licensing of influenza vaccines.
