NCT01411358

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • The primary endpoint will be the seroprotection rate which is defined as the proportion of subjects with HAI titer ≥ 40.

    Serum samples will be tested for anti-hemagglutinin (HA) antibodies by hemagglutination inhibition (HAI).

    3 weeks post vaccination
