Name Time Method Main Objective: To evaluate the immunogenicity of the 2012/2013 formulation of the Enzira® vaccine in ‘Adults’ (aged 18 to 59 years) and in ‘Older Adults’ (aged 60 years or older) according to the criteria outlined in the CPMP Criteria. <br><br><br>;Secondary Objective: To evaluate the safety of the 2012/2013 formulation of the Enzira® vaccine in ‘Adults’ (aged 18 to 59 years) and in ‘Older Adults’ (aged 60 years or older). <br><br>;Primary end point(s): The percentage of evaluable participants achieving seroconversion or significant increase in antibody titre.<br><br>The geometric mean fold increase (GMFI) in antibody titre after vaccination.<br><br>The percentage of evaluable participants achieving a HI titre = 40 or single radial haemolysis (SRH) area = 25 mm2.<br>;Timepoint(s) of evaluation of this end point: Approximately 21 days after vaccination<br>
- Secondary Outcome Measures
Name Time Method Timepoint(s) of evaluation of this end point: During the 4 days after vaccination (Day 0 plus 3 days) for solicited adverse events(AEs).<br>After vaccination until the end of the study; approximately 21 days for any unsolicited adverse events(AEs).<br>;Secondary end point(s): Frequency and intensity of any solicited adverse events (AEs)<br><br>Frequency of any unsolicited AEs<br>
