Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the immunogenicity of the study vaccine in healthy adults aged 18 to 60 years according to the criteria outlined in the CPMP Note for Guidance on Harmonisation of Requirements for Influenza Vaccines (CPMP/BWP/214/96). ;Secondary Objective: To evaluate the safety of the study vaccine in adults aged 18 to 60 years. ;Primary end point(s): The percentage of evaluable participants achieving seroconversion or significant increase in antibody titre. The geometric mean fold increase (GMFI) in antibody titre after vaccination. The percentage of evaluable participants achieving a HI titre = 40 or single radial haemolysis (SRH) area = 25 mm2. ;Timepoint(s) of evaluation of this end point: Approximately 21 days after vaccination

Secondary

MeasureTime frame
Secondary end point(s): Frequency of any solicited adverse events (AEs) Frequency of any unsolicited AEs ;Timepoint(s) of evaluation of this end point: Solicited - During the 4 days after vaccination (Day 0 plus 3 days) Unsolicited - After vaccination until the end of the study; approximately 21 days.
