| Measure | Time frame |
|---|---|
| Main Objective: To assess in elderly subjects >=60 years old, the safety and reactogenicity of re-vaccination with the low dose adjuvanted (AS03) influenza vaccine, during the entire study period (30 days). Fluarix will be used as reference.;Secondary Objective: To assess the immunogenicity (GMT, seroconversion factor, seroconversion rate and seroprotection rate) 21 days following re-vaccination with the low dose adjuvanted (AS03) influenza vaccine, given intramuscularly in elderly >=60 years old. Fluarix will be used as reference.;Primary end point(s): •Occurrence, intensity and relationship to re-vaccination of solicited local and general signs and symptoms during a 7-day follow-up period (i.e. day of re-vaccination and 6 subsequent days) after re-vaccination in each group. •Occurrence, intensity and relationship to re-vaccination of unsolicited AEs during a 30-day follow-up period (i.e. day of re-vaccination and 29 subsequent days) after re-vaccination in each group. •Occurrence and relationship to re-vaccination of serious adverse events during the entire study period in each group. | — |
