Primary Outcome Measures

Name	Time	Method
GMT of the haemagglutination-inhibiting antibodies (HIA) and calculation of seroconversion factor, seroconversion rate and seroprotection rate checked against the CHMP criteria. The seroprotection power will be calculated as well.	On Day 21 (± 2) after vaccination
Descriptive comparison of the occurrence, severity and causal relationship to vaccination of solicited local and general symptoms	Within 4 days after vaccination

Secondary Outcome Measures

Name	Time	Method
Descriptive comparison of the occurrence and causal relationship to vaccination of unsolicited signs and symptoms	Within 30 days after vaccination
Descriptive comparison of the occurrence, severity and causal relationship to vaccination of any serious adverse events (SAEs)	During the entire study period.
Investigation of antibody persistence assessed by the criteria of the CHMP.	11, 19, 27 weeks after vaccination
