- •Acute disease at the beginning of the study
- •Acute clinically significant changes in the lungs, cardiovascular system, liver or kidney function, identified by physical examination or laboratory tests
- •Pregnancy
- •Women who would like to fall pregnant during the period from the day of vaccination to 1 month thereafter
- •Known allergic reactions that might have been caused by one or more ingredients of the vaccine

Outcomes
Primary Outcomes
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.
Time Frame: On Day 21 (± 2) after vaccination
Descriptive comparison of the occurrence, severity and causal relationship to vaccination of solicited local and general symptoms
Time Frame: Within 4 days after vaccination
Secondary Outcomes
- 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)
