Outcome Measures
Primary Outcomes (2)
Number of participants that presented seroconversion post injection
* Seroconvertion is defined as: prevaccination Hemagglutination-inhibition test (HI) antibody titer ≤1:10 and postvaccination HI antibody titer ≥1:40, or prevaccination HI antibody titer ≥1:10 and a postvaccination increase by a factor of four or more. * Participants will be collected blood post first study injection, when blood samples will be taken for HI testing
30 days after inoculation
Geometric mean of Hemagglutination-inhibition titre post first study injection
* Geometric mean of Hemagglutination-inhibition test titre will be calculated for the different groups of participants post first study injection. * Participants will be collected blood post first study injection, when blood samples will be taken for HI testing.
30 days after inoculation
Secondary Outcomes (2)
Number of participants that presented seroprotection post injection
30 days after inoculation
Number of Subjects Reporting Solicited and Unsolicited Adverse Events (AEs)
Continuous observation for 30 days after two inoculations
