Outcomes

Primary Outcome Measures

Seroconversion

Seroconversion rate was defined as the number of subjects with ≥4-fold increase in haemagglutination inhibition (HI) antibody titer and with a titer of ≥1:40

Seroprotection

Seroprotection rate, defined as the number of subjects with HI antibody titer ≥1:40

Fold Increase in Geometric Mean Titer (GMT)

GMT-fold increase - calculated as the GMT on Day 22 divided by the baseline GMT value

Secondary Outcome Measures

Safety: Numbers of Subjects Reporting Solicited Local Adverse Events

Safety assessments are made by the investigator at baseline and on Days 8, 15 and 22 as well as by the subjects themselves (in a Subject Diary) for the 4-day period immediately following vaccination.

Numbers of Subjects Reporting Solicited Systemic Adverse Events

Safety assessments are made by the investigator at baseline and on Days 8, 15 and 22 as well as by the subjects themselves (in a Subject Diary) for the 4-day period immediately following vaccination.
