Primary Outcome Measures
NameTimeMethod
Geometric Mean Titer 21 Days After the Study Vaccination21 days after vaccination
Percentage of Participants With Seroconversion 21 Days After the Study Vaccination21 days after vaccination

Seroconversion rate was defined as the proportion of participants with a HI titer of less than 1:10 before vaccination achieving a HI antibody titer of 1:40 or more after vaccination, or with a HI titer of 1:10 or more before vaccination achieving a four-fold or greater increase in HI titer after vaccination.

Secondary Outcome Measures
NameTimeMethod
Frequency and Intensity of Local and Systemic Solicited Symptoms5 days after vaccination
New Onsets of Chronic Illness180 days after vaccination

A NOCI was defined as the diagnosis of a chronic medical condition where the symptoms commenced or worsened following exposure to the study vaccine and may have included those potentially controllable by medication (e.g., glaucoma, hypertension).

Frequency and Intensity of Unsolicited Adverse Events (UAEs)21 days after vaccination

Abbreviation UAE stands for Unsolicited Adverse Event.

Serious Adverse Events180 days after vaccination
Duration of Local and Systemic Solicited Symptoms5 days after vaccination
