Geometric Mean Rabies Virus Neutralizing Antibody (RVNA) Concentration in Each of the Zagreb and Essen Groups on Study Day 14
Zeitfenster: On Day 0 and Day 14
|
Immunogenicity was measured as the geometric mean concentrations (GMCs) of rabies virus neutralizing antibody (RVNA) titer , evaluated using the rapid fluorescent focus inhibition test, before vaccination and on study day 14 as per Zagreb (2-1-1) and Essen (1-1-1-1-1) postexposure schedule

Percentages of Subjects With Anti-RVNA Titer ≥0.5 IU/mL in Zagreb and Essen Groups at Days 7, 14 and 42
Zeitfenster: Study day 7, 14 and 42
|
Immunogenicity was measured as the percentage of subjects who achieved anti-RVNA titer ≥0.5 IU/mL, at days 0, 7, 14 and 42 as per Zagreb (2-1-1) and Essen (1-1-1-1-1) postexposure schedule.

Ratio of GMCs in Study Groups (Zagreb/Essen Schedules) on Days 7 and 42 as Measured by RVNA Geometric Mean Concentrations
Zeitfenster: Day 0, Day 7, Day 14 and Day 42
|
Immunogenicity was measured as the ratio of GMCs of RVNA titer , evaluated using the rapid fluorescent focus inhibition test, on Days 7 and 42 as per Zagreb (2-1-1) and Essen (1-1-1-1-1) postexposure schedules

Percentages of Subjects Reporting Adverse Events (AEs)
Zeitfenster: All reported SAEs and medically attended AEs or AEs that resulted in the premature withdrawal of subjects were collected up to 42 days after first vaccination. Adverse events were collected throughout the study period
|
Adverse events (AEs) were collected for 7 days following administration of each study vaccination or until time of next vaccination (whichever occurred sooner).
All reported SAEs and medically attended AEs or AEs that resulted in the premature withdrawal of subjects during the study were collected throughout the study period and all AEs were unsolicited.
