Study Endpoints

Primary Endpoints

Non-inferiority in Immune Response of the Zagreb Postexposure Schedule of Rabipur to That of the Conventional Essen Postexposure Schedule of Rabipur as Measured by GMC of RVNA Titer 14 Days After First Vaccination in Children Aged ≥6 to ≤17 Years.
Before vaccination (day 1) and 14 days after first vaccination (day 15)

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 14 days after first vaccination of Rabipur as per Zagreb (2-1-1) and Essen (1-1-1-1-1) postexposure schedule.

Non-inferiority in Immune Response of the Zagreb Postexposure Schedule of Rabipur to That of the Conventional Essen Postexposure Schedule of Rabipur as Measured by GMC of RVNA Titer 14 Days After the First Vaccination in Older Adults Aged ≥51 Years
Before vaccination (day 1) and 14 days after first vaccination (day 15).

Immunogenicity was measured as the GMCs of Rabies Virus Neutralizing Antibody (RVNA) titer , evaluated using the rapid fluorescent focus inhibition test, before vaccination and 14 days after first vaccination of Rabipur as per Zagreb (2-1-1) and Essen (1-1-1-1-1) postexposure schedule.

Number of Children Who Reported Solicited Local and Systemic Adverse Events After Any Vaccination of Rabipur
Days 1 to 7 postvaccination

Safety was assessed as the number of children who reported solicited local and systemic adverse events from day 1 up to and including day 7 after any vaccination of Rabipur as per Zagreb (2-1-1) and Essen (1-1-1-1-1) postexposure schedule.

Number of Older Adults Who Reported Solicited Local and Systemic Adverse Events After Any Vaccination of Rabipur
Days 1 to 7 postvaccination

Safety was assessed as the number of subjects who reported solicited local and systemic adverse events from day 1 up to and including day 7 after any vaccination of Rabipur as per Zagreb (2-1-1) and Essen (1-1-1-1-1) postexposure schedule.

Number of Children Who Reported Unsolicited Adverse Events (AEs)
From V1/day 1 (postvaccination) through V7/study termination day 43

The safety of Rabipur was assessed in terms of subjects(Children) exposed to study vaccine who reported all Unsolicited AEs (including serious adverse events \[SAE\]s and AEs leading to subject withdrawal) from V1/day 1 (postvaccination) through V7/study termination day 43.

Number of Older Adults Who Reported Unsolicited Adverse Events (AEs)
from V1/day 1 (postvaccination) through V7/study termination day 43

The safety of Rabipur was assessed in terms of subjects(Older Adults) exposed to study vaccine who reported all Unsolicited AEs (including serious adverse events \[SAE\]s and AEs leading to subject withdrawal) from V1/day 1 (postvaccination) through V7/study termination day 43.
