This study was designed to evaluate the safety and immunogenicity of Rabipur Zagreb (2-1-1) and Rabipur Essen (1-1-1-1-1) simulated post exposure vaccination schedules in Chinese children and older adults. Subjects randomized to Group 1 (Zagreb) will receive 4 doses of rabies vaccine Day 1 (2 doses), and on Day 8 and Day 22. Subjects randomized to Group 2 (Essen) will receive 5 doses of rabies vaccine on Days 1, 4, 8, 15, and 29. First vaccine will be administered on study Day 1.~240 children and 400 older adults, a total of 640, is planned to be enrolled into the study. Subjects will be divided further into age subsets of equal numbers within each age cohort (children: 6 to 11 years of age and 12 to 17 years of age; older adults: 51 to 60 years of age and 61 years of age and older. Within each age subset, subjects will be assigned randomly in a 1:1 ratio.~The primary objective is to establish the non-inferiority of the Rabipur Zagreb (2-1-1) schedule relative to the conventional Rabipur Essen (1-1-1-1-1) schedule based on geometric mean titers (GMC), and the secondary objective is to assess the percent of subjects with rabies virus neutralizing titer ≥ 0.5 IU/mL 14 days after the first vaccinations (study Day 15) for each schedule and age cohort
This study was designed to evaluate the safety and immunogenicity of two simulated postexposure rabies vaccination schedules (Zagreb 2-1-1 and Essen 1-1-1-1-1) in Chinese children and older adults.
