Primary Outcome Measures:
  • Geometric Mean Concentration of Rabies virus neutralizing antibody (RVNA)titers [ Time Frame: Day 14 after vaccination ] [ Designated as safety issue: No ]
    Non inferiority of the (2-1-1) postexposure schedule to that of the conventional (1-1-1-1-1) postexposure schedule, as measured by GMC of RVNA titers 14 days after vaccination in children and older adults.

  • Local and systemic reactions [ Time Frame: 7 days after vaccination ] [ Designated as safety issue: Yes ]
  • AEs/SAEs [ Time Frame: 43 days ] [ Designated as safety issue: Yes ]
    Safety and tolerability of the two schedules as measured by AEs/SAEs and solicited event reporting


Secondary Outcome Measures:
  • RVNA titers ≥ 0.5 IU/mL [ Time Frame: 14 days after first vaccination ] [ Designated as safety issue: No ]
    Percentages of subjects with RVNA titer ≥ 0.5 IU/mL 14 days after the first vaccination.

  • GMC and percentage of subjects with RVNA titer ≥ 0.5 IU/mL [ Time Frame: 42 days after first vaccination ] [ Designated as safety issue: No ]
