RandomizedParallel-groupQuadruple-blindPrevention

Summary

Primary Objective: To demonstrate that Purified Vero Rabies Vaccine - Serum Free Vaccine generation 2 (VRVg-2) was non-inferior to Verorab and Imovax Rabies vaccines when co-administered with human rabies immunoglobulin (HRIG), in terms of proportion of participants achieving a rabies virus neutralizing antibody (RVNA) titer greater than or equal to (\>=) 0.5 international units per milliliter (IU/mL) at Day 28, i.e., 14 days after the fourth vaccine injection. Secondary Objective: * To describe the safety profile of VRVg-2 versus Verorab and Imovax Rabies vaccines when co-administered with HRIG, as well as that of VRVg-2, after each vaccine injection. * To demonstrate that the proportion of participants in the VRVg-2 + HRIG group achieving an RVNA titer \>= 0.5 IU/mL at Day 28 was at least 95 percent (%). * To describe the immune response induced by VRVg-2 versus Verorab and Imovax Rabies vaccines when co-administered with HRIG, as well as that induced by VRVg-2, at Day 14 (7 days after the third injection), at Day 28 (14 days after the fourth injection) and at Day 42 (14 days after the last injection).
