Immunogenicity and Safety of Verorab® in a "One-week" Intradermal Post-exposure Prophylaxis Regimen

The purpose of this study is to assess the 4-site "one-week" post-exposure prophylaxis (PEP) regimen as a possible alternative to the 2-site updated Thai Red Cross (TRC) PEP regimen. Primary objective: * To demonstrate that PEP using the new "one-week, 4-site" (4-4-4-0-0) intradermal (ID) vaccination regimen is non-inferior to PEP using the updated TRC (2-2-2-0-2) ID vaccination regimen. Secondary objectives: * Primary immunization: To describe the immune response in each group at Day 0, Day 14 and Day 90. * Antibody persistence: To describe rabies virus-neutralizing antibody persistence during the 5 years after completion of PEP in each group. * Booster vaccination: To describe the immune response induced by a single-visit 4-site intradermal booster vaccination in each group at Year 5. * Safety: To describe the safety profile of each group after the primary and booster vaccinations.
