|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that VRVg (PR1) is at least as immunogenic as the reference vaccine, Verorab (PR2), in terms of seroconversion rate at D42, i.e. 14 days after the last vaccination of primary vaccination series.
|
|
E.2.2 | Secondary objectives of the trial |
To assess the clinical safety of VRVg after each vaccination when administered in a pre-exposure vaccination schedule with a booster at 12 months after the first vaccination in all subjects. To describe the immune response induced by VRVg 21 days after two vaccinations (D28) in a subset of 120 randomized subjects and 14 days after the last vaccination of the primary vaccination series, i.e. at D42, in all subjects. To describe antibody persistence at 6 and 12 months after the first vaccination in all subjects. To describe the immune response induced by VRVg 14 days after a booster vaccination administered 12 months after the first vaccination in all subjects.
