E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To demonstrate that VRVg is at least as immunogenic as the reference vaccine, Verorab vaccine, in terms of proportion of subjects with a rabies virus neutralizing antibody (RVNA) titer ≥ 0.5 international units (IU)/mL at D14, i.e. before the fourth injection, in subjects aged 10 to 17 years and in subjects aged 18 years and over. |
|
E.2.2 | Secondary objectives of the trial |
• To assess the clinical safety of VRVg after each injection when administered in a post-exposure vaccination schedule in each respective age group and overall • To describe the immune response induced by VRVg before the fourth injection (D14) and 14 days after the last injection (D42) in each respective age group and overall |
