E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the safety and tolerability of Rabies and JE vaccines given concomitantly or alone and according to either of 2 schedules for pre-exposure prophylaxis
Immunogenicity:
Primary:
1. To establish non-inferiority of the immune response of Rabies vaccine (administered concomitantly with JE vaccine) accelerated schedule as compared to conventional schedule.
2. To establish non-inferiority of the immune response of JE vaccine (administered concomitantly with Rabies vaccine), accelerated schedule as compared to conventional schedule. |
|
E.2.2 | Secondary objectives of the trial |
1. Establish non-inferiority of the Rabies vaccine immune response (with JE vaccine) versus Rabies vaccine alone in a Conventional vaccination schedule. 2. Establish non-inferiority of the immune response of JE vaccine (with Rabies vaccine) versus JE vaccine alone in a Conventional vaccination schedule. 3. Establish non-inferiority of the immune response of Rabies vaccine (with JE vaccine) given in an Accelerated schedule versus Rabies vaccine alone in a Conventional vaccination schedule. 4. Establish non-inferiority of the immune response of JE vaccine (with Rabies vaccine) in an Accelerated schedule versus JE vaccine alone in a Conventional vaccination schedule. 5. Evaluate antibody response kinetics in groups receiving Rabies vaccine measured by rapid fluorescent focus inhibition test (RFFIT) on Days 8, 15, 36, 91, 181 and 366. 6. Evaluate antibody response kinetics in groups receiving JE vaccine.
