E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1) To demonstrate that a single dose of VARIVAX™ PE34 process induces varicella-zoster virus (VZV) antibody responses 6 weeks Postvaccination 1 that are noninferior to those induced by VARIVAX™ 2016 commercial product.
2) To demonstrate that a single dose of VARIVAX™ PE34 process induces an acceptable VZV antibody response 6 weeks Postvaccination 1.
|
|
E.2.2 | Secondary objectives of the trial |
1) To assess the safety and tolerability of the first and second doses of VARIVAX™ PE34 process.
2) To summarize the VZV antibody responses after a single dose of VARIVAX™ PE34 process and after a single dose of VARIVAX™ (2016 commercial product).
