Official title

A Phase 3, Double-Blind, Randomized, Multicenter, Controlled Study to Evaluate the Immunogenicity, Safety, and Tolerability of VARIVAX™ Passage Extension 34 (PE34) Process Administered Concomitantly With M-M-R™ II

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will evaluate the immunogenicity, safety, and tolerability of VARIVAX® (Varicella Virus Vaccine Live) manufactured with a new passage extension (PE34) process compared with the VARIVAX® 2016 commercial process. The primary hypotheses being tested are that antibody response rate and mean antibody titer induced at 6 weeks after a single vaccination by VARIVAX® PE34 Process are non-inferior to those induced by VARIVAX® 2016 commercial process, and that antibody response rate induced by VARIVAX® PE34 Process is acceptable.
