Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This Phase 2 study is a double blind, placebo-controlled, randomized, multicenter investigation of rBV A/B-40 vaccine or placebo in healthy adults, using two different three-dose dosing schedules.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study includes 18 months (547 days) of follow-up after the first vaccination for all randomized volunteers who receive at least one vaccination. Analysis of cumulative data collected through Day 547 ± 14 days will be reported in the final clinical study report.
