Brief Summary

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

The study has the following objectives:

Primary objective To evaluate the safety profile of an adjuvanted TB subunit vaccine administered in different antigen/adjuvant formulations at 0 and 2 months Secondary objective To determine the immunogenicity profile of an adjuvanted TB subunit vaccine administered in different antigen/adjuvant formulations at 0 and 2 months.
