Brief Summary: This Phase 2(a) clinical trial is designed as a dose-blinded, block-randomized, multi-center study to select a dosage and schedule of rF1V vaccine for further studies based on the immune response up to Day 210. Additional immunogenicity and safety/reactogenicity data will be collected through Day 540. Selection of dosage and schedule will be based on GMCs and seroconversion rates for anti-F1, anti-V and anti-rF1V antibody titers. Approximately 400 healthy adult volunteers will be enrolled (100 per group) in this study.
Detailed Description: Primary Objective: To select a dosage and schedule of rF1V vaccine for further study based on the immune response to F1 and V antigens up to Day 210. Secondary Objectives: 1) To assess the safety of three injections of rF1V vaccine administered IM at two dosage levels. 2\) To assess the onset and duration of the humoral immune response to F1 and V antigens. 3\) To assess the humoral immune response to rF1V antigen. 4) To collect and store blood samples for future plague related research. Exploratory Objectives: To assess additional humoral immune responses to rF1V vaccine antigens.
