• Over the age of 65 Years.
• Vaccinated against tularemia within the last 10 years or had a documented, confirmed tularemia infection.
• Clinically significant abnormal lab results including evidence of hepatitis C, hepatitis B carrier state, or elevated liver function tests (two times the normal range or at the discretion of the PI).
• Personal history of an immunodeficiency or current treatment with an oral or intravenous immunosuppressive medication.
• Confirmed HIV* infection.
• A medical condition that, in the judgment of the Principal Investigator (PI), would impact subject safety.
