Exclusion Criteria:

1. Acute illness at the time of randomization
2. Oral temperature ≥37.5°C at the time of randomization

3. Clinically significant abnormal laboratory values for any of the following screening laboratory parameters, per local laboratory normal ranges from blood collected within 30 days prior to Study Day 0 randomization as follows:

   • hemoglobin, hematocrit, absolute neutrophil count, absolute lymphocyte count, or platelet count below lower limit of normal (LLN)
   • white blood cell count above upper limit of normal (ULN) or below LLN (i.e., must be within normal limits)
   • ALT, AST, total bilirubin, alkaline phosphatase, creatinine, or blood urea nitrogen (BUN) above ULN
4. Evidence of systemic or local disease process on screening urinalysis
5. Evidence of significant active infection
6. History of treatment for active or latent tuberculosis or evidence of active tuberculosis
7. Shared a residence within the last year prior to randomization with an individual on anti-tuberculosis treatment or with culture or smear positive tuberculosis
8. History of autoimmune disease or immunosuppression
9. Used immunosuppressive medication within 42 days before randomization (inhaled and topical corticosteroids are permitted)
10. Received immunoglobulin or blood products within 42 days before randomization
11. Received any investigational drug therapy or investigational vaccine within 182 days before randomization, or planned participation in any other investigational study during the study period
12. Received investigational Mtb vaccine at any time prior to randomization
13. Received a live vaccine within past 4 weeks or a killed vaccine within past 2 weeks prior to randomization.
14. Unable to discontinue current chronic prescription drug therapy that can be hepatotoxic or toxic to the bone marrow or kidneys.
15. History or laboratory evidence of immunodeficiency state including but not limited to any laboratory indication of HIV-1 infection
16. History of allergic disease or reactions (including allergy to kanamycin-related antibiotics, allergic reaction to eggs, and severe eczema), likely to be exacerbated by any component of the study vaccine
17. Previous medical history that may compromise the safety of the participant in the study, including but not limited to: severe impairment of pulmonary function from pulmonary disease; chronic illness with signs of cardiac or renal failure; suspected progressive neurological disease; or uncontrolled epilepsy
18. Evidence of chronic hepatitis (e.g., hepatitis B surface antigen or hepatitis C antibody)
19. Chronic heavy ethanol intake which, in the opinion of the investigator, may compromise the safety of the participant or interfere with the evaluation of the safety of the vaccine
20. Cannabis smoking 3 or more days per week
21. Positive urine test for illicit drugs (opiates, cocaine, amphetamines)
22. History or evidence on physical examination of any systemic disease or any acute or chronic illness that, in the opinion of the investigator, may interfere with the evaluation of the safety or immunogenicity of the vaccine
23. All female participants: currently pregnant or lactating/nursing; or positive urine pregnancy test during screening or on the day of study injection
24. Received a tuberculin skin test within 3 months (90 days) prior to Study Day 0
25. Any current medical, psychiatric, occupational, or substance abuse problems that, in the opinion of the investigator, will make it unlikely that the participant will comply with the protocol or may compromise the safety of the participant
