Primary Outcome Measures:
  • Number of Subjects With Solicited Local Symptoms [ Time Frame: During the 7-day (Days 0-6) post-vaccination period following each dose and across doses ]
    Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site. Relationship analysis was not performed.

  • Number of Subjects With Solicited General Symptoms [ Time Frame: During the 7-day (Days 0-6) post-vaccination period following each dose and across doses ]
    Assessed solicited general symptoms were fatigue, temperature [defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)], gastrointestinal symptoms (gastro) [nausea, vomiting, diarrhoea and/or abdominal pain], headache, malaise and myalgia. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever ≥ 39.5 °C. Related = symptom assessed by the investigator as related to the vaccination.

  • Number of Subjects With Unsolicited Adverse Events (AEs) [ Time Frame: During the 30-day (Days 0-29) post-vaccination period ]
    An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset out-side the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.

  • Number of Subjects With Serious Adverse Events (SAEs) [ Time Frame: During the entire study period (from Day 0 up to Day 210) ]
    Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

  • Number of Subjects With Normal Biochemical and Haematological Levels [ Time Frame: At Day 0, 7, 30, 37 and 60 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], creatinine [CREA], haemoglobin [Hgb]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were - normal, below and above.

  • Number of Subjects With Normal Haematological Levels [ Time Frame: At Day 0, 7, 30, 37 and 60 ]

    Among haematological parameters assessed were platelets [PLA], red blood cells [RBC] and white blood cells [WBC].

    Levels of haematological parameters assessed in terms of normal laboratory values were - normal, below and above.


  • Number of Subjects With Biochemical and Haematological Above Normal Levels [ Time Frame: At Day 0, 7, 30, 37 and 60 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], creatinine [CREA], haemoglobin [Hgb]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were - normal, below and above.

  • Number of Subjects With Haematological Levels Above Normal [ Time Frame: At Day 0, 7, 30, 37 and 60 ]

    Among haematological parameters assessed were platelets [PLA], red blood cells [RBC] and white blood cells [WBC].

    Levels of haematological parameters assessed in terms of normal laboratory values were - normal, below and above.


  • Number of Subjects With Biochemical and Haematological Below Normal Levels [ Time Frame: At Day 0, 7, 30, 37 and 60 ]
    Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], creatinine [CREA], haemoglobin [Hgb]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were - normal, below and above.

  • Number of Subjects With Haematological Levels Below Normal [ Time Frame: At Day 0, 7, 30, 37 and 60 ]

    Among haematological parameters assessed were platelets [PLA], red blood cells [RBC] and white blood cells [WBC].

    Levels of haematological parameters assessed in terms of normal laboratory values were - normal, below and above.



Secondary Outcome Measures:
  • Frequency of Mycobacterium Tuberculosis Fusion Protein (M72) Specific Cluster of Differentiation 4/8 (CD4/8+) T Cells Expressing at Least Two Different Cytokines [ Time Frame: At Day 0, 7, 30, 37, 60 and 210 ]
    Among cytokines expressed were interleukin-2 [IL-2], interferon-gamma [IFN-γ], tumour necrosis factor-alpha [TNF-α] and cluster of differentiation 40-ligand [CD40-L]. Analysis of cytokines expression was done by means of in vitro flow cytometry, using intracellular cytokine staining (ICS).

  • Frequency of M72 Specific CD4+ T Cells Expressing Any Combination of Cytokines [ Time Frame: At Day 0, 7, 30, 37, 60 and 210 ]
    Among cytokines expressed were interleukin-2 [IL-2], interferon-gamma [IFN-γ], tumour necrosis factor-alpha [TNF-α] and cluster of differentiation 40-ligand [CD40-L], after background reduction stimulated by M72. Analysis of cytokines expression was done by means of in vitro flow cytometry, using intracellular cytokine staining (ICS).

  • Frequency of M72 Specific CD8+ T Cells Expressing Any Combination of Cytokines [ Time Frame: At Day 0, 7, 30, 37, 60 and 210 ]
    Among cytokines expressed were interleukin-2 [IL-2], interferon-gamma [IFN-γ], tumour necrosis factor-alpha [TNF-α] and cluster of differentiation 40-ligand [CD40-L], after background reduction stimulated by M72. Analysis of cytokines expression was done by means of in vitro flow cytometry, using intracellular cytokine staining (ICS).

  • Anti-M72 Specific Antibody Concentrations [ Time Frame: At Day 0, 30, 60 and 210 ]
    Antibody concentrations given in Enzyme-Linked Immunosorbent Assay (ELISA) units per millilitre (EL.U/mL) were expressed as Geometric Mean Concentrations (GMCs).
