Study Endpoints
Primary Endpoints
Number of Subjects With Solicited Local Symptoms
During the 7-day (Days 0-6) post-vaccination period, following each dose and across doses

Assessed solicited local symptoms included 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
During the 7-day (Days 0-6) post-vaccination period, following each dose and across doses

Assessed solicited general symptoms included 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 ≥ 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.

Number of Subjects With Unsolicited Adverse Events (AEs)
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 outside 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)
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 Different Biochemical and Haematological Levels
At Day 0

Among biochemical and haematological parameters assessed were alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\], basophils \[BAS\], creatinine \[CREA\], eosinophils \[EOS\], haematocrit \[Hct\], haemoglobin \[Hgb\], lymphocytes \[LYM\], monocytes \[MON\], neutrophils \[NEU\], platelets \[PLA\], red blood cells \[RBC\] and white blood cells \[WBC\]. Levels of haematological/biochemical parameters assessed in terms of normal laboratory values were- normal, below and above.

Secondary Endpoints
Frequency of Mycobacterium Tuberculosis Fusion Protein (M72) Specific Cluster of Differentiation 4/8 (CD4/8+) T Cells Expressing at Least Two Different Cytokines
At Day 0, 30, 60 and 210
Frequency of M72 Specific CD4/8+ T Cells Expressing at Least One Cytokine and Another Signal Molecule
At Day 0, 30, 60 and 210
Anti-M72 Specific Antibody Concentrations
