Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Subjects With Solicited Local Symptoms	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.	During the 7-day (Days 0-6) post-vaccination period following each dose and across doses
Primary	Number of Subjects With Solicited General Symptoms	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.	During the 7-day (Days 0-6) post-vaccination period following each dose and across doses
Primary	Number of Subjects With Unsolicited Adverse Events (AEs)	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.	During the 30-day (Days 0-29) post-vaccination period
Primary	Number of Subjects With Serious Adverse Events (SAEs)	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.	During the entire study period (from Day 0 up to Day 210)
Primary	Number of Subjects With Normal Biochemical and Haematological Levels	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.	At Day 0, 7, 30, 37 and 60
Primary	Number of Subjects With Normal Haematological Levels	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.	At Day 0, 7, 30, 37 and 60
Primary	Number of Subjects With Biochemical and Haematological Above Normal Levels	Among biochemical and haematological parameters assessed were alanine aminotransferase [ALT], aspartate aminotransferase [AST], creatinine [CREA], haemoglobin [Hgb].
