- Fever is defined as oral or axillary temperature ≥ 37.5°C. The preferred route for recording temperature in this study will be oral.
- Subjects with acute disease and/ or fever at the time of Screening may be enrolled at a later date if enrolment is still open. Subjects with a minor illness without fever may be enrolled at the discretion of the investigator.
Pregnant or lactating female.
Current alcoholism and/or drug abuse.
Other condition which the investigator judges may put the safety of the subject at risk through study participation or which may interfere with the study findings.

Primary Outcome Measures

Name	Time	Method
Number of Subjects With Any Solicited Local Adverse Events (AEs).	During a 7-day follow-up period (from Day 0 to Day 6) after first dose.	Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.
Number of Subjects With Any Unsolicited AEs.	During the 30-day follow-up period (from Day 0 to Day 29) following the first dose.	Assessed unsolicited AEs covered 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. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. Any = occurrence of the symptom regardless of intensity grade or relation to vaccination.
Number of Subjects Reporting Any Potential Immune-mediated Diseases (pIMDs).	From first vaccination (Day 0) up to study conclusion (Day 450).	pIMDs are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune aetiology.
Number of Subjects With Any Solicited Local AEs.	During a 7-day follow-up period (from Day 60 to Day 66) after second dose.	Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.
Number of Subjects With Any Solicited General AEs	During a 7-day follow-up period (from Day 60 to Day 66) following the second dose.	Assessed solicited general symptoms are fatigue, gastrointestinal symptoms (included nausea, vomiting, diarrhoea and/or abdominal pain), headache, fever (defined as oral temperature equal to or above 37.5 °C). Any = occurrence of the symptom regardless of intensity grade.
Number of Subjects With Any Unsolicited AEs	During the 30-day follow-up period (from Day 60 to Day 89) following the second dose.	Assessed unsolicited AEs covered 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. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. Any = occurrence of the symptom regardless of intensity grade or relation to vaccination.
Number of Subjects With Any Solicited General AEs.	During a 7-day follow-up period (from Day 0 to Day 6) following the first dose.	Assessed solicited general symptoms are fatigue, gastrointestinal symptoms (included nausea, vomiting, diarrhoea and/or abdominal pain), headache, fever \[defined as oral temperature equal to or above 37.5 degrees Celsius (°C)\]. Any = occurrence of the symptom regardless of intensity grade.
Number of Subjects With Each Haematological/ Biochemical Laboratory Abnormality.	At Day 450.	Assessed haematological parameters are complete blood cell count: Leukocytes \[white blood cells (WBC)\], differential count (basophils, eosinophils, lymphocytes, monocytes, neutrophils), platelets count, and hemoglobin level below or above the normal laboratory ranges tabulated by time point. Assessed biochemical parameters are alanine aminotransferase (ALT), aspartate aminotransferase (AST) or creatinine below or above the normal laboratory ranges tabulated by time point.
Number of Subjects With Any Serious Adverse Events (SAEs).	From first vaccination (Day 0) up to study conclusion (Day 450).	SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity or are a congenital anomaly/ birth defect in the offspring of a study subject.
