Pre-assignment details

During the screening the following steps occurred: check for inclusion/exclusion criteria, contraindications/precautions, medical history of the subjects and signing informed consent forms. Out of the 692 subjects enrolled in this study, one subject was eliminated due to not receiving vaccination, hence only 691 subject started the study.

Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms

Assessed solicited general symptoms were fatigue, gastrointestinal symptoms, headache and fever \[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)\]. 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. Results are presented across doses.

Time frame: During the 4-day (Days 0-3) period following each vaccination

Population: The analysis was performed on the Total Vaccinated cohort, which included all subjects with the vaccine administration documented.
