Outcomes

Primary Outcome Measures

Number of Participants Who Experienced a Medically Attended Adverse Event (AE) Occurring in the Following 6 Months After Dose 2
Medically attended AEs were defined as AEs with medically attended visits that are not routine visits for physical examination or vaccination, such as visits for hospitalization, an emergency room visit, or an otherwise unscheduled visit to or from medical personnel (medical doctor) for any reason. The Investigator assessed the relationship between trial vaccine and occurrence of each AE.
Number of Participants Who Experienced a Serious Adverse Event (SAE)
An SAE was defined as any untoward medical occurrence that, at any dose: Resulted in death. Was life-threatening. Required inpatient hospitalization or prolongation of existing hospitalization. Resulted in persistent disability/incapacity. Was a congenital anomaly/birth defect in the offspring of the participant. Was an important medical event. The Investigator assessed the relationship between trial vaccine and occurrence of each AE.
Intensity of SAEs Per the Investigator's Assessment
An SAE was defined as any untoward medical occurrence that, at any dose: Resulted in death. Was life-threatening. Required inpatient hospitalization or prolongation of existing hospitalization. Resulted in persistent disability/incapacity. Was a congenital anomaly/birth defect in the offspring of the participant. Was an important medical event. The Investigator made an assessment of intensity for each AE reported during the trial and assigned it to one of the following categories: Mild: an event that was easily tolerated by the participant, causing minimal discomfort and not interfering with everyday activities. Moderate: an event that caused sufficient discomfort to interfere with normal everyday activities. Severe: an event that prevented normal everyday activities.
Number of Participants Who Experienced an Adverse Event of Special Interest (AESI) Occurring in the Following 1 Year After Dose 2
The following events were considered and collected as AESI throughout the trial: AEs with a suspected immune-mediated etiology. Other AEs relevant to SARS-CoV-2 vaccine development or the target disease. COVID-19. The Investigator assessed the relationship between trial vaccine and occurrence of each AE.
Number of Participants Who Experienced Death Due to SAE
An SAE was defined as any untoward medical occurrence that, at any dose: Resulted in death. Was life-threatening. Required inpatient hospitalization or prolongation of existing hospitalization. Resulted in persistent disability/incapacity. Was a congenital anomaly/birth defect in the offspring of the participant. Was an important medical event.
Number of Participants Who Experienced an AE Leading to Vaccine Withdrawal Occurring in the Following 1 Year After Dose 2
Number of Participants Who Experienced an AE Leading to Trial Discontinuation Occurring in the Following 1 Year After Dose 2

Occurrence of Seroconversion for SARS-CoV-2 Receptor-Binding Domain (RBD) of Spike Protein Antibodies (IgG) on Day 29 and Day 43
Titers of IgG antibodies directed against the SARS-CoV-2 RBD of Spike Protein antigen were measured by enzyme-linked immunosorbent assay (ELISA). Percentage with 95% confidence interval (CI) of participants for whom a seroconversion was observed is presented by group. Seroconversion was defined as a fold increase above 1 in SARS-CoV-2 Spike Protein RBD IgG antibody levels in participants seronegative at Baseline. Participants who tested positive for COVID-19 had their data included up to the point of a positive test result. Participants who received a licensed/authorized vaccine were censored at the day after receiving the licensed/authorized vaccine.
SARS-CoV-2 RBD of Spike Protein Antibody (IgG) Levels on Days 1, 29 and 43
Titers of IgG antibodies directed against the SARS-CoV-2 RBD of Spike Protein antigen were measured by ELISA and expressed as geometric mean of titers (GMT) with 95% CI, by group. Individual values below the lower limit of quantification (LLOQ) were set to half of the LLOQ. Participants who tested positive for COVID-19 had their data included up to the point of a positive test result. Participants who received a licensed/authorized vaccine were censored at the day after receiving the licensed/authorized vaccine.
