Number of Participants Reporting Any Solicited Administration Site Events After the First Vaccination Administered on Day 1
Tidsramme: From Day 1 to Day 7
|
The solicited administration site events include tenderness (administration site pain), erythema (redness), induration and swelling.
Any solicited administration site events = occurrence of the event regardless of intensity grade.
Data for solicited administration site events is presented for each intervention administered in each arm group.

Number of Participants Reporting Any Solicited Systemic Events After the First Vaccination Administered on Day 1
Tidsramme: From Day 1 to Day 7

The solicited systemic events included diarrhoea, drowsiness (somnolence), fever (pyrexia), irritability/fussiness, loss of appetite, and vomiting.
Fever is defined as temperature >38.0°C/100.4°F.
Any solicited systemic events = occurrence of the event regardless of intensity grade.

Number of Participants Reporting MAAEs, SAEs, AEs Leading to Withdrawal, and AESIs
Tidsramme: From Day 1 to Day 481
|
MAAEs are defined as symptoms or illnesses requiring a hospitalization, or an emergency room visit, or visit to/by a health care provider.
An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization or results in disability/incapacity.
AESIs are predefined (serious or non-serious) AEs of scientific and medical concern specific to the product or program, for which ongoing monitoring and rapid communication by the investigator to the sponsor can be appropriate, because such an event might warrant further investigation in order to characterize and understand it.
AEs leading to withdrawal are defined as AEs due which the participant is considered to have withdrawn from the study as no new study procedure has been performed or no new information has been collected for them since the date of withdrawal/last contact.
