      The following administration site events will be solicited: pain, redness, swelling, lymphadenopathy (defined as localized axillary, cervical or supraclavicular swelling or tenderness ipsilateral to the injection arm).

    2. Percentage of participants reporting each solicited systemic event [From Day 1 to Day 7]

      The following systemic events will be solicited: fever, headache, myalgia, arthralgia, fatigue, chills. Fever is defined as temperature greater than or equal to (>=) 38 degree Celsius (°C)/100.4 degree Fahrenheit (°F) regardless the location of measurement. The route for measuring temperature can be oral, axillary or tympanic.

    3. Percentage of participants reporting unsolicited adverse events (AEs) [From Day 1 to Day 28]

      An unsolicited AE is defined as an AE that was either not included in the list of solicited events or could be included in the list of solicited events but with an onset outside the specified period of follow up for solicited events. Unsolicited AEs include both serious and non-serious AEs.

    4. Percentage of participants reporting serious adverse events (SAEs) [From Day 1 to Day 183]

      An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant, is an abnormal pregnancy outcome, or is a suspected transmission of any infectious agent via an authorized medicinal product.

    5. Percentage of participants reporting adverse events of special interest (AESIs) [From Day 1 to Day 183]

      The following events are considered as AESI in this study: severe hypersensitivity reactions within 24 hours after study intervention administration, myocarditis/pericarditis and potential immune-mediated diseases (pIMDs).

    6. Percentage of participants reporting medically attended events (MAEs) [From Day 1 to Day 183]

      MAE is defined as an AE that results in an unscheduled visit to a medical professional (e.g., physician's office visits, emergency room visits or hospitalization).

    7. Percentage of participants reporting a shift from a non-clinically significant laboratory value on Day 1 (pre-dose) to a clinically significant abnormal laboratory value on Day 8 (post-dose) and/or Day 29 (post-dose) for hematology and clinical chemistry [From Day 1 (pre-dose) to Day 8 (post-dose) and/or Day 29 (post-dose)]

      Clinically significant abnormal laboratory findings are those which are not associated with an underlying disease, unless judged by the investigator to be more severe than expected for the participants condition.

    8. Geometric mean titer (GMT) of antigen 1 antibody titer [At Day 29]

    9. Geometric mean increase (GMI) of antigen 1 antibody titer [From Day 1 to Day 29]

      GMI is defined as the geometric mean of the ratios of the post dosing titer over the Day 1 titer.

    5. GMT of antigen 2 antibody titer [At Day 92 and Day 183]

    6. GMI of antigen 2 antibody titer [From Day 1 to Day 92]
