The assessed solicited administration site events are pain at administration site, redness at administration site, swelling at administration site and lymphadenopathy.

The assessed solicited systemic events are fever, headache, myalgia, arthralgia, fatigue, and chills. Fever is defined as temperature greater than or equal to (\>=)38 degrees Celsius (°C)/ 100.4 Fahrenheit (°F) regardless the location of measurement.

An unsolicited AE is 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 nonserious AEs.

An MAAE is defined as an unsolicited AE for which the participant receives medical attention such as 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, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant, abnormal pregnancy outcomes, is a suspected transmission of any infectious agent via an authorized medicinal product.

Events considered as AESIs are severe hypersensitivity reactions and myocarditis/pericarditis.

The assessed solicited administration site events are pain at administration site, redness at administration site, swelling at administration site and lymphadenopathy.

The assessed solicited systemic events are fever, headache, myalgia, arthralgia, fatigue, and chills. Fever is defined as temperature \>= 38°C/100.4°F regardless the location of measurement. The preferred location for measuring temperature is axillary.

Events considered as AESIs are severe hypersensitivity reactions, Aminotransferase (AT) elevation and myocarditis/pericarditis.

HI seroconversion is defined as a post-dose titer ≥1:40 in the serum of participants with pre-dose titer below 1:10 or as a ≥4-fold rise in post dose HI titers with pre- dose titer ≥1:10.
