The solicited administration site events include erythema (redness), pain and swelling. Any solicited administration site AEs = occurrence of the symptom regardless of intensity grade.

The solicited systemic events include arthralgia (joint pain), fatigue (tiredness), headache, myalgia (muscle pain), and fever \[temperature \>=38.0-degree Celsius (°C)\]. Any solicited systemic AEs = occurrence of the symptom regardless of intensity grade.

An unsolicited AE is an AE that was not included in the list of solicited events. Also, any solicited symptom with onset outside the specified period of follow-up for solicited symptoms is to be reported as an unsolicited AE. Any = occurrence of the symptom regardless of intensity grade.

An unsolicited AE is an AE that was not included in the list of solicited events. Also, any solicited symptom with onset outside the specified period of follow-up for solicited symptoms is to be reported as an unsolicited AE. Any = occurrence of the symptom regardless of intensity grade.

MAEs are defined as AEs requiring medically attended visits, such as visits for hospitalization, an emergency room visit, or an otherwise unscheduled visit to or from medical personnel (medical doctor) for any reason. Any = occurrence of the symptom regardless of intensity grade.

An SAE is defined as any untoward medical occurrence that: resulted in death, was life threatening, required hospitalization or prolongation of hospitalization, resulted in disability/incapacity or was a congenital anomaly/birth defect in the offspring of a study subject. Any = occurrence of the symptom regardless of intensity grade.

plMDs are defined as a subset of adverse events of special interest (AESI) that include autoimmune diseases and other inflammatory or neurologic disorders that may or may not have an autoimmune etiology. Newly diagnosed pIMDs are categorized as new-onset conditions if they start following the administration of the study intervention. Any = occurrence of the symptom regardless of intensity grade.

Exacerbation of pre-existing pIMDs is categorized as an exacerbation of a pre-existing chronic condition if the condition worsened following the administration of the study intervention.

The safety laboratory data included haematological parameters (hemoglobin, white blood cells (WBC), platelets), and chemical parameters (Alanine Aminotransferase \[ALT\], Aspartate Aminotransferase \[AST\], Creatinine, Urea nitrogen). Below = value below the laboratory reference range defined for the specified visit and laboratory parameter; Within = value within the laboratory reference range defined for the specified visit and laboratory parameter; Above = value above the laboratory reference range defined for the specified visit and laboratory parameter.
