Percentage of Participants With Local Reactions Within 7 Days After Administration of Study Intervention
Within 7 days after study intervention

Local reactions included redness, swelling and pain at the injection site collected in an electronic diary (e-diary) or case report form(CRF). Redness and swelling were measured and recorded in measuring device units. One measuring device unit=0.5 centimeter (cm). Redness and swelling reported in e-diary were graded as mild: greater than (\>) 2.0 cm to 5.0 cm, moderate: \>5.0 cm to 10.0 cm and severe \> 10 cm. Pain at injection site was graded as mild: did not interfere with activity; moderate: interfered with activity; and severe: prevented daily activity. Severity definition from CRF: mild (does not interfere)/moderate (interferes to some extent)/severe(interferes significantly) with the participant's usual function. Exact 2-sided 95% confidence interval (CI) was based on the Clopper and Pearson method.

Percentage of Participants With Systemic Events Within 7 Days After Administration of Study Intervention
Within 7 days after study intervention

Systemic events included fever, fatigue, headache, muscle pain and joint pain and were collected in an e-diary or CRF. Fever was defined as temperature greater than or equal to (\>=) 38.0 degrees Celsius (C) and categorized as \>=38.0 to 38.4 degrees C, \>38.4 to 38.9 degrees C, \>38.9 to 40.0 degrees C and \>40.0 degrees C. Fatigue, headache, muscle pain and joint pain were graded as mild: did not interfere with activity; moderate: some interference with activity and severe: prevented daily routine activities. Severity definition from the CRF: mild (does not interfere)/moderate(interferes to some extent)/severe(interferes significantly) with the participant's usual function. Exact 2-sided 95% CI was based on the Clopper and Pearson method.

Percentage of Participants With Adverse Events (AE) Within 1 Month After Administration of Study Intervention
Within 1 month after study intervention

An AE was defined as any untoward medical occurrence in a participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. Exact 2-sided 95% CI was based on the Clopper and Pearson method.

Percentage of Participants With Serious Adverse Events (SAE) Within 1 Month After Administration of Study Intervention
Within 1 month after study intervention

An SAE was defined as any untoward medical occurrence that, at any dose, met one or more of the following criteria - resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect and was a suspected transmission via a Pfizer product of an infectious agent, pathogenic or non-pathogenic and other important medical event. Exact 2-sided 95% CI was based on the Clopper and Pearson method.
