Pain at injection site was graded as mild: did not interfere with activity; moderate: interfered with activity and severe: prevented daily activity. Redness and swelling were measured and recorded in measuring device units, where 1 measuring device unit=0.5 centimeter (cm) and graded as mild: 2.5 cm to 5.0 cm; moderate: greater than (\>) 5.0 cm to 10.0 cm; severe: \> 10 cm.

Systemic events included fever, fatigue, headache, vomiting, diarrhea, chills, new/worsened muscle pain and joint pain. These were recorded by participants in an e-diary. Fever was defined as oral temperature greater than or equal to (\>=) 38.0 degrees Celsius (deg C) and categorized as mild: \>=38.0 to 38.4 deg C, moderate: \>38.4 to 38.9 deg C and severe: \>38.9 to 40.0 deg C. Vomiting was categorized as mild: 1-2 times in 24 hours (h); moderate: \>2 times in 24h; severe: required intravenous (IV) hydration.
