Percentage of Participants With Local Reactions Within 7 Days After Vaccination 1
Local reactions were recorded using an electronic diary. Local reactions included redness, swelling and pain at the injection site. Redness and swelling were measured and recorded in measuring device units. 1 measuring device unit =0.5 centimeter (cm). Redness and swelling were graded as mild (0.5 to 2.0 centimeter \[cm\]), moderate (greater than \[\>\] 2.0 to 7.0 cm) and severe (\>7.0 cm). Pain at injection site was graded as mild (hurt if gently touched example, whimpered, winced, protested, or withdrew), moderate (hurt if gently touched, with crying), and severe (caused limitation of limb movement).
Time frame: Within 7 days after Vaccination 1
Percentage of Participants With Local Reactions Within 7 Days After Vaccination 2
Local reactions were recorded using an electronic diary. Local reactions included redness, swelling and pain at the injection site. Redness and swelling were measured and recorded in measuring device units. 1 measuring device unit =0.5 cm. Redness and swelling were graded as mild (0.5 to 2.0 cm), moderate (\>2.0 to 7.0 cm) and severe (\>7.0 cm). Pain at injection site was graded as mild (hurt if gently touched example, whimpered, winced, protested, or withdrew), moderate (hurt if gently touched, with crying), and severe (caused limitation of limb movement).
Time frame: Within 7 days after Vaccination 2
Percentage of Participants With Local Reactions Within 7 Days After Vaccination 3
Local reactions were recorded using an electronic diary. Local reactions included redness, swelling and pain at the injection site. Redness and swelling were measured and recorded in measuring device units. 1 measuring device unit =0.5 cm. Redness and swelling were graded as mild (0.5 to 2.0 cm), moderate (\>2.0 to 7.0 cm) and severe (\>7.0 cm). Pain at injection site was graded as mild (hurt if gently touched example, whimpered, winced, protested, or withdrew), moderate (hurt if gently touched, with crying), and severe (caused limitation of limb movement).

Percentage of Participants With Systemic Events Within 7 Days After Vaccination 1
Systemic events included fever, decreased appetite, drowsiness, irritability and were recorded by using an electronic diary. Fever was defined as greater than or equal to (\>=) 38.0 degree Celsius (C) and categorized to \>=38.0 to 38.4 degree C, \>38.4 to 38.9 degree C, \>38.9 to 40.0 degree C and \>40.0 degree C. Decreased appetite was graded as mild (decreased interest in eating), moderate (decreased oral intake) and severe (refusal to feed). Drowsiness was graded as mild (increased or prolonged sleeping bouts), moderate (slightly subdued, interfered with daily activity) and severe (disabled, not interested in usual daily activity). Irritability was graded as mild (easily consolable), moderate (required increased attention) and severe (inconsolable; crying could not be comforted).
