Percentage of Participants With Local Reactions Within 7 Days After Dose 3

时间窗: Within 7 Days after Dose 3

Local reactions included pain at injection site, redness and swelling, recorded by parent's/legal guardians of participants in an e-diary. Redness and swelling were measured and recorded in measuring device (caliper) units. 1 measuring device unit =0.5 cm. Redness and swelling were graded as mild: \>0.0 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; moderate: hurt if gently touched with crying; severe: limited limb movement.
