简要总结
This is a Phase 2, randomized, active-controlled, open-label study with a 3-arm parallel design. Healthy 2-month old infants (42 to 98 days of age) with no history of pneumococcal vaccination will be randomized in a 1:1:1 ratio to receive a 4-dose series of: multivalent pneumococcal conjugate vaccine coadministered with Prevnar 13 (Group 1); multivalent pneumococcal conjugate vaccine given 1 month after Prevnar 13 (Group 2); or Prevnar 13 with a single dose of multivalent pneumococcal conjugate vaccine (Group 3).

主要结局
Percentage of Participants With Local Reactions Within 7 Days After Dose 2
时间窗: Within 7 Days After Dose 2
Local reactions were recorded using an electronic diary by participant's LAR. 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 (\>0.0 to 2.0 cm), moderate (\>2.0 to 7.0 cm) and severe (\>7 cm). Pain at injection site was graded as mild (hurt if gently touched), moderate (hurt if gently touched, with crying), and severe (caused limitation of limb movement).
