Clinical Trial Summary

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).

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants With Local Reactions Within 7 Days After Dose 1 Local reactions were recorded using an electronic diary (e-diary) by participant's legally acceptable representative (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 centimeter (cm). Redness and swelling were graded as mild (greater than [>] 0.0 to 2.0 cm), moderate (>2.0 to 7.0 cm) and severe (>7 cm).
