The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of the 13-valent pneumococcal vaccine (13vPnC) compare to the 7-valent pneumococcal vaccine (7vPnC) and to compare the immune response to concomitant vaccines administered with 13vPnC and 7vPnC.

Systemic events (any fever \[Fv\] ≥ 38 degrees Celsius \[C\], decreased (decr.) appetite, irritability, increased (incr.) sleep, decreased sleep, and hives \[urticaria\], use of antipyretic medication \[med\] to treat or prevent symptoms \[sx\]) were reported using an electronic diary. Participants may be represented in more than 1 category.
Time frame: Within 7 days after each dose

Percentage of Participants Reporting Pre-specified Local Reactions
Local reactions were reported using an electronic diary. Tenderness was scaled as Any (tenderness present); Significant (\[Sig.\], present and interfered with limb movement). Redness and swelling were scaled as Any (redness or swelling present); Mild (0.5 centimeters \[cm\] to 2.0 cm); Moderate (\[Mod.\], 2.5 to 7.0 cm); Severe (\[Sev.\], \> 7.0 cm). Participants may have been represented in more than 1 category.
Time frame: Within 7 days after each dose
