  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.

  Normalization was performed for unit of measure "index value" as Index Value of 1.00 = 10 mIU/mL.
• Geometric Mean Antibody Concentration of Rubella in 13vPnC Group Relative to 7vPnC Group After the Toddler Dose [ Time Frame: one month after the toddler dose ] [ Designated as safety issue: No ]
