Percentage of Participants With a New Acquisition of Serotype 6A' (6A + 6C) or 19A Combined 1 Month After the Infant Series to 24 Months of Age [ Time Frame: Month 7 through Month 24 ] [ Designated as safety issue: No ]
A new acquisition was defined as the detection of a serotype (here 6A' [6A + 6C] or 19A), once a participant was fully vaccinated (one month after dose 3), that had not been detected previously in the baseline samples at 2, 4, 6 months of age.
Primary comparison is culture findings in subjects receiving 13vPnC relative to those receiving 7vPnC. Primary endpoint is proportion of subjects with a new acquisition of either serotype 6A or 19A 1 month after the infant series to 24 months of age.

Percentage of Participants With Nasopharyngeal Cultures Testing Positive for 6A' (6A + 6C) or 19A Serotypes of Streptococcus Pneumoniae (S. Pneumoniae) at 7, 12, 13, 18 and 24 Months of Age [ Time Frame: Month 7, 12, 13, 18, 24 ] [ Designated as safety issue: No ]
Secondary endpoints are the proportion of cultures testing positive for serotypes 6A or 19A of s. pneumoniae as a group measured at 18 months of age and from 1 month after the infant series to 24 months of age.
