Geometric mean fold rises (GMFRs) for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from 1 month post-dose 2 to 1 month post-dose 3 were computed using the logarithmically transformed assay results. Confidence interval (CI) for the GMFRs were back transformations of a CI based on the Student t distribution for the logarithmically transformed assay results.

Evaluable immunogenicity population: eligible participants who were >=18 years of age on the day of first vaccination, received at least 2 doses of 13vPnC in the sequence assigned, had valid and determinate assay results, and had no major protocol violations. N (number of participants analyzed)=participants who were evaluable for this measure.

Specific local reactions were prompted for each day, and reported using an electronic diary. Redness and Swelling scaled as Any (redness present or swelling present); Mild (2.5 to 5.0 centimeters [cm]); Moderate (5.5 to 10.0 cm); Severe (greater than [>] 10 cm). Pain scaled as Any (pain present); Mild (awareness of pain; easily tolerated); Moderate (discomfort enough to cause interference with usual activity); Severe (incapacitating).

Safety population:participants who received at least 1 dose of study vaccine. 'N'(number of participants analyzed)=participants whose response was "Yes" for any day or "No" for all days. 'n' = participants whose response was "Yes" for any day or "No" for all days for specified local reaction. Participants may be represented in more than 1 category.
