Name Time Method Percentage of Adult Participants Experiencing ≥1 Adverse Event (AE) Up to 14 days An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
Percentage of Adult Participants Discontinuing From Study Treatment Due to an Adverse Event (AE) Up to 14 days An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
Percentage of Infant Participants Experiencing ≥1 Adverse Event (AE) Up to 14 days after the 4th vaccination (approximately 12.5 to 15.5 months of age) An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. For infants, AEs were monitored for up to 14 days following each vaccination.

Estimated Fold-Rise Per-Unit Change in Serotype-specific Antibody Concentrations Following an Increase in Polysaccharide Concentrations in Infants at 1 Month Postdose 3 (PD3) Month 7 (1 month PD3) A mulitvariate regression model was used to evaluate the impact of increasing polysaccharide concentration from 1x to 2x on the natural logarithm of serotype-specific antibody concentrations 1 month PD3. Data points show the mean estimated fold-rise-per-unit change in antibody concentration following an increase from 1x to 2x in polysaccharide concentration. For each Prevnar 13®-type (PT) or non-Prevnar 13®-type (non-PT) serotypes, values \>1.0 show an increase in antibody concentration whereas values \<1.0 show a decrease in antibody concentration.
Estimated Fold-Rise Per-Unit Change on Serotype-specific Antibody Concentrations Following an Increase in Aluminum Phosphate Adjuvant (APA) Concentration 1 Month Postdose 3 (PD3) in Infants Month 7 (1 month PD3) A mulitvariate regression model was used to evaluate the impact of increasing APA concentration on the natural logarithm of serotype-specific antibody concentrations 1 month PD3. Data points show the mean estimated fold-rise-per-unit change in antibody concentration following an increase in APA. For each Prevnar 13®-type (PT) or non-Prevnar 13®-type (non-PT) serotypes, values \>1.0 show an increase in antibody concentration whereas values \<1.0 show a decrease in antibody concentration.
