Study Arms:
- 10Pn Group (Type: EXPERIMENTAL): Healthy male or female subjects, between 90 and 118 days of age who received 3 doses of Synflorix (10Pn) vaccine, administered intramuscularly on alternating (left/right) sides of the anterolateral thigh and DPT KAKETSUKEN Syringe (DTPa) vaccine administered subcutaneously on alternating (left/right) sides of the distal one third of the upper arm. Both vaccines were administered at 3, 4, and 5 months of age, followed by a booster dose at 17-19 months of age.
- DTPa Group (Type: ACTIVE_COMPARATOR): Healthy male or female subjects, between 90 and 118 days of age who received 3 doses of the DPT KAKETSUKEN Syringe (DTPa) vaccine, administered subcutaneously on alternating (left/right) sides of the distal one third of the upper arm at 3, 4, and 5 months of age, followed by a booster dose at 17-19 months of age.
