Study Arms:
- Nimenrix 3+1 Group (Type: EXPERIMENTAL): Subjects, male and female, received 4 doses of Nimenrix™ vaccine (3 doses at 2, 4 and 6 months of age followed by a booster dose at 15-18 months of age) and 4 doses of Synflorix™ and Infanrix-IPV/Hiberix™ vaccines (at 2, 4, 6 and 15-18 months of age). All vaccines were administered intramuscularly (IM) in the anterolateral region of the thigh.
- Nimenrix 1+1 Group (Type: EXPERIMENTAL): Subjects, male and female, received 2 doses of Nimenrix™ vaccine (1 dose at 6 months of age followed by a booster dose at 15-18 months of age) and 4 doses of Synflorix™ and Infanrix-IPV/Hiberix™ vaccines (at 2, 4, 6 and 15-18 months of age). All vaccines were administered intramuscularly (IM) in the anterolateral region of the thigh.
- Nimenrix Control Group (Type: EXPERIMENTAL): Subjects, male and female, received 1 dose of Nimenrix™ at 15-18 months of age and 4 doses of Synflorix™ and Infanrix-IPV/Hiberix™ vaccines (at 2, 4, 6 and 15-18 months of age). All vaccines were administered intramuscularly (IM) in the anterolateral region of the thigh.
