Study Arms:
- GSK2321138A 1 Group (Type: EXPERIMENTAL): Subjects aged 3-17 years received if primed, 1 dose of GSK2321138A at Day 0 and if unprimed, 2 doses of GSK2321138A at Day 0 and Day 28. The vaccine was administered intramuscularly into the deltoid for subjects aged 12 months or above or into the anterolateral region of the thigh for subjects below 12 month of age. The vaccine was administered in the non-dominant side of the body at Day 0 and in the opposite side at Day 28.
- Fluarix Group (Type: ACTIVE_COMPARATOR): Subjects aged 3-17 years received if primed, 1 dose of Fluarix at Day 0 and if unprimed, 2 doses of Fluarix at Day 0 and Day 28. The vaccine was administered intramuscularly into the deltoid for subjects aged 12 months or above or into the anterolateral region of the thigh for subjects below 12 month of age. The vaccine was administered in the non-dominant side of the body at Day 0 and in the opposite side at Day 28.
- GSK2604409A Group (Type: ACTIVE_COMPARATOR): Subjects aged 3-17 years received if primed, 1 dose of GSK2604409A at Day 0 and if unprimed, 2 doses of GSK2604409A at Day 0 and Day 28. The vaccine was administered intramuscularly into the deltoid for subjects aged 12 months or above or into the anterolateral region of the thigh for subjects below 12 month of age. The vaccine was administered in the non-dominant side of the body at Day 0 and in the opposite side at Day 28.
- GSK2321138A 2 Group (Type: EXPERIMENTAL): Subjects aged 6-35 months received if primed, 1 dose of GSK2321138A at Day 0 and if unprimed, 2 doses of GSK2321138A at Day 0 and Day 28. The vaccine was administered intramuscularly into the deltoid for subjects aged 12 months or above or into the anterolateral region of the thigh for subjects below 12 month of age. The vaccine was administered in the non-dominant side of the body at Day 0 and in the opposite side at Day 28.
