Study Arms:
- Influenza A (H5N1) adjuvanted 6-<36M Group (Type: EXPERIMENTAL): Subjects aged at enrolment between 3 and 36 months, 36 months excluded, received 2 doses of Influenza A (H5N1) Virus monovalent vaccine (GSK1557484A vaccine or GSK Biologicals' monovalent A/Indonesia/5/2005 (H5N1) vaccine adjuvanted) at Days 0 and 21. Influenza A (H5N1) Virus monovalent vaccine was administered intramuscularly. For children aged up to 12 months, 12 months excluded (\< 12 months), Dose 1 was administered in the left anterolateral thigh and Dose 2 in the right anterolateral thigh. For children older than (\>=) 12 months, Dose 1 was administered in the deltoid region of the non-dominant arm (or left arm if dominance was not yet identified) and Dose 2 in the deltoid region of the dominant arm (or right arm).
- Influenza A (H5N1) Virus monovalent vaccine 3-<9Y Group (Type: EXPERIMENTAL): Subjects aged at enrolment between 3 and 9 years, 9 years excluded, received 2 doses of Influenza A (H5N1) Virus monovalent vaccine (GSK1557484A vaccine or GSK Biologicals' monovalent A/Indonesia/5/2005 (H5N1) vaccine adjuvanted) at Days 0 and 21. Influenza A (H5N1) Virus monovalent vaccine was administered intramuscularly, Dose 1 in the deltoid region of the non-dominant arm (or left arm if dominance was not yet identified) and Dose 2 in the deltoid region of the dominant arm (or right arm).
- Influenza A (H5N1) Virus monovalent vaccine 9-<18Y Group (Type: EXPERIMENTAL): Subjects aged at enrolment between 9 and 18 years, 18 years excluded, received 2 doses of Influenza A (H5N1) Virus monovalent vaccine (GSK1557484A vaccine or GSK Biologicals' monovalent A/Indonesia/5/2005 (H5N1) vaccine adjuvanted) at Days 0 and 21. Influenza A (H5N1) Virus monovalent vaccine was administered intramuscularly, Dose 1 in the deltoid region of the non-dominant arm (or left arm if dominance was not yet identified) and Dose 2 in the deltoid region of the dominant arm (or right arm).
- Placebo 6-<36M Group (Type: PLACEBO_COMPARATOR): Subjects aged at enrolment between 3 and 36 months, 36 months excluded, received 2 doses of saline placebo at Days 0 and 21. The saline placebo was administered intramuscularly. For children aged up to 12 months, 12 months excluded (\< 12 months), Dose 1 was administered in the left anterolateral thigh and Dose 2 in the right anterolateral thigh. For children older than (\>=) 12 months, Dose 1 was administered in the deltoid region of the non-dominant arm (or left arm if dominance was not yet identified) and Dose 2 in the deltoid region of the dominant arm (or right arm).
- Placebo 3-<9Y Group (Type: PLACEBO_COMPARATOR): Subjects aged at enrolment between 3 and 9 years, 9 years excluded, received 2 doses of saline placebo at Days 0 and 21. The saline placebo was administered intramuscularly, Dose 1 in the deltoid region of the non-dominant arm (or left arm if dominance was not yet identified) and Dose 2 in the deltoid region of the dominant arm (or right arm).
- Placebo 9-<18Y Group (Type: PLACEBO_COMPARATOR): Subjects aged at enrolment between 9 and 18 years, 18 years excluded, received 2 doses of saline placebo at Days 0 and 21. The saline placebo was administered intramuscularly, Dose 1 in the deltoid region of the non-dominant arm (or left arm if dominance was not yet identified) and Dose 2 in the deltoid region of the dominant arm (or right arm).
- Placebo/Influenza A (H5N1) adjuvanted Group (Type: EXPERIMENTAL): Subjects in this group were those who were administered the saline placebo solution in the Blinded Phase of the study (either in the Placebo 6-\<36M, Placebo 3-\<9Y or Placebo 9-\<18Y Group). These were subjects aged at enrolment between 6 months and 18 years, 18 years excluded, who had received 2 doses of saline placebo at Days 0 and 21 in the Blinded Phase of the study, as per described in the descriptions of the Placebo 6-\<36M, Placebo 3-\<9Y and Placebo 9-\<18Y groups. After consenting to participating to the Unblinded Phase of the study, these subjects received in addition 2 doses of Influenza A (H5N1) Virus monovalent vaccine at Days 385 (Day U0) and Day 385 + 21 days (Day U21). Influenza A (H5N1) Virus monovalent vaccine was administered intramuscularly. Dose 1 of was administered in the deltoid region of the non-dominant arm and Dose 2 in the deltoid region of the dominant arm.
