- GSK1562902A M12 Group (Type: EXPERIMENTAL): Healthy male or female adults, primed with 2 doses of adjuvanted investigational H5N1 vaccine (A/Vietnam/1194/04 strain) in study 109630 (NCT00449670) receiving one dose of Pandemic influenza candidate vaccine (GSK1562902A) in this booster study, at 12 Months (M12) after the primary vaccination, administrated intramuscularly (IM) in the deltoid region of the non-dominant arm.
- GSK1562902A M36 Group (Type: EXPERIMENTAL): Healthy male or female adults, primed with 2 doses of adjuvanted investigational H5N1 vaccine (A/Vietnam/1194/04 strain) in study 109630 (NCT00449670) receiving one dose of Pandemic influenza candidate vaccine (GSK1562902A) in this booster study, at 36 Months (M36) after the primary vaccination, administrated intramuscularly (IM) in the deltoid region of the non-dominant arm.
