Primary Outcome Measures:
  • Number of Subjects With Any, Grade 3 and Related Solicited Local Symptoms [ Time Frame: During a 7-day (Days 0-6) follow-up period after re-vaccination ] [ Designated as safety issue: No ]
    Assessed solicited local symptoms were ecchymosis, pain, redness and swelling at injection site. Any = incidence of a particular symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal everyday activity. Grade 3 redness/swelling/ecchymosis = redness/swelling/ecchymosis spreading beyond 50 millimeters (mm) of the injection site. All solicited local symptoms assessed were considered by the investigator as related to study vaccination.

  • Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms. [ Time Frame: During a 7-day (Days 0-6) follow-up after re-vaccination ] [ Designated as safety issue: No ]
    Assessed solicited general symptoms were arthralgia, fatigue, fever [oral temperature equal to or above ≥ 37.5 degrees Celsius (°C)], headache, myalgia, nausea and shivering. Any = incidence of a particular symptom regardless of grade intensity or relationship with the study vaccination. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever > 39.0°C. Related = symptom considered by the investigator to have a causal relationship to study vaccination.

  • Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs) [ Time Frame: During a 30-day (Days 0-29) follow-up period after re-vaccination ] [ Designated as safety issue: No ]
    Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any = any unsolicited AE regardless of intensity or relationship to vaccination. Grade 3 = unsolicited AE that prevented normal activity. Related = unsolicited AE assessed by the investigator as causally related to the study vaccination.

  • Number of Subjects With Any and Related Serious Adverse Events (SAEs) [ Time Frame: During the entire study period (Days 0-30) ] [ Designated as safety issue: No ]
    Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject. Related = SAE assessed by the investigator as causally related to the study vaccination.


Secondary Outcome Measures:
  • Titers for Serum Hemagglutination Inhibition (HI) Antibodies Against 3 Strains of Influenza Disease. [ Time Frame: At Days 0 and 21 ] [ Designated as safety issue: No ]
    Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL). The seropositivity cut-off assay was 1:10.

  • Number of Seroconverted Subjects Against 3 Strains of Influenza Disease. [ Time Frame: At Day 21 ] [ Designated as safety issue: No ]
    A seroconverted subject was defined as a vaccinated subject who had either a pre-vaccination titer <1:10 and a post-vaccination titer ≥1:40 or a pre-vaccination titer ≥1:10 and at least a four-fold increase in post-vaccination titer. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL).

  • Number of Seroprotected Subjects Against 3 Strains of Influenza Disease. [ Time Frame: At Day 0 and 21 ] [ Designated as safety issue: No ]
    A seroprotected subject was defined as a vaccinated subject who had a serum HI titer ≥ 1:40. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL).

  • Seroconversion Factor for HI Antibodies Against 3 Strains of Influenza Disease. [ Time Frame: At Day 21 ] [ Designated as safety issue: No ]
    The seroconversion factor (SCF) was defined as the fold increase in serum Hemagglutination Inhibition (HI) geometric mean titers (GMTs) post vaccination compared to Day 0. The 3 influenza strains assessed were A/Solomon Islands (A/SOL), A/Wisconsin (A/WIS) and B/Malaysia (B/MAL).

Arms Assigned Interventions
Experimental: GSK1247446A Group
Subjects aged between 18 and 60 years, having previously received one dose of the AS03-adjuvanted GSK1247446A vaccine in the primary study NCT00374842, received a single dose of GSK1247446A vaccine adjuvanted with a half dose of AS03 adjuvant at Day 0 of the current follow-up study NCT00545025. The vaccine was administered intramuscularly, in the deltoid region of the non-dominant arm. Subjects in this group originated from either the GSK1247446A Formulation 1 or GSK1247446A Formulation 2 groups in study NCT00374862.
Biological: Influenza Vaccine GSK1247446A
Single dose, Intramuscular injection
Active Comparator: Fluarix Group
Subjects aged between 18 and 60 years, having previously received one dose of Fluarix™ vaccine during the primary study NCT00374842, received one dose of Fluarix™ vaccine at Day 0 of the current follow-up study NCT00545025. The vaccine was administered intramuscularly, in the deltiod region of the non-dominant arm. Subjects in this group originated from the Fluarix Group in study NCT00374862.
Biological: Fluarix™
Single dose, Intramuscular injection
