Brief Summary

Since influenza vaccines are administered every year because of the frequent change in their antigenic composition, the safety and immunogenicity profile of GSK Biologicals' influenza vaccine GSK576389A will be re-evaluated after repeated vaccine administration. In this study, the subjects previously enrolled in study 107973 will receive a dose with the 2007-2008 season's formulations of Fluarix or GSK576389A. Only subjects who were previously enrolled in study 107973 (NCT00386113) are eligible for participation in this study.

Outcome Measures

Primary Outcomes (7)

• Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms

  Solicited local symptoms assessed include ecchymosis, pain, redness and swelling. Any: any symptom regardless of intensity grade. Grade 3 pain: considerable pain at rest, which prevented normal everyday activities. Grade 3 ecchymosis, redness and swelling: more than 100 millimeter.

  During a 7-day follow-up period after vaccination

• Duration of Solicited Local Symptoms

  Duration was expressed as median number of days any symptom persisted. Solicited local symptoms assessed include ecchymosis, pain, redness and swelling. Any: occurrence of any local symptom regardless of their intensity grade.

  During a 7-day follow-up period after vaccination

• Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms

  Solicited general symptoms assessed include arthralgia, fatigue, headache, myalgia, nausea, shivering and fever. Any: any symptom regardless of intensity grade; any fever: oral temperature greater than or equal to 38 degrees Celsius (°C). Grade 3: symptoms that prevented normal activity ; Grade 3 fever: oral temperature greater than 39°C. Related: symptom assessed by the investigator as causally related to the study vaccination.

  During a 7-day follow-up period after vaccination

• Duration of Solicited General Symptoms

  Duration was expressed as median number of days any symptom persisted. Solicited general symptoms assessed include arthralgia, fatigue, headache, myalgia, nausea, shivering and fever. Any: occurrence of any general symptom regardless of their intensity grade or relationship to vaccination.

  During a 7-day follow-up period after vaccination

• Number of Subjects Reporting Any, Grade 3 and Related Unsolicited Adverse Events (AEs)

  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: occurrence of any unsolicited AE regardless of their intensity grade or relationship to vaccination. Grade 3: unsolicited AE that prevented normal everyday activities. Related: unsolicited AE assessed by the investigator as causally related to the study vaccination.

  During a 21-day follow-up period after vaccination

• Number of Subjects Reporting Any, Grade 3 and Related Medically Significant Conditions (MSCs)

  Medically Significant Conditions (MSCs) included all unsolicited adverse events that resulted in a medically attended visit. Any: occurrence of any MSC regardless of their intensity grade or relationship to vaccination. Grade 3: MSC that prevented normal everyday activities. Related: MSC assessed by the investigator as causally related to the study vaccination.

  During a 21-day follow-up period after vaccination

• Number of Subjects Reporting Any and Related Serious Adverse Events (SAEs)

  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. Any: occurrence of any SAE regardless of their relationship to vaccination. Related: SAE assessed by the investigator as causally related to the study vaccination.

  Throughout the entire study (up to Day 21)

Secondary Outcomes (7)

• Serum Haemagglutination Inhibition (HI) Antibody Titers Against Each of the Three Vaccine Strains

  At Days 0 and 21

• Number of Subjects Seropositive for HI Antibodies Against Each of the Three Vaccine Strains

  At Days 0 and 21

• Number of Subjects Seroconverted for HI Antibodies Against Each of the Three Vaccine Strains

  At Day 21

• Seroconversion Factors (SCFs) for HI Antibodies Against Each of the Three Vaccine Strains

  At Day 21

• Number of Subjects Seroprotected for HI Antibodies Against Each of the Three Vaccine Strains

  At Days 0 and 21
