Group Intervention Description GSK 1388442A Group Trivalent influenza vaccine GSK 138842A Subjects aged 18 to 49 years of age at the time of vaccination received 1 dose of GSK 1388442A vaccine at Day 0. The GSK 1388442A vaccine was administered intramuscularly in the deltoid region of the non-dominant arm. Fluarix Group Fluarix Subjects aged 18 to 49 years of age at the time of vaccination received 1 dose of Fluarix® vaccine at Day 0. The Fluarix® vaccine was administered intramuscularly in the deltoid region of the non-dominant arm.
- Primary Outcome Measures
Name Time Method Number of Subjects With Solicited Local Symptoms. During the 7-day (Days 0-6) post vaccination period Solicited local symptoms were pain, redness and swelling at the injection site. Any = occurrence of a symptom regardless of intensity.
Number of Subjects With Solicited General Symptoms. During the 7-day (Days 0-6) post vaccination period Solicited general symptoms were arthralgia, fatigue, headache, muscle aches, shivering and temperature, assessed as oral temperature above or equal (≥) 38.0 degrees Celsius (°C). Any = occurrence of a symptom regardless of intensity or relationship to vaccination.
Number of Subjects With Unsolicited Adverse Events (AEs). During the 90-day (Days 0-89) post-vaccination period Unsolicited AEs cover any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Any unsolicited AE = any unsolicited AE regardless of intensity or relationship to vaccination.
Number of Subjects With Serious Adverse Events (SAEs). During the entire study period (Days 0-182) 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. Any SAE = any SAE regardless of intensity or relationship to vaccination.
Number of Seroconverted Subjects Against 3 Strains of Influenza Disease. At Day 21 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/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)
Titers for Serum Hemagglutination Inhibition (HI) Antibodies for 3 Strains of Influenza Disease. At Day 21 Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)
Number of Seroprotected Subjects Against 3 Strains of Influenza Disease. At Day 21 A seroprotected subject was defined as a vaccinated subject with a serum HI antibody titer ≥ 1:40, a level of HI antibody that has been viewed as correlating with protection against influenza. The 3 influenza strains assessed were A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)
Number of Subjects With Medically Attended Adverse Events (MAEs). During the entire study period (Days 0-182) Medically-attended events (MAEs) refer to non-serious and serious events leading to an otherwise unscheduled visit to or from medical personnel for any reason, including emergency room visits and hospitalization. Related MAE = MAE assessed by the investigator as related to the vaccination.
Number of Subjects With New Onset of Chronic Diseases (NOCDs). During the entire study period (Days 0-182) NOCDs include conditions such as autoimmune disorders, asthma, type I diabetes, or allergies.
Geometric Mean Fold-rise (GMFR) in 3 Strains of Influenza Disease. At Day 0 and Day 21 GMFR was defined as the geometric mean of the ratio of the post-vaccination inverse HI titer to the Day 0 inverse HI titer. The 3 influenza strains assessed were A/Solomon Islands/3/2006 (H1N1), A/Wisconsin/67/2005 (H3N2) and B/Malaysia/2506/2004 (MALAY.)
