Primary outcomes

  1. Titers for Hemagglutination Inhibition (HI) Antibodies Against 4 Strains of Influenza Disease

    Time frame: At Day 0 (D 0), and at Day 21 (D 21)

    Titers are presented as geometric mean titers (GMTs). The reference cut-off value was 1:10. HI antibodies assessed were antibodies against the A/California/7/2009 (H1N1), A/Victoria/210/2009 (H3N2), B/Brisbane/60/2008 (Victoria), and B/Brisbane/3/2007 (Yamagata) flu strains. Subjects receiving the GSK2321138A vaccine were pooled for this outcome measure.

  2. Number of Seroconverted Subjects Against 4 Strains of Influenza Disease

    Time frame: At Day 21 (D 21)

    A seroconverted subject was a vaccinated subject who had either a pre-vaccination hemagglutination inhibition (HI) antibody titer < 1:10 and a post-vaccination titer above or equal (>=) 1:40, or a pre-vaccination HI antibody titer >= 1:10 and at least a 4-fold increase in post-vaccination HI antibody titer. Antibodies assessed were HI antibodies against the A/California/7/2009 (H1N1), A/Victoria/210/2009 (H3N2), B/Brisbane/60/2008 (Victoria), and B/Brisbane/3/2007 (Yamagata) flu strains. Subjects receiving the GSK2321138A vaccine were pooled for this outcome measure.

Secondary outcomes

  1. Number of Seropositive Subjects Against 4 Strains of Influenza Disease

    Time frame: At Day 0 (D 0), and at Day 21 (D 21)

    A seropositive subject was a vaccinated subject with hemagglutination inhibition (HI) antibody titer above or equal (>=) the reference cut-off value of 1:10. Antibodies assessed were HI antibodies against the A/California/7/2009 (H1N1), A/Victoria/210/2009 (H3N2), B/Brisbane/60/2008 (Victoria), and B/Brisbane/3/2007 (Yamagata) flu strains. Subjects receiving the GSK2321138A vaccine were pooled for this outcome measure.

  2. Number of Seroprotected Subjects Against 4 Strains of Influenza Disease

    Time frame: At Day 0 (D 0), and at Day 21 (D 21)

    A seroprotected subject was a vaccinated subject who had hemagglutination inhibition (HI) antibody titer above or equal (>=) 1:40. Antibodies assessed were HI antibodies against the A/California/7/2009 (H1N1), A/Victoria/210/2009 (H3N2), B/Brisbane/60/2008 (Victoria), and B/Brisbane/3/2007 (Yamagata) flu strains. Subjects receiving the GSK2321138A vaccine were pooled for this outcome measure.

  3. Increase in Hemagglutination Inhibition Antibodies Against 4 Strains of Influenza Disease

    Time frame: At Day 21 (D 21)

    Increase in hemagglutination inhibition (HI) antibodies is presented in terms of mean geometric increase (MGI), defined as the geometric mean of the within subject ratios of the post-vaccination reciprocal HI titer to the Day 0 reciprocal HI titer , expressed using "fold increase" as unit . Antibodies assessed were HI antibodies against the A/California/7/2009 (H1N1), A/Victoria/210/2009 (H3N2), B/Brisbane/60/2008 (Victoria), and B/Brisbane/3/2007 (Yamagata) flu strains. Subjects receiving the GSK2321138A vaccine were pooled for this outcome measure.

  4. Number of Subjects With Any and Grade 3 Solicited Local Symptoms.

    Time frame: Within the 7-day (Days 0-6) follow-up period after vaccination

    Assessed solicited local symptoms post vaccination were pain, redness and swelling at the injection site. Any = occurrence of a symptom regardless of intensity. Grade 3 pain = significant pain at rest/ that prevented normal every day activities. Grade 3 redness/swelling = redness/swelling spreading beyond 100 millimeters (mm) of injection site.

  5. Number of Days With Solicited Local Symptoms

    Time frame: Within the 7-day (Days 0-6) follow-up period after vaccination

    Assessed solicited local symptoms post vaccination were pain, redness and swelling at the injection site.

  6. Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms

    Time frame: Within the 7-day (Days 0-6) follow-up period after vaccination

    Assessed solicited general symptoms post vaccination were fatigue, gastrointestinal symptoms (Gastr.), headache, joint pain at other location (Joint Pain), muscle aches, shivering, and temperature [axillary temperature above or equal to (>=) 37.5 degrees Celsius (°C)]. Any = occurrence of a symptom regardless of intensity or relationship to vaccination. Grade 3 = symptom which prevented normal every day activities. Grade 3 temperature = axillary temperature > 39°C. Related = symptom assessed as causally related to study vaccination.

  7. Number of Days With Solicited General Symptoms

    Time frame: Within the 7-day (Days 0-6) follow-up period after vaccination

    Assessed solicited general symptoms post vaccination were fatigue, gastrointestinal symptoms (Gastr.), headache, joint pain at other location (Joint Pain), muscle aches, shivering, and temperature [defined as axillary temperature above or equal to (≥) 37.5 degrees Celsius (°C)].

  8. Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs)

    Time frame: Within the 21-day (Days 0-20) follow-up period after vaccination

    Unsolicited AEs cover 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 unsolicited AE = any unsolicited AE regardless of intensity or relationship to vaccination. Grade 3 unsolicited AE = unsolicited AE that prevented normal everyday activity Related unsolicited AE = unsolicited AE assessed by the investigator as related to the vaccination.

  9. Number of Subjects With Any and Related Adverse Events With Medically-attended Events (MAEs)

    Time frame: From the beginning of the study (Day 0) to study end (Day 180)

    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. If a MAE was leading to hospitalisation (or met any other serious adverse event criterion), it was reported as serious adverse event. Related MAE = MAE assessed by the investigator as related to the vaccination. Subjects receiving the GSK2321138A vaccine were pooled for this outcome measure.

  10. Number of Subjects With Any and Related Potential Immune-mediated Diseases (pIMDs)

    Time frame: From the beginning of the study (Day 0) to study end (Day 180)

    Potential immune-mediated diseases (pIMDs) are a subset of adverse events that include both clearly autoimmune diseases and also other inflammatory and/or neurologic disorders which may or may not have an autoimmune etiology. Related pIMD = pIMD assessed by the investigator as related to the vaccination. Subjects receiving the GSK2321138A vaccine were pooled for this outcome measure.

  11. Number of Subjects With Any and Related Serious Adverse Events (SAEs)

    Time frame: From the beginning of the study (Day 0) to study end (Day 180)

    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. Related SAE = SAE assessed by the investigator as related to the vaccination.
