Number of Subjects Reporting Fever Grade 2 or Higher
Fever grade greater than or equal to 2 i.e. ≥ 2 was defined as axillary temperature \>38 degree centigrade (°C).
Time frame: Within 7 days following any vaccination with New generation influenza vaccine GSK2186877A
Haemagglutination Inhibition (HI) Antibody Titers
Antibody titers were expressed as Geometric mean titers (GMTs). The vaccine strains included Flu A/CAL/7/09 H1N1, Flu A/Uru/716/07 H3N2 and FluB/Bri/60/08 Victoria antigens.
Time frame: At Day 0 and Day 42
The Number of Subjects Seropositive to HI Antibodies
A seropositive subject was defined as a subject with antibody titer greater than or equal to 1:10. The vaccine strains included Flu A/CAL/7/09 H1N1, Flu A/Uru/716/07 H3N2 and FluB/Bri/60/08 Victoria antigens.
Time frame: At Day 0 and Day 42
The Number of Subjects Seroprotected to HI Antibodies
A seroprotected subject was defined as a subject with a serum HI titre greater than or equal to 1:40 that usually is accepted as indicating protection. The vaccine strains included Flu A/CAL/7/09 H1N1, Flu A/Uru/716/07 H3N2 and FluB/Bri/60/08 Victoria antigens.
Time frame: At Day 0 and Day 42
The Number of Subjects Seroconverted to HI Antibodies
A seroconverted subject was defined as a subject who had either a pre-vaccination titer below 1:10 and a post-vaccination titer greater than or equal to 1:40 or a pre-vaccination titer greater than or equal to 1:10 and at least a 4-fold increase in post-vaccination titer. The vaccine strains included Flu A/CAL/7/09 H1N1, Flu A/Uru/716/07 H3N2 and FluB/Bri/60/08 Victoria antigens.
Time frame: Day 42

HI Antibody Geometric Mean Fold Rise (GMFR)
GMFR was defined as the fold increase in serum HI GMTs post-vaccination compared to pre-vaccination. The vaccine strains included Flu A/CAL/7/09 H1N1, Flu A/Uru/716/07 H3N2 and FluB/Bri/60/08 Victoria antigens.
Time frame: Day 42
Number of Subjects Reporting Any and Grade 3 Solicited Local Adverse Events (AEs)
Grade 3 redness and swelling was \> 50 millimeter (mm) and grade 3 pain was subjects crying when limb was moved/spontaneously painful. Any was occurrence of any local symptom regardless of their intensity grade.
Time frame: Within 7 days following any vaccination with New generation influenza vaccine GSK2186877A
Duration of Solicited Local AEs
Duration was defined as number of days with any grade of local symptoms following each dose of New generation influenza vaccine GSK2186877A. Dose 1 application of vaccine involved Influenza vaccine GSK2186877A formulation 1 Group and Influenza vaccine GSK2186877A formulation 2 Group while Dose 2 involved only Influenza vaccine GSK2186877A formulation 1 Group.
Time frame: Within 7 days following any vaccination with New generation influenza vaccine GSK2186877A
Number of Subjects Reporting Any, Grade 3 and Related Solicited General AEs
Any temperature was defined as axillary temperature ≥37.5°C, grade 3 temperature was axillary temperature \>39.0°C. For other symptoms, any was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination. Grade 3 drowsiness was defined as general symptom that prevented normal activity, grade 3 irritability was crying that cannot be comforted/prevented normal activity, grade 3 loss of appetite was not eating at all and grade 3 vomiting was defined as ≥3 episode of vomiting/day. Related was symptom assessed by the investigator as causally related to vaccination.
Time frame: Within 7 days following any vaccination with New generation influenza vaccine GSK2186877A
Duration of Solicited General AEs
Duration was defined as number of days with any grade of local symptoms following each dose of New generation influenza vaccine GSK2186877A. Dose 1 application of vaccine involved subjects in Influenza vaccine GSK2186877A formulation 1 Group and Influenza vaccine GSK2186877A formulation 2 Group while Dose 2 application of vaccine involved only subjects in the Influenza vaccine GSK2186877A formulation 1 Group.
Time frame: Within 7 days following any vaccination with New generation influenza vaccine GSK2186877A
Number of Subjects Reporting Any, Grade 3 and Related Unsolicited 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 was defined as occurrence of any unsolicited symptom regardless of intensity grade or relation to vaccination. Grade 3 was event that prevented normal activities and Related was defined as unsolicited AE assessed by the investigator to be causally related to the study vaccination.
Time frame: Within 21 days after any vaccination with New generation influenza vaccine GSK2186877A
Number of Subjects Reporting Any, Grade 3 and Related AEs With a Medically Attended Visit (MAEs)
For each solicited and unsolicited AE the subject experienced, the subject was asked if they had received medical attention defined as hospitalization, an emergency room visit or a visit to or from medical personnel (medical doctor) for any reason. Any was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination, grade 3 was defined as symptom that prevented normal activity and related was symptom assessed by the investigator as causally related to the study vaccination.
Time frame: Day 0 up to Month 7
Number of Subjects Reporting Any Potential Immune-Mediated-Diseases (pIMDs)
pIMDs are a subset of AEs that include both clearly autoimmune diseases and also other inflammatory and/or neurologic disorders which may or may not have an autoimmune etiology.
Time frame: Day 0 up to Month 7
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 was defined as occurrence of any symptom regardless of intensity grade or relation to vaccination and related was event assessed by the investigator as causally related to the study vaccination.
