Humoral Immune Response in Terms of Haemagglutination (HA) Antibody Titers Against Each of the Three Vaccine Influenza Strains
Antibody titers were expressed as Geometric mean titers (GMTs). The vaccine strains assessed were Flu A/Christchurch/16/10 (H1N1), Flu A/Victoria/361/11 (H3N2) and Flu B/Hubei-Wujiagang/158/09 (Yamagata).
Time frame: At Day 0 and Day 21
Number of Subjects Who Were Seroprotected for Anti-HA Antibodies Against Each of the Three Vaccine Influenza Strains.
Seroprotection rate (SPR) was defined as the number of vaccinees with serum haemagglutination inhibition (HI) titer greater than or equal to (≥) 1:40.
Time frame: At Day 0 and Day 21
Number of Seroconverted Subjects for Anti-HA Antibodies Against Each of the Three Vaccine Influenza Strains.
A seroconverted subjects was defined as a vaccinee with either a pre-vaccination titer less than (\<) 1:10 and a post-vaccination titer ≥ 1:40, or a pre-vaccination titer ≥ 1:10 and at least a 4-fold increase in post-vaccination titer.
Time frame: At Day 21
Mean Geometric Increase (MGI) for Haemagglutination Inhibition (HI) Antibody Titer Against Each of the Three Vaccine Influenza Strains.
MGI was defined as the fold increase in serum HI GMT post-vaccination compared to Day 0.
Time frame: At Day 21
Number of Subjects With Seroprotection Power (SPP) for HI Antibody Titer Against Each of the Three Vaccine Influenza Strains Above the Cut-off Value.
SPP was defined as the number of vaccinees with a pre-vaccination titer \< 1:40 and a post-vaccination titer ≥ 1:40.
Time frame: At Day 21
Humoral Immune Response in Terms of Anti-HA Antibodies Against Each of the Three Vaccine Influenza Strains.

Antibody titers were expressed as Geometric mean titers (GMTs). The vaccine strains included H1N1, H3N2 and Yamagata antigens. The outcome measure was assessed by influenza vaccination status in the 2011-2012 season, in subjects aged greater than (\>) 60 years.
Time frame: At Day 0 and Day 21
Number of Subjects Who Were Seroprotected for Anti-HA Antibodies Against Each of the Three Vaccine Influenza Strains.
Seroprotection rate SPR was defined as the number of vaccinees with serum haemagglutination inhibition (HI) titer greater than or equal to (≥) 1:40. The outcome measure was assessed by the influenza vaccination status in the 2011-2012 season, in subjects aged \> 60 years.
Time frame: At Day 0 and Day 21
Number of Subjects Who Seroconverted for Anti-HA Antibodies Against Each of the Three Vaccine Influenza Strains.
SCR was defined as the number of vaccinees with either a pre-vaccination titer less than (\<) 1:10 and a post-vaccination titer ≥ 1:40, or a pre-vaccination titer ≥ 1:10 and at least 4-fold increase in post-vaccination titer. The outcome measure was assessed by influenza vaccination status in the 2011-2012 season, in subjects aged \> 60 years.
Time frame: At Day 21
Mean Geometric Increase (MGI) for Haemagglutination Inhibition (HI) Antibody Titer Against Each of the Three Vaccine Influenza Strains.
MGI was defined as the fold increase in serum HI GMT post-vaccination compared to Day 0. This outcome measure was assessed by influenza vaccination status in the 2011-2012 season, in subjects aged \> 60 years.
Time frame: At Day 21
Duration of Solicited Local Symptoms.
Duration was defined as number of days with any grade of local symptoms.
Time frame: During the 4-day follow-up period (Days 0-3) after vaccination
Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms.
Solicited local symptoms assessed were ecchymosis, induration, pain, redness and swelling. Any was defined as any solicited local symptom reported irrespective of intensity. Grade 3 pain was defined as pain that prevented normal everyday activities. Grade 3 ecchymosis, induration, redness and swelling was greater than 100 millimeters (mm) i.e. \>100mm.
Time frame: During the 4-day (Day 0-Day 3) follow-up period after vaccination
Duration of Solicited General Symptoms.
Duration was defined as number of days with any grade of general symptoms.
Time frame: During the 4-day follow-up period (Days 0-3) after vaccination
Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms.
Solicited general symptoms assessed were arthralgia, fatigue, gastrointestinal symptoms, headache, myalgia, shivering, increased sweating and fever \[axillary temperature above 37.5 degrees Celsius (°C)\]. Gastrointestinal symptoms included nausea, vomiting, diarrhea and/or abdominal pain. Any = any solicited general symptom reported irrespective of intensity and relationship to vaccination. Related = symptoms considered by the investigator to have a causal relationship to vaccination. Grade 3 symptoms = symptoms that prevented normal activity. Grade 3 fever = axillary temperature above 39.0°C
Time frame: During the 4-day follow-up period (Day 0-3) 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 was defined as occurrence of any unsolicited symptom regardless of intensity grade or relation to vaccination. Grade 3 was an event that prevented normal activities and related was defined as an unsolicited AE assessed by the investigator to be causally related to the study vaccination.
Time frame: During the 21-day follow-up period (Days 0-20) after vaccination
Number of Subjects Reporting Any and Related Serious Adverse Events (SAEs)
A serious adverse event was any untoward medical occurrence that: resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or was 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 an event assessed by the investigator as causally related to the study vaccination.
