Primary | Titers for Serum Hemagglutination Inhibition (HI) Antibodies Against 3 Strains of Influenza Disease. | Titers are presented as geometric mean titers (GMTs). The 3 influenza strains assessed were A/Solomon Islands (SOLO), A/Wisconsin (WISC) and B/Malaysia (MALA). The seropositivity cut-off assay was 1:10. The results for Day 0 and Day 21 are the primary efficacy variables. | At Days 0, 21 and 180 | |
Secondary | Number of Seroconverted Subjects Against 3 Strains of Influenza Disease. | 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 (SOLO), A/Wisconsin (WISC) and B/Malaysia (MALA). | At Days 21 and 180 | |
Secondary | Seroconversion Factor for Hemagglutination Inhibition (HI) Antibodies Against 3 Strains of Influenza Disease. | The seroconversion factor (SCF) was defined as the fold increase in serum Hemagglutination Inhibition (HI) geometric mean titers (GMTs) post vaccination compared to Day 0. The 3 influenza strains assessed were A/Solomon Islands (SOLO), A/Wisconsin (WISC) and B/Malaysia (MALA). | At Days 21 and 180 | |
Secondary | Number of Seroprotected Subjects Against 3 Strains of Influenza Disease. | A seroprotected subject was defined as a vaccinated subject who had a serum HI titer = 1:40. The 3 influenza strains assessed were A/Solomon Islands (SOLO), A/Wisconsin (WISC) and B/Malaysia (MALA). | At Days 0, 21 and 180 | |
Secondary | Titers for Serum Hemagglutination Inhibition (HI) Antibodies Against 4 Strains of Influenza Disease. | Titers are presented as geometric mean titers (GMTs). The 4 influenza strains assessed were A/Wisconsin (WISC), B/Malaysia (MALA), A/Brisbane (BRIS) and B/Florida (FLOR). The seropositivity cut-off assay was 1:28. | At Days 0 and 21 | |
Secondary | Geometric Mean of Influenza-specific Cluster of Differentiation (CD) 4 T-cells. | The mean was calculated for CD4 T-cells (per million CD4 T-cells) producing at least two different cytokines (All Doubles), at least CD40L, at least INF gamma (IFN-?), at least IL2 and at least TNF alpha (TNF-a). | At Days 0, 21 and 180 | |
Secondary | Geometric Mean of Influenza-specific Cluster of Differentiation (CD) 8 T-cells. | The mean was calculated for CD8 T-cells (per million CD8 T-cells) producing at least two different cytokines (All Doubles), at least CD40L, at least INF gamma (IFN-?), at least IL2 and at least TNF alpha (TNF-a). | At Days 0, 21 and 180 | |
Secondary | Number of Subjects With Any and Grade 3 Solicited Local Symptoms. | Assessed solicited local symptoms were ecchymosis, pain, redness and swelling at injection site. Any = incidence of a particular symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal everyday activity. Grade 3 redness/swelling/ecchymosis = redness/swelling/ecchymosis spreading beyond 50 millimeters (mm) of the injection site. | During the 7-day (Days 0-6) post vaccination period | |
Secondary | Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms. | Assessed solicited general symptoms were arthralgia, fatigue, fever [oral temperature above (>) 38.0 degrees Celsius (°C)], headache, myalgia, nausea and shivering. Any = incidence of a particular symptom regardless of grade intensity or relationship with the study vaccination. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever = 39.0°C. Related = symptom considered by the investigator to have a causal relationship to study vaccination. | During the 7-day (Days 0-6) post vaccination period | |
Secondary | Number of Subjects With Any, Grade 3 and Related Medically Significant Conditions (MSCs). | MSCs were defined as conditions prompting emergency room visits or physician visits that were not related to common diseases or routine visits. Any = incidence of a particular symptom regardless of grade intensity or relationship with the study vaccination. Grade 3 = event which prevented normal activities. Related = event assessed by the investigator as causally related to the study vaccination | From Day 0 to Day 180 | |
Secondary | Number of Subjects With 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 = any unsolicited AE regardless of intensity or relationship to vaccination. Grade 3 = unsolicited AE that prevented normal activity Related = unsolicited AE assessed by the investigator as related to the vaccination. | During the 21-day (Days 0-20) post vaccination period | |
Secondary | Number of Subjects With Serious Adverse Events (SAEs). | 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. | From Day 0 to Day 180 |
