What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Geometric Mean Fold Increase in HI Antibody Titer	Geometric mean fold increase in HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination, as compared with Baseline.	Change from Baseline HI Antibody Titer at 21 days
Seroconversion Rate of Hemagglutination Inhibition (HI) Antibody Titer	Seroconversion rate was measured by hemagglutination inhibition (HI) antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination. Seroconversion rate was defined as the percentage of participants achieving a minimal 4-fold increase from the Baseline HI antibody titer in participants with a Baseline titer ≥10, or achieving an HI antibody titer of ≥40 in participants with a Baseline titer <10.	Change from Baseline HI Antibody Titer at 21 days
Seroprotection Rate of HI Antibody Titer	Seroprotection rate, defined as the percentage of participants with HI antibody titer of ≥40, was measured by HI antibody titer for each of the three strains (A/H1N1 strain, A/H3N2 strain, B strain), 21 days after vaccination. Day 1 data is reported for reference.	Change from Baseline HI Antibody Titer at 21 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With Solicited Local and Systemic Adverse Events (AEs)	Participants recorded solicited injection site and systemic adverse events in a Subject Diary. Solicited Locals AEs were: Injection Site Pain, Injection Site Redness, Injection Site Swelling, Injection Site Induration and Injection Site Ecchymosis. Solicited Systemic AEs were: Pyrexia, Malaise, Chills, Fatigue, Headache, Sweaty, Myalgia, Arthralgia, Nausea and Vomiting.	21 Days
Percentage of Participants Reporting One or More Treatment-emergent Adverse Events (TEAE)	Adverse events are defined as unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product, regardless of relationship to the medicinal product. TEAE is defined as an adverse event with an onset that occurs after receiving study drug.	21 Days
Percentage of Participants With Abnormal Safety Laboratory Tests at Least Once Post Dose Reported as AEs	The percentage of participants with any abnormal standard safety laboratory values (Chemistry, Hematology and Urinalysis) collected throughout the study reported as AEs.	21 Days
Serious adverse events (SAEs), including abnormal laboratory findings	Serious adverse events (SAEs) are 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.	21 Days
