Brief summary

The present study is designed to evaluate the safety and immunogenicity of trivalent, surface antigen, inactivated influenza vaccine in 2 age cohorts: 18 to ≤60 years and ≥61 years. For the immunogenicity endpoint the antibody response to each influenza vaccine antigen will be evaluated by means of Single Radial Hemolysis (SRH) or Hemagglutination Inhibition (HI) at approximately 21 days post vaccination. The vaccine composition will be based on the WHO recommended influenza strains for the 2015 Southern Hemisphere vaccine, and the data from this study are intended to support the use of this vaccine in future influenza seasons if the recommended vaccine composition remains the same.

Primary

Percentages of Subjects With Single Radial Hemolysis (SRH) Areas ≥25mm^2, Against Each of Three Vaccine Strains After Receiving One Dose of TIV.

Immunogenicity was assessed in terms of percentages of subjects in both age groups with SRH areas ≥25mm\^2 against each of the three vaccine strains, three weeks after receiving one dose of TIV. The related European Committee for Medicinal Products for Human Use (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving post vaccination SRH areas ≥ 25mm\^2 is \>70% for adults aged 18 to ≤60 years and \>60% for subjects aged ≥61 years.

Time frame: Day 1 and Day 22 post vaccination

Population: The analysis was performed on the per-protocol population (PP).
