Brief Summary

The purpose of this study is to evaluate the safety of a single intramuscular (IM) injection of the cell derived subunit trivalent nonadjuvanted influenza vaccine in adult and elderly subjects and the antibody response to each influenza vaccine antigen, as measured by hemagglutination inhibition (HI) at approximately 21 days postimmunization in adult and elderly subjects in compliance with the requirements of the current EU recommendations for clinical trials related to yearly licensing of influenza vaccines.

Outcome Measures

Primary Outcomes (3)

• Percentages of Subjects With Seroconversion or Significant Increase in HI Titer Against Each of Three Vaccine Strains After One Vaccination of TIVc

  Immunogenicity was measured as the percentage of subjects who achieved seroconversion or significant increase in hemagglutination inhibition (HI) titer, against each of three vaccine strains, three weeks after vaccination (day 22), evaluated using HI cell-derived antigen assay. As per the European (CHMP) criteria, seroconversion or significant increase in titer is defined as the percentage of subjects with a prevaccination HI titer \<10 to a postvaccination HI titer ≥40; or in subjects with a prevaccination HI titer ≥10, a ≥4-fold increase in postvaccination HI antibody titer. This criterion is met according to CHMP guideline if percentage of subjects achieving seroconversion or significant increase in HI titer is \>40% (≥18 years to ≤60 years) or 30% (≥61 years).

  Day 22

• Geometric Mean Ratio of Subjects Against Each of Three Vaccine Strains After One Vaccination of TIVc

  Geometric mean ratio (GMR) of subjects was calculated as the ratio of postvaccination to prevaccination HI geometric mean titers (GMTs), directed against each of three vaccine strains, three weeks after vaccination (day 22). The CHMP criterion was met if the geometric mean increase (GMR, day 22/day 1) in HI antibody titer is \>2.5 (≥18 years to ≤60 years) or \>2.0 (≥61 years).

  Day 22

• Percentages of Subjects Who Achieved HI Titer ≥40 Against Each of Three Vaccine Strains After One Vaccination of TIVc

  Immunogenicity was measured as the percentage of subjects achieving HI titer ≥40 against each of three vaccine strains at baseline (day 1) and three weeks after TIVc vaccination (day 22). This criterion was met according to CHMP guideline if percentage of subjects achieving HI titer ≥40 is \>70% (≥18 years to ≤60) or 60% (≥61 years).

  Day 1 and 22

Secondary Outcomes (2)

• Number of Subjects Who Reported Solicited Local and Systemic Reactions (Day 1 - Day 4 Postvaccination)

  From day 1 through day 4 postvaccination

• Number of Subjects Reporting Unsolicited Adverse Events After Receiving One Dose of TIVc.

  Day 1 to Day 22

• Acute or progressive hepatic disease;
• Acute or progressive renal disease;
• Severe neurological (es. Guillain-Barré syndrome) or psychiatric disorder;
• Severe asthma.
• Individuals with history of any anaphylactic reaction and/or serious allergic reaction following a vaccination, a proven hypersensitivity to any component of the study vaccine (e.g.Influenza viral protein).
