Clinical Trial Summary

The present study is designed to confirm the safety and immunogenicity of trivalent, surface antigen, inactivated influenza vaccine in 2 age cohorts: 18 to ≤60 years and ≥61 years and the antibody response to each influenza vaccine antigen, as measured by Single Radial Hemolysis (SRH) or Hemagglutination Inhibition (HI) at approximately 21 days post immunization.

The vaccine composition will be based on the World Health Organization (WHO) recommended influenza strains for the 2013/2014 Northern Hemisphere vaccine.

The results of this study are intended to support the use of this vaccine in future influenza seasons if the recommended vaccine composition remains the same, in compliance with the requirements of the current European Union (EU) recommendations for clinical trials related to yearly licensing of influenza vaccines.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Subjects With Single Radial Hemolysis (SRH) Areas =25mm2, Against Each of Three Vaccine Strains After Receiving One Dose of TIVf	Immunogenicity was assessed in terms of percentages of subjects in both age groups with SRH areas =25mm2 against each of the three vaccine strains, three weeks after receiving one dose of TIVf.; The related European (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving post vaccination SRH areas = 25mm2 is >70% for adults aged 18 to =60 years and >60% for subjects aged =61 years.	Day 1 (baseline) and Day 22 (postvaccination)	No
Primary	Percentages of Subjects With Seroconversion or Significant Increase in SRH Area, Against Each of Three Vaccine Strains After Receiving One Dose of TIVf	Immunogenicity was assessed in terms of percentages of subjects in both age groups achieving seroconversion or significant increase by SRH area against each of the three vaccine strains ,three weeks after receiving one dose of TIVf.; Seroconversion is defined as percentage of subjects with a pre vaccination SRH area =4mm2 achieving a post vaccination SRH area =25 mm2. Significant increase is defined as percentage of subjects with a pre vaccination SRH area >4mm2 achieving at least 50% increase in post vaccination SRH area.; The related European (CHMP) criterion for the assessment of immunogenicity is met if the percentage of subjects achieving post vaccination SRH areas = 25mm2 is >40% for adults aged 18 to =60 years and >30% for subjects aged =61 years.	Day 22 (postvaccination) /Day 1 (Baseline)	No
Primary	Geometric Mean Ratio (GMR) of Post Vaccination Versus Pre Vaccination Geometric Mean Areas (GMAs), After One Dose of TIVf	The antibody responses were evaluated in terms of GMRs of post vaccination GMAs to pre vaccination GMAs against each of the three vaccine strains, three weeks after receiving one dose of TIVf.; The related European Committee for Human Medicinal Products (CHMP) criterion for the assessment of immunogenicity is met if the GMR day 22/day 1 is >2.5 for adults aged 18 to =60 years and > 2.0 for subjects aged =61 years.

Primary	Geometric Mean Ratio of Post Vaccination Versus Pre Vaccination HI Antibody Titers, Against Each of Three Vaccine Strains After Receiving One Dose of TIVf	The antibody responses following one dose of TIVf were evaluated in terms of GMRs of post vaccination against pre vaccination geometric mean HI titers against each of the three vaccine strains, three weeks after receiving one dose of TIVf.; The related European (CHMP) criterion for the assessment of immunogenicity is met if the GMR day 22/day 1 is >2.5 for adults aged 18 to =60 years and > 2.0 for subjects aged =61 years.
