NCT01258595

Brief Summary

The aim of the study is to generate data on key parameters associated with assessment of influenza vaccines in individuals 50-64 years of age Primary Objective:

  • To describe the immunogenicity of High-Dose Trivalent Inactivated Influenza Vaccine (TIV) compared to TIV.
  • To describe the safety profile of High-Dose Trivalent Inactivated Influenza Vaccine, as assessed by solicited adverse reactions collected for 7 days post-vaccination, and unsolicited adverse events (including Serious Adverse Events and Adverse Events of Special Interests) collected between Visit 1 and Visit 2

Outcome Measures

Primary Outcomes (4)

  • Geometric Mean Titers (GMTs) of Vaccine Antibodies Before and After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine.

    Serum antibody titers to vaccine antigens were assessed by means of the hemagglutination inhibition (HAI) assay method.

    Day 0 and Day 28 post-vaccination

  • Geometric Mean of Individual Titer Ratios (GMTRs) of Vaccine Antibodies Before and After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine

    Serum antibody titers to vaccine antigens were assessed by means of the hemagglutination inhibition (HAI) assay method.

    Day 0 and Day 28 Post-vaccination

  • Percentage of Participants With Seroconversion After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine

    Seroconversion: For participants with a Day 0 (pre-vaccination) titer \< 10 (1/dilution \[1/dil\]) a titer ≥ 40 (1/dil), and for participants with a Day 0 titer ≥ 10 (1/dil) a ≥ 4 fold increase of titer on Day 28. Serum antibody titers were assessed by means of the hemagglutination inhibition (HAI) assay method.

    Day 0 and Day 28 post-vaccination

  • Percentage of Participants With Seroprotection Before and After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine

    Seroprotection was defined as a titer ≥ 40 (1/dilution \[1/dil\]). Serum antibody titers were assessed by means of the hemagglutination inhibition (HAI) assay method.

    Day 0 and Day 28 post vaccination

Secondary Outcomes (1)

  • Number of Participants Reporting Solicited Injection Site or Systemic Reactions After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine

    Day 0 through Day 7 post-vaccination
