A Study of High-Dose Trivalent Inactivated Influenza Vaccine in Adults 50 to 64 Years of Age
Safety and Immunogenicity of High-Dose Trivalent Inactivated Influenza Vaccine in Adults 50 to 64 Years of Age
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

Geometric Mean Titers (GMTs) of Vaccine Antibodies Before and After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine.
時間枠:Day 0 and Day 28 post-vaccination
|
Serum antibody titers to vaccine antigens were assessed by means of the hemagglutination inhibition (HAI) assay method.

Geometric Mean of Individual Titer Ratios (GMTRs) of Vaccine Antibodies Before and After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine
時間枠:Day 0 and Day 28 Post-vaccination

Percentage of Participants With Seroconversion After Vaccination With Either Fluzone® High-Dose or Fluzone® Vaccine
時間枠:Day 0 and Day 28 post-vaccination
|
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
時間枠:Day 0 and Day 28 post vaccination

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.
