A Study to Evaluate Safety and Immunogenicity of Trivalent Influenza Vaccine, Formulation 2015 Southern Hemisphere, When Administered to Healthy Adult Subjects.
Condition: Human Influenza
MeSH terms: Influenza, Human
Intervention: Aggripal®
Intervention description: TIV
Phase: Phase 2
Study type: Interventional
Primary purpose: Prevention
Intervention model: Single Group Assignment
Masking: None (Open Label)
Enrollment: 126.0
Sex: All
Minimum age: 18 Years
Healthy volunteers: Accepts Healthy Volunteers

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.
