About this trial

This is an interventional prevention trial for Influenza focused on measuring Influenza, Orthomyxoviruses, Split-virion inactivated influenza vaccine, cell-based vaccine, Adults

Eligibility Criteria

18 Years - 49 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria :

  • Healthy male or female subject, aged ≥ 18 to < 50 years on the day of inclusion
  • Informed consent form signed
  • Able to attend all scheduled visits and to comply with all trial procedures
  • For a woman of childbearing potential: a negative urine pregnancy test and documented use of an effective method of contraception or abstinence for at least four weeks pre vaccination and up until three weeks post-vaccination

Exclusion Criteria :

  • Subject currently breast-feeding.
  • Participation in another clinical trial investigating a vaccine, drug, medical device, or medical procedure in the 4 weeks preceding the trial vaccination.
  • Planned participation in another clinical trial during the present trial period.
  • Prior participation in the Phase I trial of FLU INTERPAN (PER.C6) vaccine (study GCE01).
  • Congenital or history of acquired immunodeficiency, or immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months.
  • Systemic corticosteroid therapy as except the use of topical or inhalant corticosteroids
  • Systemic hypersensitivity to egg proteins, chicken proteins, or to any of the vaccine components, or history of a life-threatening reaction to the trial vaccine or a vaccine containing the same substances.
  • Chronic illness at a stage that could interfere with trial conduct or completion (chronic illness may include, but is not limited to, cardiac, renal or auto-immune disorders, or diabetes).
  • Receipt of blood or blood-derived products in the 3 months preceding vaccination.
  • Receipt of any vaccination in the 4 weeks preceding vaccination, or planned receipt of any vaccination in the 4 weeks following the trial vaccination.
  • History of influenza infection (confirmed either clinically, serologically or microbiologically) within the 6 months preceding vaccination.
  • Previous vaccination against influenza (in the 6 months preceding the trial vaccination).
  • Planned receipt of any other 2007-2008 influenza vaccine.
  • Thrombocytopenia or bleeding disorder contraindicating intramuscular (IM) vaccination.
  • Subject deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized without his/her consent.
  • History of Guillain-Barré syndrome
  • Current abuse of alcohol or drug addiction that may interfere with the subject's ability to comply with trial procedures
  • Any other condition which in the opinion of the investigator would pose a health risk to the participant or interfere with the evaluation of the vaccine.

Group 1: Standard-dose Cell-based Influenza Vaccine

Group 2: High-dose Cell-based Influenza Vaccine

Group 3: Licensed Fluzone® Influenza Vaccine

Arm Description

Participants will receive a single dose of standard-dose cell-based influenza virus vaccine.

Participants will receive a single dose of high-dose cell-based influenza virus vaccine.

Participants will receive a single dose of licensed Fluzone® influenza vaccine.

Outcomes

Primary Outcome Measures

Summary of the Pre- and Post-Vaccination Geometric Mean Titers (GMTs) for Each of the Influenza Vaccine Antigens.
Percentage of Participants With Seroprotection to Each of the Influenza Vaccine Antigen Before and Post-vaccination.
Seroprotection was defined as a titer ≥ 40 1/dil, and determined in participants with a valid serology result for the particular Flu strain, including results reported as less than lower limit of quantitation (LLOQ)
Percentage of Participants Achieving Seroconversion or Significant Increase at Day 21 Following Vaccination With Influenza Vaccine.
Seroconversion: For participants with a Day 0 pre-vaccination titer < 10 (1/dil), titer ≥ 40 (1/dil) on Day 21. Significant Increase: For participants with a Day 0 pre-vaccination titer ≥ 10 (1/dil), ≥ 4-fold increase of titer on Day 21.

Secondary Outcome Measures

Number of Participants Reporting at Least 1 Solicited Injection Site or Systemic Reaction Post-vaccination With Influenza Vaccine.
Solicited Injection Site Reactions: Pain, erythema or redness, swelling, ecchymosis, and induration. Solicited Systemic Reactions: Fever (temperature), headache, malaise, myalgia, and rigors.
