Outcome Measures

Primary Outcomes (6)

  • Humoral immune response in terms of vaccine-homologous hemagglutination inhibition (HI) antibody titers

    At Day 42.

  • Occurrence of each solicited local symptom

    During a 7-day follow-up period (i.e., day of vaccination and 6 subsequent days) after each vaccination.

  • Occurrence of each solicited general symptom

    During a 7-day follow-up period (i.e., day of vaccination and 6 subsequent days) after each vaccination.

  • Occurrence of clinical safety laboratory abnormalities reported for samples

    At the Day 0, 7, 21, 28 and 42 visits.

    GMTs and Seropositivity rates at Days 0, 21, 42 and Months 6 and 12. SCR and MGI at Days 21, 42 (Placebo group only) and Months 6 and 12. SPR at Days 0, 21, 42 (Placebo group only) and Months 6 and 12.

  • Humoral immune response in terms of vaccine-homologous (H7N9) neutralizing (MN) antibody titres.

    GMTs and Seropositivity rates at the Days 0, 21, 42 and Month 6 visits. VRR at Days 21, 42 and Month 6 visits.

  • Humoral immune response in terms of vaccine-homologous (H7N9) HI antibody titers by age stratum.

    GMTs, Seropositivity rates and SPR at Days 0, 21, 42 and Months 6 and 12. SCR and MGI at Days 21, 42 and Months 6 and 12.

Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Male or female adults who are 18 to 60years of age (inclusive) at the time of first study vaccination.
  • Written informed consent obtained from subject.
  • Subjects who the investigator believes can and will comply with the requirements of the protocol.
  • Healthy subjects as established by medical history and physical examination.
  • Access to a consistent means of telephone contact.
  • For subjects who undergo a screening visit: Results of screening safety laboratory tests that figure in eligibility assessment must be within reference ranges before dosing.
  • Female subjects of non-childbearing potential may be enrolled in the study.
  • Female subjects of childbearing potential may be enrolled in the study, if they
  • have practiced adequate contraception for 30 days prior to vaccination, and
  • have a negative pregnancy test on the day of vaccination, and agree to continue to practice adequate contraception until 2 months after the last dose administered.

You may not qualify if:

  • Presence or evidence of neurological or psychiatric diagnoses which, although stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
  • Presence or evidence of substance abuse.
  • Diagnosed with cancer, or treatment for cancer within three years.
  • Diagnosed with excessive daytime sleepiness, or narcolepsy; or history of narcolepsy in a subject's parent, sibling or child.
  • Presence of a temperature ≥ 38.0ºC (≥100.4ºF), or acute symptoms greater than "mild" severity on the scheduled date of first vaccination.
  • Any confirmed or suspected immunosuppressive or immunodeficient condition including history of human immunodeficiency virus (HIV) infection.
  • Receipt of systemic glucocorticoids within 30 days prior to the first dose of study vaccine/placebo, or any other cytotoxic, immunosuppressive or immune-modifying drugs within 6 months of first study vaccine/ placebo dose.
  • Any significant disorder of coagulation or treatment with warfarin derivatives or heparin.
  • An acute evolving neurological disorder or Guillain Barré Syndrome within 42 days of receipt of prior seasonal or pandemic influenza vaccine.
  • Administration of an inactive vaccine within 14 days or of a live attenuated vaccine within 30 days before the first dose of study vaccine/placebo.
  • Planned administration of any vaccine other than the study vaccine/placebo before blood sampling at the Day 42 visit.
  • Previous administration of any H7 vaccine or physician-confirmed H7 disease.
  • Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine/placebo, or planned use during the study period.
  • Receipt of any immunoglobulins and/or any blood products within 90 days before the first dose of study vaccine/placebo, or planned administration of any of these products during the study period.
  • Any known or suspected allergy to any constituent of influenza vaccines or component used in the manufacturing process of the study vaccine including a history of anaphylactic-type reaction to consumption of eggs; or a history of severe adverse reaction to a previous influenza vaccine.
