Outcome Measures

Primary Outcomes (1)

  • Titers for Serum H5N1 Haemagglutination-inhibition (HI) Antibodies

    Titers are presented as geometric mean titers (GMTs). The reference seropositivity cut-off value was equal to or above (≥) 1:10. The flu strain assessed was A/Indonesia/05/2005.

    At Day 42

Secondary Outcomes (16)

  • Titers for Serum H5N1 HI Antibodies

    At Day 0 and Day 180

  • Number of Subjects With H5N1 HI Antibody Concentrations Above the Cut-off Value

    At Days 0, 42 and 180

  • Number of Seroconverted Subjects Against Two Strains of Influenza Disease

    At Day 42 and Day 180

  • Seroconversion Factor (SCF) for H5N1 HI Antibodies

    At Day 42 and Day 180

  • Number of Seroprotected Subjects for H5N1 HI Antibodies

    At Days 0, 42 and 180

  • +11 more secondary outcomes

1562902A NP GROUP

EXPERIMENTAL

Healthy male or female adults, between and including 18 to 60 years of age, who received two doses of the new-processed (NP) 1562902A vaccine, administered intramuscularly in the deltoid region of the non-dominant arm, at Days 0 and 21.

EXPERIMENTAL

Healthy male or female adults, between and including 18 to 60 years of age, who received two doses of the comparative-processed (CP) 1562902A vaccine, administered intramuscularly in the deltoid region of the non-dominant arm, at Days 0 and 21.

Eligibility Criteria

Age18 Years - 59 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects who the investigator believes that they can and will comply with the requirements of the protocol should be enrolled in the study.
  • A male or female aged 18 to 60 years at the time of the first vaccination.
  • Written informed consent obtained from the subject.
  • Good general health as established by medical history and clinical examination before entering into the study.
  • Access to a consistent means of telephone contact, which may be either in the home or at the workplace, land line or mobile, but NOT a pay phone or other multiple-user device
  • Comprehension of the study requirements, ability to comprehend and comply with procedures for collection of short- and long-term safety data, expressed availability for the required study period, and ability and willingness to attend scheduled visits.
  • If the subject is female, she must be of non-childbearing potential, or if she is of childbearing potential, she must practice adequate contraception for 30 days prior to vaccination, have a negative pregnancy test and continue such precautions for 2 months after completion of the vaccination series.

You may not qualify if:

  • Evidence of substance abuse or of neurological or psychiatric diagnoses which, even if clinically stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
  • Diagnosed with cancer, or treatment for cancer, within 3 years.
  • An oral temperature ≥ 37.8 º C 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 (prednisone ≥ 5 mg/kg/day for more than 14 consecutive days) within 1 month of study enrolment, or any other cytotoxic or immunosuppressive drug within 6 months of study enrolment.
  • Any significant disorder of coagulation or treatment with Coumarin derivatives or Heparin.
  • Administration of any vaccines within 30 days before study enrolment.
  • Previous administration of any H5N1 vaccine.
  • Previous administration of vaccines with adjuvants similar to those used in the investigational vaccine.
  • Receipt of any immunoglobulins and/or any blood products within 3 months of study enrolment or planned administration of any of these products during the study period.
  • Any known or suspected allergy to any constituent of influenza vaccines (including egg proteins or mercurial preservatives); a history of anaphylactic-type reaction to consumption of eggs; or a history of severe adverse reaction to a previous influenza vaccine.
  • Known pregnancy or a positive urine beta-human chorionic gonadotropin (β-hCG) test result prior to either vaccination.
  • Lactating women.
  • Women of child bearing potential who lack a history of reliable contraceptive practices. The provision of this history does NOT replace the requirement to perform, and obtain negative results in pregnancy urine tests prior to treatments.
  • Known use of an analgesic or antipyretic medication within 12 hours prior to first treatment.
