Arms Assigned Interventions
Experimental: Group A
Two Multimeric-001 priming administrations followed by TIV boost

Adjuvanted (Aluminum phosphate) Multimeric-001 will be injected once and followed by TIV booster immunization with the interval of 19-23 days between them.
Active Comparator: Group D
Saline will be injected once followed by TIV immunization with the interval of 19-23 days between them.
Biological: Saline and TIV
PBS (Placebo) will be injected once followed by TIV that serves as an active comparator with the interval of 19-23 days between them.

Detailed Description:

This is a Phase II multi-center, randomized, two stage, double-blind, placebo-controlled, single-dose administration study comprising 120 participants. Eligible elderly subjects will be randomized to receive one of the following administrations (as two single IM injections with an interval of 21 days between each injection Administration A (prime): Adjuvanted or non adjuvanted Multimeric-001 500 mcg - ninety (90) subjects.

Administration B (Boost): commercial seasonal trivalent vaccine for 2012 - thirty (30) subjects. A control group of thirty (30) subjects will be injected with PBS followed by TIV administration 21 days later.

  Eligibility

Ages Eligible for Study:   65 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Males and females at the age of at least 65 years old
  • Eligible to receive the standard seasonal influenza vaccine according to the MOH guidelines.
  • Subjects who provide written informed consent to participate in the study.
  • Subjects able to adhere to the visit schedule and protocol requirements and are available to complete the study.
  • Haematology, chemistry and urinalysis values with no clinical significance or do not reflect a medical condition which, according to the physician's judgment, might confound the results of the study or pose additional risk to the subject by participation in the study.
  • Male subjects must agree to use a condom during the full term of the study period (including follow up) if female partner is not using an acceptable contraceptive method.
  • Subjects who are seronegative to at least one of the strains included in the seasonal vaccine against influenza for 2011- 2012

Exclusion Criteria:

  • Known history of significant medical disorder which, in the investigator's judgment, might confound the results of the study or pose additional risk to the subject by participation in the study.
  • Subjects with known Guillain Barré Syndrome in the past.
  • Subjects who have been immunized with anti-influenza vaccine or infected by influenza virus within eight months prior to the screening visit.
  • Known hypersensitivity associated with previous influenza vaccination.
  • Use of an influenza antiviral medication within 4 weeks of vaccination.
  • Known hypersensitivity and/or allergy to any drug or vaccine.
  • Known hypersensitivity to egg proteins (eggs or egg products), chicken proteins, or any of the components of the commercial vaccine (e.g., formaldehyde, and octoxinol 9 (Triton X-100) and neomycin).
  • Persons deficient in producing antibodies, whether due to genetic defect, immunodeficiency disease, or immunosuppressive therapy.
  • History of any bleeding disorder or subjects with thrombocytopenia (since bleeding may occur following an intramuscular administration to these subjects).
  • Any clinically significant abnormality upon physical examination or in the clinical laboratory tests at screening visit which, according to the physician's judgment, might confound the results of the study or pose additional risk to the subject by participation in the study.
  • Positive serology for HIV, HCV antibody or HBsAg.
  • Any acute medical situation (e.g. acute infection, ongoing flu symptoms) with or without fever within 48 hours of vaccination, which is considered significant by the Investigator.
  • Subjects who participated in another interventional clinical study within 30 days prior to first dose
  • Subjects who are non-cooperative or unwilling to sign consent form.
