Ages Eligible for Study:   18 Years to 40 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Male or female 18 to 40 years of age at the time of the vaccination.
  2. Subjects who the investigator believes can and will comply with the requirements of the protocol (e.g., return for follow-up visits and completion of the data collection tool).
  3. Available by telephone.
  4. Free of obvious health problems as established by medical history and clinical examination before entering the study.
  5. If subject is of childbearing potential, she must be abstinent or have used adequate contraceptive precautions (e.g., intrauterine contraceptive device; oral contraceptives or other equivalent hormonal contraception) for 30 days prior to vaccination. She must also have a negative pregnancy test at study entry and must agree to continue such precautions for two months after completion of vaccination.
  6. Must provide written, informed consent.

Exclusion Criteria:

  1. Use of any investigational or non-registered product (drug or vaccine) other than the study vaccine(s) within 30 days preceding the administration of the study vaccine, or planned use during the study period.
  2. Has received any other licensed vaccines within 4 weeks prior to enrollment in this study.
  3. Has received any influenza vaccine within the prior 12 month period.
  4. Has received any investigational vaccine designed for protection against avian influenza.
  5. Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the administration of the study vaccine. The use of inhaled and nasal steroids will be permitted.
  6. Any medically diagnosed or suspected immunodeficient condition based on medical history and physical examination.
  7. Administration of immunoglobulins and/or any blood products within the three months preceding the administration of the study vaccine or during the study.
  8. Acute disease at the time of enrollment. Acute disease is defined as the presence of a moderate or severe illness with or without fever ≥ 100.5º F.
  9. Acute clinically significant pulmonary, cardiovascular, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests.
  10. Major congenital defects or serious chronic illness.
  11. History of any neurological disorders or seizures, with the exception of febrile seizures during childhood.
