- Life-threatening reactions to previous influenza vaccinations
- Active systemic or serious concurrent illness, including febrile illness on the day of vaccination
- History of immunodeficiency
- Known or suspected impairment of immunologic function, including, but not limited to, clinically significant liver disease, diabetes mellitus treated with insulin, moderate to severe renal disease or any other chronic disorder which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
- Blood pressure >150 systolic or > 95 diastolic at Visit 1
- Hospitalization in the past year for congestive heart failure or emphysema.
- Chronic Hepatitis B or C
- Recent or current use of immunosuppressive medication, including glucocorticoids (corticosteroid nasal sprays and inhaled steroids are permissible). Use of oral steroids (<20mg prednisone-equivalent/day) may be acceptable after review by the investigator.
- Malignancy, other than squamous cell or basal cell skin cancer (includes solid tumors such as breast cancer or prostate cancer with recurrence in the past year, and any hematologic cancer such as leukemia).
- Autoimmune disease (including rheumatoid arthritis treated with immunosuppressive medication such as Plaquenil, methotrexate, prednisone, Enbrel) which, in the opinion of the investigator, might jeopardize volunteer safety or compliance with the protocol.
- History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular medical follow up or hospitalization during the preceding year
- Use of any anti-coagulation medication such as Coumadin or Lovenox, or anti-platelet agents such as aspirin, Plavix, Aggrenox must be reviewed by investigator to determine if this would affect the volunteer's safety.
- Receipt of blood or blood products within the past 6 months
- Medical or psychiatric condition or occupational responsibilities that preclude subject compliance with the protocol
- Inactivated vaccine 14 days prior to vaccination
- Live, attenuated vaccine within 60 days of vaccination
- History of Guillain-Barre Syndrome
