   multidose vials used)

   3. Life-threatening reactions to previous influenza vaccinations

   4. Active systemic or serious concurrent illness, including febrile illness on the day of
   vaccination

   5. History of immunodeficiency

   6. 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.

   7. Blood pressure >150 systolic or > 95 diastolic at Visit 1

   8. Hospitalization in the past year for congestive heart failure or emphysema.

   9. Chronic Hepatitis B or C

10. 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.

11. 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).

12. 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.

13. History of blood dyscrasias, renal disease, or hemoglobinopathies requiring regular
   medical follow up or hospitalization during the preceding year

14. 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.

15. Receipt of blood or blood products within the past 6 months

16. Medical or psychiatric condition or occupational responsibilities that preclude
   subject compliance with the protocol

17. Inactivated vaccine 14 days prior to vaccination

18. Live, attenuated vaccine within 60 days of vaccination

19. History of Guillain-Barre Syndrome
