Volunteer has received any of the following substances: 2. Immunosuppressive medications, cytotoxic medications, inhaled corticosteroids, or long-acting beta-agonists within the past three months. \[Note: The following will NOT exclude study participation: use of corticosteroid nasal spray for rhinitis topical corticosteroids for an acute uncomplicated dermatitis short-acting beta-agonists in controlled asthmatics a short course (10 days or less) of corticosteroids for a non-chronic condition completed at least 2 weeks prior to enrollment in this study\] 3. Blood products within 120 days prior to HIV screening 4. Immunoglobulin within 60 days prior to HIV screening 5. Live attenuated vaccines within 30 days prior to initial study vaccine administration 6. Investigational research agents within 30 days prior to initial study vaccine administration 7. Medically indicated subunit or killed vaccines, e.g. influenza, pneumococcal, or allergy treatment with antigen injections, within 14 days of study vaccine administration 8. Current anti-TB prophylaxis or therapy 9. Previous H5 avian influenza investigational vaccine. Volunteer has a history of any of the following clinically significant conditions: 10. Autoimmune disease or immunodeficiency. 11. Serious adverse reactions to vaccines such as anaphylaxis, urticaria (hives), respiratory difficulty, angioedema, or abdominal pain. 12.

Idiopathic urticaria within the past 2 years 17. Hypertension that is not well controlled by medication or is more than 145/95 at enrollment. 18. Bleeding disorder diagnosed by a doctor (e.g. factor deficiency, coagulopathy, or platelet disorder requiring special precautions) or significant bruising or bleeding difficulties with injections or blood draws. 19. Malignancy that is active or treated malignancy for which there is not reasonable assurance of sustained cure or malignancy that is likely to recur during the period of the study. 20. Seizure disorder other than: 1) febrile seizures under the age of two, 2) seizures secondary to alcohol withdrawal more than 3 years ago, or 3) a singular seizure not requiring treatment within the last 3 years. 21.
