• HIV positive (by history or screening ELISA).
• Hepatitis B or C positive (by history or screening HBsAg/anti-HCV ELISA).
• Active or past internal organ, hematologic malignancy, or metastatic cutaneous malignancy.
• History of, or current autoimmune disease, including but not limited to systemic lupus erythematosus, scleroderma, and polyarteritis.
• Immunodeficiency or unstable medical condition as determined by baseline medical history, physical exam, and laboratory assessment.
• Received, or plans to receive, licensed live vaccines within 30 days of study vaccination.
• Received, or plans to receive, licensed killed vaccines within 14 days of study vaccination.
• Received, or plans to receive, immunoglobulin or other blood products within 60 days of study vaccination.
