Persons with serologic evidence of hepatitis C infection that has cleared spontaneously, or with a history of treated hepatitis C with a sustained virologic response, can be enrolled. Persons with a history of resolved hepatitis B infection (negative for hepatitis B surface antigen) can be enrolled * History of a life-threatening allergic reaction (anaphylactic/anaphylactoid reaction) to any component of the vaccine * History of receipt of an organ transplant or hematopoietic stem cell transplant * Significant autoimmune disease such as rheumatoid arthritis, psoriatic arthritis, inflammatory bowel disease, multiple sclerosis, scleroderma, dermatomyositis, or other condition which in the past has required significant immune modifying medication or which has a clinical course that is characterized by relapses * Has immunosuppression as a result of an underlying illness (e.g. leukemia, lymphoma or other malignant neoplasms) or treatment with immunosuppressive or cytotoxic drugs, or use of anticancer chemotherapy or radiation therapy. * Has long-term use of oral or parenteral steroids (\>7 days), or high-dose inhaled steroids (\>800 mcg/day of beclomethasone dipropionate or equivalent) within the preceding 6 months (nasal and topical steroids are allowed) * Women of child-bearing potential only: pregnant, breastfeeding, or planning to become pregnant 3 months post vaccination * Has an acute or chronic medical condition that, in the opinion of the investigator, would render biopsies unsafe * History of coagulopathy or taking medication that may cause bleeding (long term high dose aspirin, heparin, coumadin).
