Inclusion Criteria

• •* For patients following radical prostatectomy: rising PSA after surgical procedure. (Patients must have a PSA greater than or equal to 0.8 ng/ml)
• •Eastern Cooperative Oncology Group (ECOG) performance status of 0 1 (Karnofsky greater than or equal to 80%).
• •Patients must have a PSA doubling time of 5-15 months.
• •Patients must have a rising PSA as confirmed by 3 values done at least 1 week apart and over no less than 1 month.
• •Recovery from acute toxicity related to prior therapy, including surgery and radiation, or no toxicity greater than or equal to grade 2.
• •Negative computed tomography (CT) scan/magnetic resonance imaging (MRI) and bone scan for metastatic prostate cancer.
• •Hematological eligibility parameters (within 16 days before starting therapy)
• •* Granulocyte count greater than or equal to 1000/mm\^3
• •* Platelet count greater than or equal to 100 000/mm\^3
• •* Hemoglobin (Hgb) greater than or equal to 10g/dL
• •Biochemical eligibility parameters (within 16 days before starting therapy):
• •--Hepatic function: bilirubin less than or equal to 1.5mg/dL (OR in patients with Gilbert's syndrome normal.
• •No other active malignancies within the past 36 months (with the exception of nonmelanoma skin cancers or carcinoma in situ of the bladder) or life-threatening illnesses, in the opinion of the investigator
• •Willing to travel to the National Institutes of Health (NIH), MSKCC, DFCI, BIDMC for follow-up visits.
• •18 years of age or older.
• •Able to understand and sign informed consent.
• •Baseline testosterone greater than or equal to 100 ng/dl
• •PSA less than or equal to 30 ng/mL.
• •The effects PROSTVAC on the developing human fetus are unknown. For this reason, men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study therapy and at least one month post therapy.
