Exclusion Criteria:

• Active infection requiring treatment with antibiotics.
• Existing diagnosis or history of organic brain syndrome that precludes participation in the full protocol.
• Existing diagnosis or history of significant impairment of basal cognitive function that might preclude participation in the full protocol.
• Other current malignancies. Subjects with prior history at any time of any in situ cancer, including lobular carcinoma in situ of the breast, cervical cancer in situ, atypical melanocytic hyperplasia or Clark I melanoma in situ, or basal or squamous skin cancer are eligible, provided they are disease-free of these other malignancies at the time of registration. Subjects with other malignancies - other than the one for which they are being treated - are eligible if they have been continuously disease free (from the old cancer) for ≥ 5 years prior to the time of registration.
• Existing diagnosis or history of autoimmune disorders or conditions of immunosuppression. This includes, but is not limited to, being treated with corticosteroids, including oral steroids (i.e. prednisone, dexamethasone [except when used as an antiemetic in standard therapy]), continuous use of topical steroid creams or ointments or any steroid-containing inhalers. Subjects who have been on systemic steroids will require a 6-week washout period. Subjects who discontinue the use of these classes of medication for at least 6 weeks prior to registration are eligible if, in the judgment of the treating physician, the subject is not likely to require these classes of drugs during the treatment period. Replacement doses of steroids for subjects with adrenal insufficiency are allowed.
• Pregnancy or breast feeding, due to the unknown effects of peptide/mimotope vaccines on a fetus or infant. Women of childbearing potential must have a negative urine pregnancy test within 72 hours prior to receiving the first dose of study drug, and must be counseled to use an accepted and effective method of contraception while on treatment and for a period of 18 months after completing or discontinuing treatment. Accepted methods include oral contraceptives, barrier method, IUDs, and abstinence.
