                       6. Patients may be maintained on hormonal therapy provided there is clear
                       evidence of tumor progression

                       7. Have provided written informed consent.

                       Exclusion Criteria:

               1. Concurrent or recent chemotherapy (within 3 weeks), XRT within 3 weeks, may have
                  had immunotherapy in the past (off within 3 weeks), or general anesthesia/major
                  surgery (within 3 weeks). Patients must have recovered from all known or expected
                  toxicities from previous treatment and passed a treatment-free "washout" period
                  of 3 weeks before starting this program (8 weeks for persons receiving
                  nitrosourea or mitomycin).

               2. History of clinical hypersensitivity to GM-CSF, Interferon-alpha-2b (Merck),
                  yeast, beef, or to any components used in the preparation of the experimental
                  vaccine.

               3. BUN >30 and a creatinine >2.

               4. Absolute granulocyte count < 1000; platelets <100,000.

               5. Bilirubin >2.0; alkaline phosphatase >5x upper limit of normal (ULN); ALT/AST >2x
                  ULN.

               6. Proteinuria >1+ on urinalysis or >1 gm/24hr.

               7. Left ventricular ejection fraction (LVEF as determined by cardiac echo or MUGA
                  scan) below the normal limits of the institutions specific testing range. This
                  assessment may be repeated once at the discretion of the Investigator with the
                  approval of the Sponsor.

               8. New York Heart Association stage 3 or 4 cardiac disease.

               9. A pleural effusion of moderate severity or worse.

              12. Patients with concurrent second malignancy. Persons with previous malignancies
                  effectively treated and not requiring treatment for >24 months are eligible,
                  provided there is unambiguous documentation that current local recurrence or
                  metastatic site represents recurrence of the primary breast malignancy.

              13. Patients who are HIV positive (by self-report) or have clinical or laboratory
                  features indicative of AIDS.

              14. 14. Patients who require systemic steroids at a dose equivalent of >10 mg/day of
                  prednisone. Beta-blocker therapy, while not exclusionary, is discouraged and
                  alternatives should be sought if possible. The beta-blocker might compromise use
                  of epinephrine for the rare possibility of anaphylaxis. Anticoagulants must be
                  approved by the Investigator with notification of the Sponsor.

              15. Patients who are on treatment for rheumatological or autoimmune disease unless
                  approved by the Investigator in consultation with the Sponsor (e.g., as for
                  replacement therapy for autoimmune thyroiditis or diabetes).

              16. Patients with severe psychiatric (i.e. schizophrenia, bipolar, or borderline
                  personality disorder) or other clinically progressive major medical problems,

              17. Male breast cancer patients.

              18. Patients may not be on a concurrent clinical trial, unless approved by PI.
