Vaccine Therapy, Trastuzumab, and Vinorelbine in Treating Patients With Locally Recurrent or Metastatic Breast Cancer

RATIONALE: Vaccines made from a person's white blood cells may help the body build an effective immune response to kill tumor cells. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as vinorelbine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vaccine therapy together with trastuzumab and vinorelbine may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving vaccine therapy together with trastuzumab and vinorelbine works in treating patients with locally recurrent or metastatic breast cancer.
