This trial will test how safe this vaccine is. It also tests whether its introduction induces an immune response by stimulating the patient's own immune system to recognize a specific target molecule called HER2, which is overexpressed in many breast cancers.

The vaccine in this trial has not previously been administered to humans, and therefore the induction of the desired immune responses in humans remains to be established. Patients will receive 6 intramuscular vaccinations over a 14 week period, with 9 clinic visits and 3 follow up visits. In addition, patients are asked to revisit the study physician once a year for 5 years after the study ends to evaluate any long-term effects.
