This phase I trial studies the side effects and best dose of a vaccine therapy in preventing
cancer from coming back in patients with non-metastatic, node positive, human epidermal
growth factor receptor (HER)2 negative breast cancer in which all signs and symptoms have
disappeared. Vaccines made from deoxyribonucleic acid (DNA) may help the body build an
effective immune response to kill tumor cells. Giving multiple vaccinations may make a
stronger immune response and prevent or delay the return of cancer.
