Brief Summary
RATIONALE: Studying the immune response to a vaccine made from HER2/neu protein may help doctors plan better treatment for patients with breast cancer that overexpresses HER2. PURPOSE: This clinical trial is studying the immune response in patients who have undergone vaccine therapy for stage III or stage IV breast cancer that overexpresses HER2.

Outcome Measures
Primary Outcomes (1)
Immunologic memory response to HER-2/neu (HER2) intracellular domain protein
6 months after active immunization
Secondary Outcomes (2)
Characterization of memory T-cell population by intracellular cytokine staining
3, 6, and 12 months after active immunization
Quantitate memory precursor frequency by intracellular cytokine staining
3, 6, and 12 months after active immunization
Interventions
300mcg (100mcg/peptide) of the HER2 ICD peptide mixture per skin test. This will be injected intradermally on the back at 6 months post active immunization.
This is a laboratory test used to assess the antigen specific T cell population.
This is a laboratory test used to identify CD3+, CD4+, CD45R0+, CD8+, and DC1a+ present in the skin biopsy.
A 3mm punch biopsy is taken of the vaccine site. This is taken for laboratory analysis for immunohistochemical staining.
100mcg of sterile water will be administered intradermally on the back and serves as a negative control for the laboratory analysis. This will be injected intradermally on the back at 6 months post active immunization.
