Brief Summary
This phase Ib trial studies the side effects and best dose of a vaccine called H2NVAC before surgery in treating patients with HER2 expressing ductal carcinoma in situ. H2NVAC is a vaccine designed to stimulate specialized white blood cells in hopes of increasing immune response and protecting against breast cancer.

Outcome Measures
Primary Outcomes (2)
Adverse events
Number of adverse events reported, measured using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0
2 years
Dose limiting toxicities
Measured using criteria from the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0 with grade \>= 3 allergic reaction, grade \>= 3 autoimmune reaction (except for autoimmune encephalitis grade \>=4), grade \>= 3 injection site reaction manifesting as an ulceration, grade \>= 3 neurologic problem, grade \>= 3 non-hematologic or cardiac toxicity, or changes in left ventricular ejection fraction (LVEF) as specified per protocol.
14 days post vaccination, 2 years
Study Arms (1)
Treatment (multi-epitope HER2 peptide vaccine H2NVAC, GM-CSF)
EXPERIMENTALPrior to standard of care surgery, patients treated at dose levels 1 and 2 receive GM-CSF admixed with multi-epitope HER2 peptide vaccine H2NVAC intradermally on day 1 of each cycle. Treatment repeats every 14 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients treated at dose level 3 receive GM-CSF admixed with multi-epitope HER2 peptide vaccine H2NVAC intradermally on days 1, 4, 8, and 15 for 1 cycle. Patients also undergo ECHO and collection of blood samples throughout the trial and may undergo biopsy on trial.

Eligibility Criteria
You may qualify if:
- Eastern Cooperative Oncology Group (ECOG) performance status =\< 2
- Patients must not have received any prior therapy for current DCIS
- Note: Patients who received tamoxifen, raloxifene, aromatase inhibitor or another agent for prevention of breast cancer may be included as long as the patient has discontinued the treatment at least 2 months prior to baseline study biopsy if they chose to have this collected
- Note: Concurrent use of endocrine therapy during the vaccination/preoperative period is not allowed. However, standard adjuvant endocrine therapy with tamoxifen or aromatase inhibitor after completion of vaccination and surgery is allowed
- Any degree of HER2 expression as performed on the diagnostic clinical biopsy defined by immunohistochemistry +1, +2, or +3
- Histologically confirmed un-resected operable ductal carcinoma in situ with no evidence of lymph node involvement or distant metastasis
- Note: suspected microinvasion or definite microinvasion (\< 0.1 mm invasion) on core biopsy is allowed
- Patients will be asked to have an additional research biopsy prior to the first vaccination. This is not mandatory for participation
- Patients must have evidence of at least 0.5 cm of disease extent based on mammogram, ultrasound, or magnetic resonance (MRI) imaging
- Absolute neutrophil count (ANC) \>= 1500/mm\^3 (less than or equal to 28 days prior to registration)
- Platelet count \>= 75,000/mm\^3 (less than or equal to 28 days prior to registration)
- Hemoglobin \>= 9.0 g/dL (less than or equal to 28 days prior to registration)
- Creatinine =\< 2 x upper limit of normal (ULN) (less than or equal to 28 days prior to registration)
- Serum glutamic-oxaloacetic transaminase (SGOT) (aspartate aminotransferase \[AST\]) =\< 2 x ULN (less than or equal to 28 days prior to registration)
- Albumin \>= 3 g/dL (less than or equal to 28 days prior to registration)
- +8 more criteria
You may not qualify if:
- Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown:
- Pregnant women
- Nursing women unwilling to stop breast feeding
- Women of child bearing potential who are unwilling to employ adequate contraception from the time of registration through 6 months after the final vaccine cycle
- Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
- Immunocompromised patients including patients known to be human immunodeficiency virus (HIV) positive or those on chronic steroids, unless physiologic replacement for adrenal or pituitary insufficiency
- Note: Must be off systemic steroids greater than or equal to 90 days prior to Registration. However, topical steroids, inhalants or steroid eye drops are permitted
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Uncontrolled acute or chronic medical conditions including, but not limited to the following:
- Active infection requiring antibiotics
- Congestive heart failure with New York Heart Association class III or IV moderate to severe objective evidence of cardiovascular disease
- Myocardial infarction or stroke less than or equal to 6 months prior to registration
- Receiving any other investigational agent
- Other active malignancy at time of registration or less than or equal to the last three years prior to registration. EXCEPTIONS: Non-melanoma skin cancer or carcinoma-in-situ (e.g. of cervix, prostate)
- NOTE: If there is a history of prior malignancy, they must not be receiving other specific treatment (cytotoxics, monoclonal antibodies, small molecule inhibitors) for their cancer
