Inclusion Criteria: Tumor Type * Unresectable low-grade gliomas that have received at least two chemotherapy/biologic regimens. Radiation therapy counts as a biologic regimen. Patients may not have received radiation therapy to the index lesion within 1 year of enrollment. Patients may have tumor spread within the central nervous system (CNS). * HLA-A2 positive based on flow cytometry. * Patients must be clinically stable and off or on low-dose (no more than 0.1 mg/kg/day, max 4 mg/day Dexamethasone) corticosteroid for at least one week prior to study registration. * Patients must be ≥ 12 months and \< 22 years of age at the time of HLA-A2 screening. * Patients must have a performance status of ≥ 70; (Karnofsky if \> 16 years and Lansky if ≤ 16 years of age. * Documented negative serum beta-human chorionic gonadotropin (HCG) for female patients who are post-menarchal. Because the effect of the peptide-based vaccine and poly-ICLC on the fetus has not sufficiently been investigated, pregnant females will not be included in the study. * Patients must be free of systemic infection requiring IV antibiotics at the time of registration. Patients must be off IV antibiotics for at least 7 days prior to registration. * Patients with adequate organ function as measured by: Bone marrow: absolute neutrophil count (ANC) \> 1,000/µ; Platelets \> 100,000/µ (transfusion independent); absolute lymphocyte count of ≥ 500/µ; Hemoglobin \>8 g/dl (may be transfused). Hepatic: bilirubin \< 1.5x institutional normal for age; serum glutamate pyruvate transaminase (SGPT) \< 3x institutional normal. * Renal: Serum creatinine based on age or Creatinine clearance or radioisotope glomerular filtration rate (GFR) ≥ 70 ml/min/ml/min/1.73 m² * Patients must have recovered from the toxic effects of prior therapy to grade 1 or better. Patients must be at least 3 weeks from the last dose of standard cytotoxic chemotherapy or myelosuppressive biological therapy and at least 1 week from the last dose of non-myelosuppressive biologic therapy. * No overt cardiac, gastrointestinal, pulmonary or psychiatric disease. Exclusion Criteria: * Patients living outside of North America are not eligible. * Patients may not have received radiation to the index lesion within 1 year of enrollment. * Concurrent treatment or medications (must be off for at least 1 week) including: * Interferon (e.g. Intron-A®) * Allergy desensitization injections * Growth factors (e.g. Procrit®, Aranesp®, Neulasta®) * Interleukins (e.g. Proleukin®) * Any investigational therapeutic medication * Patients must not have a history of, or currently active autoimmune disorders requiring cytotoxic or immunosuppressive therapy, or autoimmune disorders with visceral involvement. * Use of immunosuppressives within four weeks prior to study entry or anticipated use of immunosuppressive agents. Dexamethasone, or other corticosteroid medications, if used in the peri-operative period must be tapered to no more than 0.1 mg/kg/day, max 4 mg/day dexamethasone for at least one week before study registration. Topical corticosteroids are acceptable. * Because patients with immune deficiency are not expected to respond to this therapy, HIV-positive patients are excluded from the study. * Patients who have received prior immunotherapy.
