<qa>  What is the response rate of immunoization with 4 melanoma antigen peptidPurpose of investigation: Primary hypotheses: Immunization of patients with 4 melanoma antigen peptides will induce augmented specific IFN-y-producing CD8 T cells against all 4 antigens simultaneously. Immunization with 4 melanoma antigen peptides will increase the response rate from 10 to 30. Administration of low-dose IL-2 following each vaccine will result in a greater than 3-fold increase in specific T cells compared to no IL-2.
