Evaluation of antigen-specific cellular and humoral immune responses per antigen. Percentage of patients (n = 33) responding against each antigen contained in the vaccine by CD4 response, CD8 response, both CD4 and CD8 responses and either CD4 or CD8 responses. Tetramer responses were measured only in HLA-A2+ patients (n = 14), humoral responses were measured only against PSA and PSCA and could only be detected for PSA, 23 patients tested for anti PSCA antibodies showed no increase over time
