Cellular immune responses in vaccinated patients. Peripheral blood mononuclear cells were collected at the indicated day (D) or month (M) following initial immunization. Peripheral blood mononuclear cells were co-cultured with CMMT 110/C1 cells infected with a multiplicity of infection (MOI) of 40 plaque-forming units (pfu)/cell of fowlpox virus expressing CEA, MUC-1 and TRICOM (Black), or fowlpox virus expressing PSA and TRICOM; (Grey). *Denotes two-fold increase of CEA/MUC-1-specific T cell response compared to PSA control.
