I've heard people call Dendreon's new prostate cancer therapy, Provenge, a "vaccine". Interestingly, the official website doesn't mention it, but the description of it does sound sort of vaccine-like in a lot of ways: "PROVENGE is the only FDA-approved autologous cellular immunotherapy indicated for the treatment of asymptomatic or minimally symptomatic metastatic castrate resistant (hormone refractory) prostate cancer. PROVENGE is designed to work differently from hormone therapy or chemotherapy. By stimulating the natural ability of your body’s immune cells to target and attack advanced prostate cancer, PROVENGE may help you live longer."
