In an interesting change of events, scientists say vaccines could hold the key—not just to a cure but to wiping out cancer forever. Shari Baker, who was diagnosed with stage IV (metastatic) breast cancer in 2005, signed up for clinical trial at the University of Washington. A vaccine was injected into her upper arm; she got five more shots over the next five months. Today, with scans detecting no cancer anywhere, Baker seems to have beaten some extremely stiff odds."
