There are vaccines for smallpox, polio, and hepatitis—but what about a vaccine for cancer? We're closer to it than you think… At the Mayo Clinic, doctors are beginning to test new vaccines targeting a protein that's abundant in both ovarian and breast cancers. The drug immunizes patients immediately after therapy, when they're healthy, to protect against relapse. "It creates memory cells that can be stimulated to destroy a tumor," says Dr. Keith Knutson with the Mayo Clinic.
