An experimental vaccine may help colorectal cancer patients battle the disease. This vaccine developed in the U.K. stimulated the production of killer T cells in up to 70 of colorectal cancer patients.

Researchers at the University of Nottingham cloned an antibody called 105AD7 from a patient with colorectal cancer who survived seven years with liver metastases.
