A promising strategy in the fight against cancer is to use the body’s own immune system to remove tumor cells, but due to a phenomenon called immune tolerance, the immune system has a difficult time identifying which cells to attack. In the new study, scientists built upon previous discoveries that a safe, non-reproducing vaccine strain of T...
