Injecting the flu vaccine into a tumor gets the immune system to attack it

Joe_NoOne writes: From this perspective, the immune system's inability to eliminate tumor cells isn't only the product of their similarities to healthy cells. It's also the product of the signaling networks that help restrain the immune system to prevent it from attacking normal cells. A number of recently developed drugs help release this self-imposed limit, winning their developers Nobel Prizes in the process. These drugs convert a "cold" immune response, dominated by signaling that shuts things down, into a "hot" one that is able to attack a tumor.
