And that includes a simple infection from the common flu or the common cold. So because our immune system is suppressed it not only is not capable of fighting that graft but it also can't actually fight off any type of infection. So people that are immunosuppressed can sometimes die from the common cold or the flu because their immune system is not capable of mounting any type of defense or response. On top of that immunosuppressed people are also much more likely to actually develop cancer. And that's because cells like natural T cells and cytotoxic T cells are the cells that fight off the cancer developing cells. And because our system is immunosuppressed that means those cells cannot find those cancer cells.
