Cancer Vaccine treats existing cancer and prevents cancer recurrence

The primary goal of cancer vaccine is to treat cancer that already exists and prevent the chance of cancer from coming back. Cancer vaccine helps stimulate the immune system in the body that destroys the existing cancer cells. Normally, cancer cells have the mechanism that hinders white blood cells to attack them. Immunotherapy is used to turn off this switch, allowing the white blood cells to destroy the cancer cells more effectively. But immunotherapy will not be effective at all if white blood cells don’t recognize the cancer cells and they will flow away. This is where cancer vaccine comes into play. It triggers as many white blood cells as possible to keep them close to the cancer cells as they have already recognized them. And once immunotherapy is given after that, the white blood cells will do an even better job of destroying the cancer cells.
