Researcher's at the Mayo Clinic in Arizona have sucuessfully created a vaccine that significantly reduces the size of tumors in breasts of mice as well as pancreatic cancer. This vaccine has a lot in common with how carbohydrate signatures that other ovarian cancers. When cells become cancerous, the carbohydrates that make up the cell wall become different, and almost all cancerous cells are distinguishable in that sense from healthy cells. So Scientists have been trying to teach the immune system to recognize that difference.This vaccine can do so in specific mice. It does this trick in three phases. Its tricks the immune system into thinking its a bacterial infection, then it motivates the antibody response, then it triggers the lymphocyte response.
