Super vaccine to knock out 70% cancers!

LONDON: A super shot that could knock out seven out of ten lethal cancers is on the way. According to the researchers, it shrunk breast tumors by 80% during tests & could also tackle pancreatic, prostate, ovarian & even bowel cancers.

According to the Daily reports, even tumors that resist treatment with the best medicines available, including the wonder drug "Herceptin", may give in to the vaccine.

Sandra Gendler, study co-author & professor of molecular biology at the Mayo Clinic, said that cancer cells have a special way of thwarting the immune system by putting sugar on the surface of tumor cells so they can travel around the body without being detected. She also said that to enable the immune system to recognize the sugar, it took a special vaccine that had three parts to it & that turned out to be a winning combination. 

Geert-Jan Boons, a professor & a co-author of her, said that this vaccine elicits a very strong immune response. It activates all three components of the immune system to reduce tumor size by an average of 80%.

The experiments were based on mice but researchers hope a trial on people within two years. If they are successful, the vaccine could be available by 2020. The search for cancer vaccines has until now hampered by fears that healthy tissue would be destroyed with tumors. 

Accordingly, Gendler with associates from the University of Georgia focused on a protein called MUC1 that is made in bigger amounts in cancerous cells than in healthy ones. Not only is there more of it, but a sugar that is decorated with has a distinctive shape. The vaccine trains the immune system to recognize the rogue sugar & declare war against the cancer.
