A new prostate DNA- based cancer vaccine has been developed by the researchers of Cancer Research UK and the University of Leeds, which is claimed to reduce the disease to a constant illness rather than a fatal disease.

The researchers believed that the prostate DNA vaccine was able to clean out the tumor as the vaccine produced a good amount of prostate antigens in the blood which further boosted the immune system which did not let the tumor grow, thereby resulting in complete destruction of the tumor. The vaccine would increase the life expectancy of people contracted with cancer with the disease under control.

In an experiment the researchers injected the vaccine into the bloodstream of the mice with prostate cancer, as a result the immune system started responding the vaccine solution and destroyed the tumor that too without harming the healthy cells. The vaccine was also helpful in treating melanoma and the vaccine was able to treat the various forms of cancer in lungs, brain and pancreas.

A dose of nine injections cured 80% of the mice, moreover, the trials on human were not done as yet. Professor Peter Johnson, Cancer Research UK's Chief Clinician, said: "This is an interesting and significant study which could really broaden out the field of immunotherapy research".
