A CRITIQUE ON CANCER VACCINE

The goal of a successful vaccine is to prepare the immune system for invasion of a foreign pathogen and teach them to recognize antigens as well as reduce the risk of transmission. In the field of cancer, vaccines are found to be the latest discovery. Provenge? (Sipuleucel-T) is the only vaccine approved by Food and Drug Administration for the treatment of cancer. Vaccines are an appealing therapeutic strategy because they are specific. In addition they stimulate the adaptive immune system, thereby producing a memory response allowing for sustained effect without repeated therapy. Revelation of a potential anticancer treatment is as yet a test to the researchers. Thus, the development of effective cancer vaccines require, thoughtful clinical trials, and scientific progress which might induce long-term specific anticancer response and could contribute to effective and lasting elimination of malignant cells.
