Cancer vaccines

Scientists have developed the first in the history of medicine, vaccine, implanted under the skin of the patient, which can destroy malignant cancerous tumors in the body.

In experiments with mice, specialists proved that the new vaccine is able to fundamentally change the immune system and completely remove the melanoma. In this healthy tissue is not applied absolutely no harm.

In addition, as a result of the impact of vaccines in the body formed long-term immunity to cancer cells, like immune to the virus or bacteria, thus avoiding the re-development of cancer.

The container with the vaccine is a disc made of porous polymer, voids which are filled by special molecules. In humans, these molecules are activated and inform the immune system on what is necessary to destroy cancer cells.

“That we have developed a vaccine is a good combination of engineering and immunological approach to cancer treatment,” – said one of the authors, Harvard University professor David Mooney.

We note a similar approach to the destruction of cancer known long ago, but so far all attempts to obtain well-functioning cancer vaccine proved to be unsuccessful. The fact that cancer is not recognized by cells of the immune system as alien tissue.

Previously, the classical approach to medical treatment of cancer involves the separation of immune cells from the body, reprogramming them to attack cancer cells and return the body of the patient. In this approach, more than 90% of the cells did not live up to the moment of implantation in the human body, but because cancer vaccines so far remained unsuccessful.
