Human trials are underway and have yielded initial positive results in several trials of universal cancer vaccine that is believed to treat cancer by using a new technique that will activate the body’s immune system to fight any type of cancer in the body.
Positive results in trials of universal cancer vaccine show promise
This new vaccine, according to researchers works differently from traditional vaccines as this new process involves the administration of the vaccine to those who already have full blown cancer, as opposed to those that who still do not have it,
The process works by firing ‘darts’ infused with pieces of RNA derived from a patient’s cancer cells into the body;s own immune system that triggers an attack on any tumor that they encounter all over the body.
In a recent report published in the journal Nature, the team of researchers from the Johannes Gutenberg University of Mainz in Germany, pointed out that by modifying the RNA inside those ‘darts’ the team can theoretically mobilize the body’s own immune system to fight against any type of cancer,
These vaccines, according to researchers are relatively inexpensive and fast to produce, add to the fact that almost all antigen can be encoded by RNA
The process is called immunotherapy and although it is not a new practice the researchers are using this method to help the body‘s own immune system to fight cancer cells that could either stop cancer cell from multiplying or could even radically kill and stop cancer cells dead in their tracks.
It holds a lot of promise for the fight against cancer as separate immunotherapy tests conducted have shown great results, but current practice involving this method is morally done by genetically-engineering cancer-targeting immune cells in the lab and inoculating them back to the patient, which is more expensive and time-consuming.
This new technique however, involves the production of the vaccine in a lab and introduces the cancer DNA in the immune cells in the body making it less invasive and would allow the vaccine to be tweaked to address a certain type of range of cancer varieties.
The trials are now being conducted in three patients with melanoma and researchers are seeing very promising results with side effects limited only to flu-like symptoms, far better than most chemotherapy treatments available.
Although the trials of universal cancer vaccine still has a long way to go before more clinical trials are done and provide more conclusive evidence, it does show a ray of hope into how science can better harness more means to fight cancer.
