Has a cancer vaccine been developed?
Different types of cancer kill millions of people around the world and cause millions of deaths, but now experts have had some success in developing a vaccine.
According to the international website, the initial trial of a vaccine for the prevention of cancer has been successful. In the first phase of the clinical trial of this vaccine PGV001, 13 patients were included who were suffering from solid tumors.
At the end of the trial, 4 patients had lost their symptoms and were not given any other therapy. There were 4 patients who were alive but were being given therapy while 3 people died.
Researchers at Mount Sinai Hospital in the United States presented the results of the trial at the annual meeting of the American Association for Cancer Research.
“Although there has been considerable progress in the treatment of cancer, we also know that most patients fail to achieve a solid clinical response,” experts said.
“Personalized vaccines will help improve patients’ immune responses,” he said. With this in mind, these experts developed a vaccine called PGV001, which is a type of amino acid, which was given to patients with initial treatment.
Of the 13 patients vaccinated, six were diagnosed with head and throat cancer, three with white blood cells, two with lung, one with breast and one with bladder cancer.
11 patients were given 10 doses of vaccine while 2 patients were given at least 8 doses.
Experts said that only 50% of the patients experienced minor side effects from the vaccine, ie 4 had an allergic reaction at the injection site and one had a mild fever.
The effects of the vaccine on these individuals were analyzed for an average of 880 days, during which time 4 patients lost evidence of cancer and did not need further therapy.
One of them had stage 3 lung cancer, one had stage 4 breast cancer, one had stage 2 bladder cancer and one had leukemia.
Four patients in the trial are still alive and undergoing various types of therapy, while three have died, two of whom have returned to cancer.
The experts said that the results show that the open wax pipeline is a good strategy for the development of a safe and personalized vaccine, which can be used to treat different types of tumors.
