The United States has successfully developed a cancer vaccine, with a complete cure rate of 97%. This study does exist and was published in the journal Science Translational Medicine by Dr. Ronald Levy of Stanford University School of Medicine at the end of January 2018. However, the "cure rate of 97" is a complete misunderstanding.
The experimental results are indeed encouraging. Treatment experiments on animal lymphoma models showed that after 90 lymphoma mice were treated with this method, 87 were completely cured and their tumors disappeared completely. Although three mice relapsed, tumor growth was suppressed after retreatment. This therapy has also achieved good therapeutic effects on breast cancer, colorectal cancer, and skin cancer in animals.
It needs to be emphasized that this research is still in the animal (mouse) experimental stage. Of the 90 mouse models, 87 achieved good results. The converted cure rate is about 97, but This is just the cure rate for mice. The remarkable results in animal experiments do not mean that the same results can be achieved when applied to humans. According to information found on the clinical trial website, the research team began recruiting volunteer patients for phase 1 clinical trials in January 2018.
In fact, most of the results of animal experiments cannot be replicated in humans. There are thousands of papers on tumor research every year, and there are countless articles on effective animal experiments. However, after several or even more than ten years of clinical trials, treatments that are finally successful in human experiments are really "rare". Source: People's Daily Online
