Putin announces cancer vaccines.. How do they work?.
Putin: We are very close to producing so-called cancer vaccines. There is no announced data about the Russian vaccines that Putin spoke about. But here we will provide information about the currently existing cancer vaccines, their types, and how they work. Cancer vaccines can be manufactured in 3 main ways. They can be made from the affected person's own cancer cells. Stem cell vaccines stimulate your immune system to respond to an antigen found on cancer cells, for example. T-Vec is used to treat some men with advanced prostate cancer.
