In parallel with the creation of a vaccine against coronavirus, scientists around the world are looking for a cure for COVID-19. Moreover, first of all, drugs that are already used for other diseases are checked. So, scientists from Stanford found that the drug against hepatitis B allows you to strengthen the immune system of patients by acting on receptors in the lungs and intestines, writes the British newspaper Daily Mail. It is these organs that suffer most from the new virus. Scientists believe that the drug can protect people who tolerate mild COVID-19 from serious complications. And at the same time make them less dangerous for others.
