Scientists have found people resistant to COVID-19

Scientists have found people immune to COVID-19. These include those who fell ill during the SARS epidemic in China in 2003, according to an international group of scientists published in the journal Nature.

Scientists came to this conclusion as a result of a blood test taken from patients who had SARS-CoV-1 with SARS. They found antibodies in the blood that developed after recovery – and which can block a new type of coronavirus, SARS-CoV-2, the causative agent of COVID-19 infection.

Researchers studied monoclonal antibodies that were produced by the human body after SARS-CoV-1 infection. In particular, the S309 antibody – its target is protein spikes, with the help of which a new type of coronavirus binds to a healthy cell in the human body.

The destruction of these spikes leads to the fact that the SARS-CoV-2 virus cannot contact the cell and, as a result, infect a person. Work has shown that S309 effectively fights both the first and second SARS viruses.

Now scientists are working on the isolation of other antibodies – together they can be used to treat the most severe forms of COVID-19 disease, as well as to prevent infection of people at risk.
