Passive antibody therapy appeared in the 1890s, and it has been widely used throughout the 20th century – during the treatment of measles, polio, mumps and flu.
During this instrument, patients with coronavirus must first donate blood during the illness, then during the end of the illness and after recovery. During this period, patients usually have a large amount of natural antibodies in their blood that are produced to fight the SARS-CoV-2 coronavirus.
As a rule, antibodies are in the blood of a person for a month, and in some cases even several years after infection. Moreover, in the future, such antibodies can be artificially propagated in laboratories and create vaccines from them.
Scientists note that antibodies will only work if it is officially proven that it is not possible to get the Covid-19 coronavirus infection again. So far, cases of re-infection with coronavirus in China have been recorded, however, many scientists attribute these data to an insufficiently high-quality virus testing system.
