Those person who recoverd from COVID-19, isolate there serum and identify antibodies against COVID-19, make copy and appy to model...... it is a hypothesis only.
Blood plasma from people who have recovered from COVID-19 was used in several countries to treat patients during outbreaks of coronavirus. This type of treatment is based on the idea that antibodies developed by recovered patients might strengthen the immune system of new patients.
complete study of the antibodies present in recovered covid-19 and non covid 19 patient can give an idea in development of stable therapeutic protein to treat covid 19 patients.
If some particulate antibody present only in recovered covid -19 patients can develop by recombination technology and use as a therapeutic drug.
