They didn’t have vaccines then, they didn’t have any drugs then — just like the situation we face now. But physicians then knew that, for certain conditions, you could take the blood of the immune and use it to prevent disease or treat those who became ill.”Researchers doing coronavirus antibodies test from the blood of previously infected
