In the absence of vaccines or antiviral drugs, researchers at Johns Hopkins University in Baltimore say the key to slowing and treating the coronavirus might be hidden in the blood of those who’ve already recovered from the disease.
“I’m an infectious disease doctor who is interested in history,” Casadevall said. “I knew the history of what was done in the early 20th century with epidemics. 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.”
