Researchers are sifting through millions of antibodies produced by those who have recovered from COVID-19 to find which ones neutralize the virus. The team has already identified several antibodies that block coronavirus from interacting with its receptors.
Johns Hopkins University researchers propose using antibodies from the plasma or serum of those who have recovered from COVID-19 to help boost the immunity of newly infected patients and for those at risk of contracting the disease. Researchers say the antibodies may bind to and neutralize SARS-CoV-2. The technique has been proven successful in prior outbreaks, including the SARS epidemic and the 1918 flu pandemic.
