Scientists isolate powerful SARS-CoV-2 -neutralizing antibodies from COVID-19 patients

A new study has shown that potent antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) could help protect against COVID-19 infection. Preliminary results in animal studies have so far proven successful. The study titled, "Isolation of potent SARS-CoV-2 neutralizing antibodies and protection from disease in a small animal model," was published in the latest issue of the journal Science.
