Scientists find exquisitely potent antibodies; a blood test may identify who needs steroids

Scientists have found 19 potent antibodies that "neutralize" the new coronavirus, including nine that exhibit "exquisite potency," according to a study published in Nature.Compared to previously isolated antibodies, some of the new ones can target different regions of the so-called spike that protrudes from the surface of the virus and helps it infect cells."Finding antibodies directed to different regions of the spike allows for more/better possibility of forming antibody cocktails to attach th
