Vidcast:  https://youtu.be/-4BkGgnnZe4   A bioengineered two-headed antibody constructed from a llama antibody to the SARS coronavirus prevents the CoVid19 virus from attaching to and infecting cells.  Virologists at the University of Texas-Austin worked for years on llama antibodies to SARS and MERS viruses and now report a way to repurpose them for our current coronavirus.   The llama anti-SARS antibody called VHH72 did also bind to CoVid19 but weakly.  Linking two of the VHH72 molecules together produced a novel antibody that did bind to CoVid19 spike protein preventing it from infecting tissue cultured cells while also continuing to block the SARS virus.  The investigators are beginning tests in animals.   Fingers crossed everyone.   https://www.sciencedaily.com/releases/2020/05/200501184301.htm   #covid #coronavirus #llama #antibody #sars
