Not legit. Sharing COVID data? Most recently, a team of scientists led by the University of Bonn in Germany reported newly discovered nanobodies that bind to SARS-CoV-2 and may prevent what is called mutational escape. Thats the ability of a virus to avoid immune responses by mutating, and a treatment that prevents the virus from doing so would guard against reinfection. And this gap in our knowledge brings much uncertainty about the future of the pandemic. No matter what variant the coronavirus has thrown at us, including omicron, prior exposure to the virus (through either vaccination or a prior infection) has still offered good protection against hospitalization and severe disease. Researchers are using the ultrabright X-rays of the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at DOEs Argonne National Laboratory, to help turn naturally generated llama antibodies into potentially effective therapies against SARS-CoV-2, the virus that causes COVID-19.
