“Inescapable” COVID-19 Antibody Discovery – Neutralizes All Known SARS-CoV-2 Strains
Sci Tech Daily ^ | AUGUST 26, 2021 | LAWRENCE BERKELEY NATIONAL LABORATORY

Sotrovimab, the newest antibody therapy, was developed by GlaxoSmithKline and Vir Biotechnology after a large collaborative study by scientists from across the nation discovered a natural antibody (in the blood of a SARS survivor, back in 2003) that has remarkable breadth and efficacy.

Experiments showed that this antibody, called S309, neutralizes all known SARS-CoV-2 strains – including newly emerged mutants that can now “escape” from previous antibody therapies – as well as the closely related original SARS-CoV virus.

Jay Nix, leader of the Molecular Biology Consortium based at Berkeley Lab’s Advanced Light Source (ALS), used beamlines at the ALS and beamlines at SLAC’s Stanford Synchrotron Radiation Lightsource to perform X-ray crystallography on samples of survivor-derived antibodies during an early phase of the study. His work, alongside other crystallography and cryo-electron microscopy findings, helped generate detailed structural maps of how these antibodies bind to the SARS-CoV-2 spike protein, allowing the wider team to select the most promising contenders and advance them to cell culture- and animal-based studies. Following exciting lab results, the developers designed sotrovimab based on the structure of S309, and evaluated it in clinical trials.

The FDA granted an EUA for sotrovimab in late May after trials showed that people with mild to moderate COVID-19 infections who received an infusion of the therapy had an 85% reduction in rates of hospitalization or death, compared with placebo.

Actually, Trump and Giuliani got Regeneron but this is the same type of technology.

Now, that has the ring of truth to it :-)!
