A new antibody theory can reportedly neutralize all COVID-19 strains and coronavirus, paving the way for stopping COVID-19

A team of researchers may have found an antibody that can neutralize all known novel coronavirus strains, including the developing variants. GlaxoSmithKline and Vir Biotechnology recently conducted a huge collaborative study by scientists and developed a new antibody therapy, called Sotrovimab. During the project, they discovered a new natural antibody “that has remarkable breadth and efficacy,” according to the Berkeley Lab.

The scientists reportedly discovered a new antibody, called S309, which “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,” according to a press release from the Berkeley Lab. Structural biologist Jay Nix, who was involved with the project, said the antibody can potentially stop all coronaviruses similar to COVID-19.

The researchers want to do more tests with the antibodies using hamsters. They hope to give it prophylactically but it’s unclear when that would be. “And, due to the unique binding site on mutation-resistant part of the virus, it may well be more difficult for a new strain to escape,” he said in a release from Berkeley Lab. The information about the antibody was published in the journal Nature.

A similar study recently published in the New England Journal of Medicine said that researchers found “high-level, broad-spectrum” antibodies in blood samples from SARS outbreak survivors in 2003, as I explained for the Deseret News. Back in 2020, scientists at the University of Pittsburgh School of Medicine discovered “the smallest biological molecule” that “completely and specifically neutralizes” the novel coronavirus, too, as I wrote for the Deseret News. The scientists developed a drug, called Ab8, that would be used as a preventative measure against COVID-19, according to Fox News.
