Researchers working toward one vaccine for many variants

Quote:Two separate research teams last week reported on laboratory tests of monoclonal antibodies that appear to protect against a broad range of COVID-19 virus variants. One study, published on Wednesday in The New England Journal of Medicine, identified "high-level, broad-spectrum" antibodies in blood samples from survivors of the original SARS outbreak in 2003 who recently received the Pfizer/BioNTech vaccine against SARS-CoV-2, the virus that causes COVID-19. In test tube experiments, some of the SARS survivors' antibodies induced by the vaccine could neutralize not only all of the current SARS-CoV-2 variants of concern, but also five viruses that have been identified in bats and pangolins and that have the potential to cause human infection. In a separate study, published on Thursday in the journal Immunity, another research team describes an antibody that was highly protective at low doses against a wide range of COVID-19-causing variants in mice.
