Date Time New research may be key to making safe, durable COVID-19 vaccines Representative microscopy image of SARS-CoV-2 infected cells stained with antibodies in convalescent plasma. Image credit: Dr Michael Joyce, University of Alberta. Using convalescent plasma, Griffith University researchers have identified how it may be possible to make a future vaccine that will provide protection against all major strains of COVID-19. Vaccines work by inducing antibodies that block the interaction between the receptor binding domain (RBD) of SARS-CoV-2’s Spike protein and its receptor, angiotensin converting enzyme 2 (ACE2), which is present on human lungs. To understand how antibodies block infection, the researchers from the Institute for Glycomics, with colleagues from the Gold Coast University Hospital, the University of Queensland, the University of Alberta, Canada, and Olymvax Pharmaceuticals, Chengdu, identified the minimal sequences of the RBD recognised by antibodies.
