SARS-CoV-2 is a new member of the betacoronavirus (beta-CoV) genus, which also includes two common mild beta-CoVs and the life-threatening SARS-CoV-1 and MERS-CoV. Vaccines that elicit protective immunity against SARS-CoV-2 and beta-CoVs that circulate in animals could prevent future pandemics. Researchers designed a novel 24-mer SARS-CoV-2 receptor binding domain-sortase A conjugated nanoparticle vaccine (RBD-scNP). Investigators demonstrated that the immunization of macaques with RBD-scNP, and adjuvanted with 3M-052 and alum, elicits cross-neutralizing antibody responses against bat coronaviruses, SARS-CoV, and multiple SARS-CoV-2 variants of concern. This pioneering approach serves as a multimeric protein platform for the further development of generalized anti-beta-CoV vaccines. Supported by ORIP (U42OD021458), NIAID, and NCI.
