Development of broad nanovaccines targeting diverse coronavirus receptor-binding sites

Project Summary The first project of our pan-CoV proposal is titled ‘Development of broad nanovaccines targeting diverse coronavirus receptor-binding sites’. Our team’s expertise will culminate in structurally guided coronavirus nanoparticle vaccines to broaden CoV vaccine protection. This proposal utilizes our novel platform to develop potent, RBS-focused nanoparticle vaccines to induce broad protection across CoV lineages, escape mutations and potential pandemic CoVs that are of concern. The project aims are: (1) Create a library of mutants that escape coronavirus immunity (2) Develop RBS-focused nanoparticle vaccines to induce broadly neutralizing antibodies to conserved sites using nucleic acid delivery and (3) Develop vaccine regimens to induce broad immunity and protection across diverse CoVs.
