A variant-proof SARS-CoV-2 vaccine targeting HR1 domain in S2 subunit of spike protein
文献摘要：
The emerging SARS-CoV-2 variants,commonly with many mutations in S1 subunit of spike(S)protein are weakening the efficacy of the current vaccines and antibody therapeutics.This calls for the variant-proof SARS-CoV-2 vaccines targeting the more conserved regions in S protein.Here,we designed a recombinant subunit vaccine,HR121,targeting the conserved HR1 domain in S2 subunit of S protein.HR121 consisting of HR1-linker1-HR2-linker2-HR1,is conformationally and functionally analogous to the HR1 domain present in the fusion intermediate conformation of S2 subunit.Immunization with HR121 in rabbits and rhesus macaques elicited highly potent cross-neutralizing antibodies against SARS-CoV-2 and its variants,particularly Omicron sublineages.Vaccination with HR121 achieved near-full protections against prototype SARS-CoV-2 infection in hACE2 transgenic mice,Syrian golden hamsters and rhesus macaques,and effective protection against Omicron BA.2 infection in Syrian golden hamsters.This study demonstrates that HR121 is a promising candidate of variant-proof SARS-CoV-2 vaccine with a novel conserved target in the S2 subunit for application against current and future SARS-CoV-2 variants.
