Abstract

Provided is a SARS-CoV-2 mRNA vaccine, and the preparation method and use thereof. The present invention provides an mRNA molecule capable of encoding a target polypeptide, wherein the target polypeptide comprises an NTD-RBD natural domain in the Spike (S) protein of SARS-CoV-2, and wherein the NTD-RBD natural domain comprises an NTD fragment and an RBD fragment, the NTD fragment and the RBD fragment being linked together via a natural amino acid sequence derived from the S protein as a linker. The present invention provides an mRNA encoding a NTD-RBD natural domain in the Spike protein of SARS-CoV-2, which achieves an immune effect against SARS-CoV-2 mutant strains and is widely applicable.
