Disclosed herein are embodiments of a compound useful for treating or preventing betacoronavirus infections such as SARS-Cov-2 infections. Also disclosed is a method for administering the compound to a subject, particularly a human subject, to treat or prevent a betacoronavirus infection in the subject. The compound can comprise an oligomer comprising a nucleic acid base sequence that is antisense to at least a portion of a SARS-CoV-2 genomic RNA, and can comprise a sequence present in the 5′ UTR and first 20 nt of coding sequence of the SARS-CoV-2 genomic RNA. The compound also can contain a peptide sequence. In some embodiments, the compound is a peptide-conjugated phosphorodiamidate morpholino oligomer (PPMO).

A recombinant SARS-CoV2 protein-based vaccine, and method of immunizing, is developed by either embedding the epitopes/domains, or chemically attaching, to an already established vaccine candidate, such as a detoxified recombinant tetanus neurotoxin (DrTeNT), to develop a novel vaccine to immunize against SARS-CoV2. The developed vaccine will have three novel contributions compared to the present vaccine technology; a) providing a novel and very effective vaccine platform; b) priming with DrTeNT will prepare the host immune system for better response; and c) oral delivery of the vaccine candidate with a group of neurotoxin binding proteins (NAPs) from Clostridium sp. A Detoxified recombinant tetanus neurotoxin (DrTeNT) is prepared by mutation of the active site amino acid residues is an effective vaccine candidate, and is to be used for embedding epitopes of SARS-CoV-2 virus protein for vaccination against Covid-19. DrTeNT is a risk-free vaccine, free of formalin or any other chemical adjuvants.
