Disclosed herein is a live attenuated recombinant measles virus (rMeV)-based coronavirus vaccine containing a SARS-CoV-2 spike (S) protein that has at least one mutation to remove a glycosylation site. In some embodiments, the rMeVs-based coronavirus vaccine contains full-length stabilized pre-fusion and native S proteins, S proteins of SARS-CoV-2 variants, truncated S proteins lacking its transmembrane and cytoplasmic domains, S proteins lacking glycosylation sites, the monomeric and trimeric receptor-binding domain (RBD), the monomeric and trimeric S1 protein, Fc-fused RBD, or Fc-fused S1 protein. Also disclosed is a live attenuated recombinant coronavirus vaccine, wherein a stabilized prefusion spike (S) protein is inserted into a viral vector genome. |
