Studied vaccines
RBD
NVSI-06-09 is a mosaic-type trimeric RBD vaccine, recombinantly expressed by Chinese hamster ovary cells, which covalently combined three heterologous RBDs into a single molecule to present potentially broad immunological coverage. Within NVSI-06-09, one RBD is derived from Omicron BA.1 variant, and the other two are artificially designed harboring the key residues from other VOCs and variants of interests (VOIs).
