It is an entirely synthetic vaccine. The subunit vaccine antigen is precisely designed based on the structure of the targeting S-RBD and HR protein of XBB.1.5 and BA.5 subvariants, and can self-assemble into stable trimeric protein particles. Study revealed that the vaccine induced high titers of neutralizing antibodies against Omicron XBB.1.5, BQ.1, BF.7, BA.5, BA.2.75 and other subvariants, suggesting that it is a broad-spectrum COVID-19 vaccine against multiple prevalent subvariants at home and abroad such as XBB.1.5, BQ.1, BF.7 and BA.5. At present, WestVac Biopharma is proactively engaged with the national authorities, and striving to meet the national approval requirements as soon as possible for the trivalent recombinant protein vaccine.The mission is to use WestVac BioPharma's power to aid in the fight against new variants of novel coronavirus!
