Coviccine® Bivalent-- Recombinant COVID-19 Bivalent (XBB+Prototype) Protein Vaccine (Sf9 Cell)

The Recombinant COVID-19 Bivalent (XBB+Prototype) Protein Vaccine (Sf9 Cell) is an upgraded version of Coviccine® --Recombinant COVID-19 Vaccine (Sf9 cell) developed by WestVac Biopharma. Studies have shown that the vaccine induced high titers of neutralizing antibodies against multiple subvariants, including XBB.1.5, XBB1.16, XBB1.9.1, XBB.2.3, BA.5, BF.7, BQ.1^[1], indicating that the vaccine is a universal COVID-19 vaccine effective against multiple strains, especially with a particularly significant increase in neutralizing antibodies against XBB series variants.

Recombinant COVID-19 Trivalent (XBB+BA.5+Delta) Trimeric Protein Vaccine (Sf9 Cell)

Taking advantage of the rapid response of the internationally advanced insect cell expression platform in recombinant protein vaccine production, WestVac Biopharma and its subsidiary company called WestVac Biopharma(Guangzhou) has constructed the vector for the Recombinant COVID-19 Trivalent (XBB+BA.5+Delta) Protein Vaccine (Sf9 Cell), and produced trivalent recombinant protein vaccines of high purity and high quality for human use. The subunit vaccine antigen is precisely designed based on the structure of the targeting S-RBD and HR proteins of the COVID-19 subvariants XBB and BA.5, and can self-assemble into stable trimeric protein particles. Studies have shown that the vaccine induced high titers of neutralizing antibodies against multiple subvariants, including Omicron XBB.1.5, XBB1.16, XBB1.9.1, XBB.2.3, BA.5, BF.7, BQ.1, BA.2.75, indicating that it is a broad-spectrum COVID-19 vaccine against multiple prevalent subvariants at home and abroad^[1].
