Novavax COVID-19 Vaccine (Nuvaxovid, CovoVax, NVX-CoV2373) 2023
Novavax COVID-19 vaccine (Nuvaxovid™, CovoVax™, NVX-CoV2373) is a protein-based vaccine engineered from the genetic sequence of the first strain of the SARS-CoV-2 beta coronavirus. The COVID-19 (SARS-CoV-2 rS [Recombinant, adjuvanted)) the vaccine was created using Novavax's proprietary nanoparticle technology, Matrix-M™, an adjuvant to enhance immune responses and stimulate high levels of neutralizing antibodies. Matrix-M adjuvant has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes, boosting immune response and helping an immunized person make antibodies against the coronavirus.
Novavax Inc.'s vaccines are genetically engineered using three-dimensional nanostructures of recombinant proteins critical to disease pathogenesis. The COVID-19 vaccine creates an engineered baculovirus containing a modified coronavirus spike protein gene. The baculovirus then infects a culture of Sf9 moth cells, which generate the spike protein and display it on their cell membranes. Next, the spike proteins are harvested and assembled onto a synthetic lipid nanoparticle about 50 nanometers across, each displaying up to 14 spike proteins.
On Dec. 17, 2021, the World Health Organization (WHO) granted Emergency Use Listing for Novavax's NVX‑CoV2373 vaccine manufactured and marketed by Serum Institute of India Pvt. Ltd.
