Novavax COVID-19 Vaccine (NVX-CoV2373) Description
Novavax COVID-19 vaccine (NVX-CoV2373) (Covovax) is a prefusion protein coronavirus vaccine candidate made using Novavax’s proprietary nanoparticle technology, Matrix-M, an adjuvant to enhance immune responses and stimulate high levels of neutralizing antibodies.
Novavax Inc. s NVX-CoV2373 vaccine candidate creates an engineered baculovirus containing a gene for a modified SARS-CoV-2 spike protein. The baculovirus then infects a culture of Sf9 moth cells, which create the spike protein and display it on their cell membranes. The spike proteins are then harvested and assembled onto a synthetic lipid nanoparticle about 50 nanometers across, each displaying up to 14 spike proteins.
NVX-CoV2373 COVID-19 Vaccine Description
NVX-CoV2373 is a prefusion protein coronavirus vaccine candidate made using Novavax’s proprietary nanoparticle technology, Matrix-M, an adjuvant to enhance immune responses and stimulate high levels of neutralizing antibodies.
Novavax’s patented saponin-based 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 virus.
Novavax identified the recombinant nanoparticle NVX‑CoV2373 vaccine as its lead COVID-19 candidate following pre-clinical testing that demonstrated high immunogenicity and high levels of neutralizing antibodies.
