Novavax COVID-19 Vaccine (Nuvaxovid™) Description 2022

Novavax COVID-19 vaccine (Nuvaxovid™, CovoVax™, NVX-CoV2373)  (SARS-CoV-2 rS [Recombinant, adjuvanted)) is a protein-based vaccine candidate engineered from the genetic sequence of the first strain of the SARS-CoV-2 beta coronavirus. The COVID-19 vaccine was created using Novavax's proprietary nanoparticle technology, Matrix-M, an adjuvant to enhance immune responses and stimulate high levels of neutralizing antibodies.

Novavax Inc.'s vaccine candidates 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.

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.

On Aug. 4, 2020, Novavax announced the Phase 1 data from its Phase 1/2 clinical trial found the recombinant COVID-19 vaccine candidate adjuvanted with Matrix-M was generally well-tolerated and elicited robust antibody responses numerically superior to that seen in human convalescent sera. A Phase 3, Randomized, Stratified, Observer-Blind, Placebo-Controlled Study to Evaluate the Efficacy, Safety, and Immunogenicity of mRNA-1273 SARS-CoV-2 Vaccine in Adults Aged 18 Years and Older was last updated on Oct. 28, 2020. Cellular immune responses were measured in a subset of participants, and NVX‑CoV2373 induced antigen-specific polyfunctional CD4+ T cell responses with a strong bias toward the Th1 phenotype (IFN-g, IL-2, and TNF-a).

On Jan. 28, 2021, NVX‑CoV2373 became the first protein-based vaccine candidate to demonstrate clinical efficacy against the original strain of COVID-19 and both of the rapidly emerging variants in the United Kingdom (U.K.) and South Africa. In addition, the Company announced the vaccine's efficacy of 96.4% against mild, moderate, and severe disease caused by the original COVID-19 strain in a pivotal Phase 3 trial in the U.K. 

On Dec. 17, 2021, the World Health Organization (WHO) granted Emergency Use Listing for the NVX‑CoV2373 vaccine manufactured and marketed by Serum Institute of India Pvt. Ltd. (SII) named CovoVax. Novavax's COVID-19 vaccine Nuvaxovid was endorsed by the European Medicines Agency, and European Commission granted conditional marketing authorization on Dec. 20, 2021 - E.U. study number: EudraCT number, 2020-004123-16.

Then, the NEJM published a paper on Feb 10, 2022, concluding a phase 3 clinical trial: NVX-CoV2373 was safe and effective for preventing Covid-19. Most breakthrough cases were caused by contemporary variant strains. A pivotal Phase 3 clinical trial conducted in the UK published on Feb. 28, 2022, found a high level of efficacy for NVX-CoV2373 was maintained over 6-months of surveillance. Additionally, the analysis showed vaccine efficacy of 82.5% (95% CI: 75.0, 87.7) in protection against all COVID-19 infections, both symptomatic and asymptomatic, as measured by PCR+ or anti-N seroconversion.

A non-peer-reviewed head-to-head comparison published on March 21, 2022, shows that the mRNA COVID-19 vaccines made by Pfizer and Moderna outperform those produced by Jansen (Johnson & Johnson) and Novavax. The data also provide a finely detailed picture of each vaccine's immune protection.
