Drug intelligence / Profile preview
Nuvaxovid (NVX-CoV2705) is a recombinant protein nanoparticle vaccine developed by Novavax in partnership with Sanofi, specifically engineered to target the SARS-CoV-2 Omicron JN.1 variant. The vaccine consists of 5 mcg of purified recombinant spike protein and is formulated with 50 mcg of the Matrix-M adjuvant, a saponin-based component that enhances the immune response by stimulating antigen-presenting cells. Unlike mRNA-based COVID-19 vaccines, Nuvaxovid uses a traditional protein subunit platform. Sanofi leads the commercialization and regulatory efforts for this formulation, which received FDA Emergency Use Authorization in August 2024 and full Biologics License Application (BLA) approval in May 2025 for use in individuals aged 12 years and older.
