Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	Organization and Business Novavax, Inc. (“Novavax,” and together with its wholly owned subsidiaries, the “Company”) is tackling global health challenges through scientific innovation that seeks to maximize its deep scientific expertise in vaccines and cutting-edge technology platform. The differentiated platform features the Company’s recombinant protein-based nanoparticle technology and its unique Matrix-M® adjuvant. The Company’s corporate growth strategy seeks to optimize its existing partnerships and expand access to its proven technology platform via research and development (“R&D”) innovation, organic portfolio expansion in infectious disease and beyond, and forging new partnerships and collaborations. The Company’s three strategic priorities are: focusing on its partnership with Sanofi Pasteur Inc. ("Sanofi”) announced in May 2024, leveraging its technology platform and pipeline to forge additional partnerships, and advancing its proven technology platform and early-stage pipeline. The Company’s corporate growth strategy is supported by a lean and focused operating model. Novavax’s prototype COVID-19 vaccine (“NVX-CoV2373,” or “prototype vaccine”), the Company’s XBB COVID-19 vaccine (“NVX-CoV2601”), and the Company’s Nuvaxovid™ JN.1 COVID-19 vaccine (“NVX-CoV2705” or “updated vaccine”) are collectively referred to as the Company’s “COVID-19 vaccine.” Local regulatory authorities have also specified nomenclature for the labeling of NVX-CoV2373, NVX-CoV2601 and NVX-CoV2705 within their territories (e.g., “Novavax COVID-19 Vaccine, Adjuvanted”, “Novavax COVID-19, Adjuvanted (2023-2024 or 2024-2025 Formula),” respectively, for the U.S., and “Nuvaxovid™” for ex-U.S. territories). The Company’s partner, Serum Institute of India Pvt. Ltd. (“SII”), markets Novavax’s COVID-19 vaccine as “Covovax™.” Currently, the Company significantly depends on its supply agreement with SII and its subsidiary, Serum Life Sciences Limited (“SLS” and together with SII, “Serum”), for co-formulation, filling, and finishing.
