About the candidate

NVX-CoV2373 is a protein-based vaccine targeting SARS-CoV-2, the virus that causes COVID-19. Recombinant technology is used to create vaccine nanoparticles, which are then mixed with Matrix-M™ adjuvant to create the ready-to-use NVX-CoV2373 vaccine1. NVX-CoV2373 in the United States has received Emergency Use Authorization. For Global authorizations, please refer to the global vaccine authorization/approval map.
