- Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic is continuing to disrupt personal lives, global healthcare systems, and economies. Hence, there is an urgent need for a vaccine that prevents viral infection, transmission, and disease. Here, we present a two-component protein-based nanoparticle vaccine that displays multiple copies of the SARS-CoV-2 spike protein. Immunization studies show that this vaccine induces potent neutralizing antibody responses in mice, rabbits, and cynomolgus macaques. The vaccine-induced immunity protects macaques against a high-dose challenge, resulting in strongly reduced viral infection and replication in the upper and lower airways. These nanoparticles are a promising vaccine candidate to curtail the SARS-CoV-2 pandemic., Competing Interests: Declaration of interests N.P.K. is a co-founder, shareholder, and chair of the scientific advisory board of Icosavax. The remaining authors declare no competing interests. Amsterdam UMC has filed a patent application concerning the SARS-CoV-2 mAbs used here (Brouwer et al., 2020). N.P.K. has a nonprovisional US patent (no. 14/930,792) related to I53-50 (Bale et al., 2016)., (Copyright © 2021 The Authors. Published by Elsevier Inc. All rights reserved.)
