MRNA-delivered neutralizing antibodies confer protection against SARS-CoV-2 in animal models.

ABSTRACT: Monoclonal antibodies represent potent biological countermeasures against a wide range of human diseases; however, their clinical application and widespread use are limited by the high cost and complexity of antibody production and manufacturing. The mRNA-lipid nanoparticle (mRNA-LNP) platform offers a versatile strategy for vaccine development and protein-replacement therapies. Since the COVID-19 pandemic, a number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-neutralizing antibodies have been identified, with several granted emergency use authorization for patients. Here, we report the design and generation of mRNA-LNPs encoding two SARS-CoV-2-neutralizing antibodies, 76E1 and LY1404, which, respectively, target the spike protein's fusion peptide (FP) and receptor-bindi
