Abstract

Despite effective vaccines against SARS-CoV-2, therapeutic options such as anti-virals and neutralizing antibodies are critical in treating disease, especially given the breakthrough infections of emerging VOCs. Here, Peng et al. generate two potent monoclonal antibodies and a bispecific antibody with two antigenrecognition variable regions targeting SARS-CoV-2 spike, provide CryoEM structures and show in vitro and in vivo efficacy of a humanized antibody against wildtype virus and delta variant.
