Post-exposure protection of SARS-CoV-2 lethal infected K18-hACE2 transgenic mice by neutralizing human monoclonal antibody

Here, using the K18-hACE2 transgenic mice model, the authors report the in vivo efficacy of a fully human neutralizing antibody against SARS-CoV-2 and show that when administered before or up to 3 days post infection, treated mice do not exhibit disease symptoms while 80% of control animals succumb...
