Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for millions of infections and hundreds of thousands of deaths globally. There are no widely available licensed therapeutics against SARS-CoV-2, highlighting an urgent need for effective interventions. The virus enters host cells through binding of a receptor binding domain (RBD) within its trimeric spike glycoprotein to human angiotensin-converting enzyme 2. Here, we describe the generation and characterization of a panel of murine monoclonal antibodies (mAbs) specific for the RBD. One mAb, 2B04, neutralized wild type SARS-CoV-2 in vitro with remarkable potency (half-maximal inhibitory concentration of <2 ng/mL). In a novel murine model of SARS-CoV-2 infection, 2B04 protected challenged animals from weight loss, reduced lung viral load, and blocked systemic dissemination. Thus, 2B04 is a promising candidate for an effective antiviral that can be used to prevent SARS-CoV-2 infection.
