Abstract: Infectious diseases remain a problem throughout the world. The outbreak of sudden acute respiratory syndrome coronavirus 2 (SARS-Co V-2) has infected more than 640 million people worldwide. SARS-Co V-2 causes the disease COVID-19. Mutations in the SARS-CoV-2 S spike protein enable SARS-CoV-2 variants to escape neutralizing monoclonal antibodies produced from previous infection with SARS-CoV2 or by vaccination. The present invention provides antibodies that bind to the SARS-Co V-2 Spike (S) protein. The invention further relates to pharmaceutical compositions, immunotherapeutic compositions, and methods using the aforementioned antibodies that bind to the SARS-CoV-2 Spike (S) protein.
