” Based on positive results in preclinical studies reported today, potently neutralizing antibodies identified by researchers at Vanderbilt University Medical Center (VUMC) are showing promise as a potential therapy for preventing and treating COVID-19.

They were two of the earliest confirmed cases of COVID-19 in North America. “

Monoclonal antibodies will be VERY expensive as a treatment.
