The discovery could offer an initial step towards developing a fully-human antibody to treat or prevent the disease...
The neutralising antibody "has potential to alter the course of infection in the infected host..."
Dr Frank Grosveld, the study's other co-lead author, said the discovery provided "a strong foundation for additional research to characterise this antibody and begin development as a potential COVID-19 treatment".
Pfizer Inc and BioNTech SE said on Tuesday they have begun delivering doses of their experimental coronavirus vaccines for initial human testing in the United States.
The U.S. drugmaker and German partner said if the vaccine proves to be safe and effective in trials, it could potentially be ready for wide U.S. distribution by the end of the year, shaving several years off the typical vaccine development timeline.
