Scientists were inspired by antibodies produced by this llama, named Winter, to develop their antibody against SARS-CoV-2. Winter is four years old and still living on a farm in the Belgian countryside operated by Ghent University’s Vlaams Institute for Biotechnology. Photo credit: Tim Coppens.

Researchers linked two copies of a special kind of produced by llamas to create a new antibody that binds tightly to the spike protein on the coronavirus that causes COVID-19. This spike protein allows the virus to break into host cells. Initial tests indicate that the antibody blocks viruses that display this spike protein from infecting cells in culture.

The hunt for an effective treatment for COVID-19 has led one team of researchers to find an improbable ally for their work: a llama name...
