Winter (llama)

Winter (born 2015 or 2016) is a female llama who lives on a research farm near Ghent, Belgium and is notable for her role in award-winning research on the SARS-CoV2 virus.[1]

In 2016 Jason McLellan and Daniel Wrapp chose the nine-month-old Winter as the llama they would inject with stabilized spike proteins from SARS-CoV-1 and MERS-CoV viruses, hoping that she would produce antibodies or the smaller nanobodies to further their aim "to isolate a single antibody that could neutralize all coronaviruses".[1]

Camelids, including llamas, produce nanobodies, which are a form of antibody about half the size of human antibodies and are very stable and so can be easily manipulated.[2][3]

When the genetic sequence of SARS-CoV-2 was released in January 2020, scientists worked quickly to test whether any of the antibodies that they had previously isolated against the original SARS-CoV (taken from Winter) could also bind and neutralize SARS-CoV-2. They discovered that one of these nanobodies, which they had characterized using the Argonne National Laboratory's Advanced Photon Source, might be effective against SARS-CoV-2. This nanobody — called VHH72 — is now under development as a treatment for COVID-19. Jason McLellan and Daniel Wrapp received a 2020 Golden Goose Award for this research.[1][2]

As of 2021 Llama Winter lives at LABIOMISTA, the arts and culture park of artist Koen Vanmechelen in Genk, Limburg, Belgium, where people can visit and learn more about her.[4]
