Scientists say llamas could help defeat the coronavirus.
The researchers built on previous research from four years ago in which they found that the antibodies from a then nine-month-old llama named Winter were able to neutralize both SARS-CoV-1 and MERS-CoV viruses over six weeks.
Surprisingly, this isn't the first time llamas have been used in antibody research, as The New York Times reports. Llama antibodies have been used in work related to HIV and influenza, where they helped discover promising therapies.
Thanks to the llamas' antibodies' small size, they can connect with different parts of the virus more easily.
"The binding of this antibody to spike is able to prevent attachment and entry, which effectively neutralizes the virus," Daniel Wrapp, Dartmouth Ph.D. candidate and co-author, explained in the statement.
Scientists are hopeful a treatment plan for the newly infected in the form of antibody therapies is particularly promising.
"Vaccines have to be given a month or two before infection to provide protection," McLellan said in the statement. "With antibody therapies, you're directly giving somebody the protective antibodies and so, immediately after treatment, they should be protected."
"The antibodies could also be used to treat somebody who is already sick to lessen the severity of the disease," McLellan added.
"There is still a lot of work to do to try to bring this into the clinic," Xavier Saelens, a molecular virologist at Ghent University in Belgium and co-author, told the Times. "If it works, llama Winter deserves a statue."
