Why llamas could be key in the fight against Covid-19

The solution to Covid-19 may have been staring us in the face this whole time, lazily chewing on a carrot. All we need, it seems, is llamas.

A study published last week in the journal Cell found that antibodies in llamas’ blood could offer a defence against coronavirus. In addition to larger antibodies like ours, llamas have small ones that can sneak into spaces on viral proteins that are too tiny for human antibodies, helping them to fend off the threat. The hope is that the llama antibodies could help protect humans who have not been infected.

International researchers owe their findings to a llama named Winter, a four-year-old resident of Belgium. Her antibodies had already proven themselves able to fight Sars and Mers, leading researchers to speculate that they could work against the virus behind Covid-19 – and indeed, in cell cultures at least, they were effective against it. Researchers are now working towards clinical trials. "If it works, llama Winter deserves a statue," Dr Xavier Saelens, a Ghent University virologist and study author, told the New York Times.

To any llama aficionado, this news should come as no surprise. The animals have developed a reputation for healing. Llama antibodies have been a fixture in the fight against disease for years, with researchers investigating their potency against HIV and other viruses.

And their soothing powers go beyond the microscopic. Llamas have become exam-season fixtures at a number of top US colleges. George Caldwell, who raises llamas in Sonora, California, brings his trusted associates to the University of California, Berkeley, UC Davis, Stanford, and other northern California universities to help students overcome end-of-term anxiety. "When you're around a llama, you become very calm and at peace," one Berkeley student said at a campus event last year.

Natural allies

Humans and llamas are natural allies, said Caldwell, though too few realise it. "People see the llamas, they all light up," he said. "Llamas just have that ability – it's programmed right into us." Their hair can be used to make clothing, their manure benefits crops, and as Winter's antibodies reaffirm, "even their blood can help us". And they are known as pack animals, a skill currently serving them well in Wales, where these hairy essential workers are delivering groceries.

“Everything about these guys – you’d think that they’d be the most valued creature in the world,” Caldwell said. His goal is to spread the word about their gifts: “Llamas are the real unicorns.”

Caldwell has discussed collecting antibodies with his vet, but it is not an easy process, he says, especially for an older person: some llamas are less than eager to become blood donors, and they can be “ruffians” when the situation calls for it. – Guardian
