Coronavirus: Alpacas provide new hope for a COVID-19 cure

Alpacas join search for COVID-19 cure

Australian researchers are infecting alpacas ( Vicugna pacos) with SARS-CoV-2, in search of treatments against the virus. They are attempting to extract and purify antibodies produced by the animals, which could later be injected or inhaled by patients to prevent or cure COVID-19. Alpacas and other camelids produce two types of antibodies — one similar to human antibodies, and a dramatically smaller version called a nanobody. The nanobody’s small size makes it more effective at getting around the virus’s defences. “They are really special. They are really small, very stable, and extremely sticky to the spike protein,” says infectious-disease researcher Wai-Hong Tham.
