” Llamas and other camelids fight off pathogens like viruses with tiny antibodies called single-domain antibodies or “nanobodies.” The UCSF team used protein engineering to make a synthetic nanobody that prevents the spike protein on the surface of SARS-CoV-2, the virus that causes COVID-19, from binding to healthy cells and infecting them.”
Not yet in human testing.

“Nanobodies are smaller and more stable types of antibodies taken from the immune systems of camelids—which include camels, llamas and alpacas. Nanobodies could be more effective at fighting the disease because their tiny size gives them the ability to fit into spaces on viral proteins that regular antibodies have a hard time penetrating.
“The idea is that nanobodies are small enough to access small pockets on SARS-CoV-2’s spike proteins, which is the part of the virus that attaches to host cells. “
