derived from a llama named fifi has shown significant potential in early trials. it is a treatment made of nano bodies, small versions of antibodies which llamas produce naturally in response to infection. once the therapy has been tested in humans, it could be given as a nasal spray, to treat and even prevent early infection. this was thought to be just something of an evolutionary quirk when it was first discovered that llamas, camels, alpacas and strangely sharks have the special nano bodies, they produce antibodies that are slightly different from ours, much smaller and simpler molecules. ours are these quite cumbersome complicated molecules. that was discovered a few decades ago but with these researchers hope to have done is investigate theirs as a possible covid therapy, and immune therapy using these nano bodies because they re so simple they are interesting to molecular biologist to reengineer and
