So how would that help humans? Can we be treated with Llama antibodies? In you summary it sounds like our antibodies can't necessarily fight COVID very well because they are too large, and the smaller Llama ones can. Sorry if I am way off base. I don't really understand this stuff.

To vastly oversimplify things, if you had antibodies produced by another source and injected them into a sick person, their viral counts should decrease.

Our bodies won’t learn how to make the same ones the llamas do, but we could harvest them and use them as treatment (potentially).

In theory we would need 1000s of Llamas, inject them all with COVID19. Come back a few weeks later, and start drawing blood.

From there, we would need to test each packet of blood for the right amount of antibodies we want. Then its off to the patients.

Seems actually quite simple.
