Worth noting that if I understand the mode of action of these proteins and have correctly read the tested dosages in the papers out thus far, a treatment would be more along the lines of the antibody immunotherapy infusions that people get for some types of cancer than a pill for a systemic effect, with localized versions like a nebulizer applied to things like a strong lung infection. And it's likely to cause a temporary inflammatory effect as lots of cells (including ones with no viral infection or latent viruses that everyone and I mean everyone has) blow up. You probably don't take this for a cold.
