let's imagine this, actually. let's get cybernetic.
if you have a patient that is fucked by this and is having a hard time producing their own antibodies, could you hook them up to a machine that produces antibodies and injects it into their blood?
i'm not imaging a factory, i'm imagining something biological - an antibody-producing culture in a box, and one that ideally generates energy using photosynthesis. so, you'd just hook yourself up to the lamp, or sit by the window and let the beneficial bacteria filter your blood for you - like a symbiotic, external kidney. make it a kidney shaped box...
wait for it.
