You’re basically right, we have no idea how to do this - we can help the immune system remember new things (ie we’ve started teaching it how to attack cancers that it has been ignoring) but when the body wants to go at something, the only way we’ve been able to get it to sort it’s shit out is to wipe out all the agents of the adaptive immune system and implant a new one (give someone a bone marrow transplant). This has resulted in cures for patients with MS, but is really risky and doesn’t scale.
