...herpes sufferers, or diabetics feel better (or, even worse)? That which didn't kill *me* left me brain-damaged and somewhat immobile. I suggest that "That which doesn't kill you makes you HURT" may be more accurate in real life; I'm much less strong than I was before 'that' didn't quite 'kill me', but it still hurts every day.
I agree, however, with the point I believe you were making about immuno-epidemiology.....
How's this? "That which doesn't kill you leaves you.....irritable"

(edit: 'leaves' was 'makes', altered for clarity)
