> So when you get a booster (or a breakthrough infection) your immune system kicks into gear again but now it produces a broader range of antibodies.

Would/could it not also be the case for exposure to the virus that doesn't result in a breakthrough infection i.e. the body detects it and fights it off successfully? (I daresay you didn't mean to imply that, just checking.)

I would assume so but it probably depends on the "level" of exposure and such.
