I am by no way a doctor and my dd has always cultured staph since 3 mo. But if i were in your shoes, i would try to eradicate it, i mean any bug can potentially cause lung damage, so i would give it a shot. I don't know what the protocol is for this, but i would think that one long course of antibiotics (if that is what needed) would not cause the sensitivities to disappear.At least not in ly experience.
