As long as the resistance isn't 100%, aren't the options 1 and 3 basically the same from an individual's point of view? That is, can't you rephrase "You are naturally resistant" as "You don't have increased risk", as long as you talk to individuals rather than to societies? Like you explain, what people can do with this kind of information individually is get health advice that applies to them personally.

Edit: I think I should explicate that I think people take a doctor's opinion more seriously if they can see it's tailored to them more.
