It is how immunisation works. Gives you a lower rate if a virus. Your body fights it off. But when it shows up again it fights it off.Sorry to be thick, so taking Hill as an example who's having a pretty rough time and quite probably has this. In a couple of weeks he's over it and will have antibodies protecting him - any close contact with family/friends, he'll pass his immunity onto them, rather than giving them the lurgy?
Hills body will have fought it off. So his body will be ready for it next time. So he shouldn't catch it again. But he won't be contagious.
That is the reasoning of letting enough people catch it so hospitals can cope but we become immune to it over time. Most don't have much if a problem fighting it off.
They say an 80% immunisation is the lowest point where it would struggle to survive. Personally I'd see it above this. But I am not an expert.
