Anyone know the situation there?

From what I read these are cases where an infection did take hold and they had symptoms. However, the symptoms where reportedly a lot milder and the infection dealt with faster, i.e although they were reinfected the immune system still managed to deal with it quicker.
I don't fully understand it but I think the immune system can do two things: stop an infection before it even takes, fight it after it does.
The other thing though is sometimes having had an infection or even having had a vaccine you can randomly simply not develop antibodies against it. It's not common but it does happen.
