Doesn't mean you cannot carry it on something though. But everything is risk management

You can still be re-infected, it just won't take hold. For the immune system to tackle it, the virus has to be in the blood stream, ie you've been re-infected.
I wonder if in certain circumstances, it can infect tissue almost directly, without having to travel too far in the blood stream. Nasal and lung tissue is fairly accessible in a direct way. To that extent, it is almost external tissue like skin, without the barrier the skin has of dead skin tissue.
