There has been three or four studies, and they all show long covid risk going up with repeat infections. The damage from infections accumulates with each infection, and Iirc we have about a 4% chance of developing long covid after every infection. Essentially the same chance as rolling snake eyes on a pair of dice.
The problem now is the lack of covid testing and the wide range of symptoms and their severity. People chalk it up to aging or "sometimes bodies just do that". It's hard to definitively track the risk to know whether it's improving or not.
With how infectious the virus is, and how much of the body it can attack, and how rapidly it's mutating (approx 4x faster than the flu), the protection we get from a vaccine or exposure doesn't last long enough. Getting covid 2-3 times a year if you drop all precautions seems like a really, really bad idea.
