I don't get mosquito bites reactions anymore, but I did as a kid. My wife and kids get them bad. Recently I noticed getting bit and still not getting a reaction. It's weird, I seem to have developed an immunity.
I looked it up, and it seems to happen at least anecdotally https://outdoors.stackexchange.com/questions/4310/is-it-possible-to-develop-immunity-against-mosquitos
