For what it’s worth, the first time anecdotally seems to be worse a lot of the time.
The vaccines produce very specific antibodies which do help, but when you get a real infection your body is able to make all sorts of other antibodies as it’s not only based off the very specific vaccine output.
So the 2nd time you get it, you now got the various vaccine antibodies / knowledge, and the more smorgasbord of antibodies and knowledge from the actual virus.
Not to say it still can’t be bad, but there’s a little hope that it might not be as bad.
