What % of people got long covid who were vaccinated VS those who weren't?

Interesting to see if any research has been done on this subject.

As the other user pointed out, long Covid is incredibly problematic because until rather recently, every researcher used their own definition of the condition, that's why you would get one study saying 3% have it, and another saying 30% have it. On top of that, almost all studies I've seen have used self-assessment by patients of whether they think they have it, which of course has a ton of issues as you would imagine.
