I have only anecdotal evidence. My brother got Covid and after he recovered he would black out from walking briskly up a single flight of stairs from sudden lack of oxygen (O2 meter on his finger showed this as well). He was otherwise fine and could breathe easily, it just didn't oxygenate his blood well. He got the vaccine and that symptom just disappeared.
