My brother has this permanently, though whether a delayed reaction to the booster or from when he got COVID itself (a relatively mild case) not long after, there's no way to know.
It has been a major detriment to his day to day life though. Any physically involved hobbies are impossible; just walking up a flight or two of stairs now leaves him completely winded for several minutes, as his heart rate also takes longer to come back to resting than before.
Would not recommend.
