Long Covid: Most symptoms resolve within a year after mild infection, study (bmj.com)

I can provide my anecdotal evidence. Got COVID and the vaccine at around the same time in April 2021. Had a lot of random chest pains and fatigue for a while. Was finally able to work out again after 6 months, though lost a lot of progress. Now, 1.5 years later, I have finally surpassed where I was prior to getting sick, and feel no ill effects.
