I'm glad to see these findings get serious attention by researchers. It was really frustrating getting dismissed by my local physician when sharing symptoms like sugar sensitivity, fatigue, and focus issues. It was like being perpetually tipsy for months. It was a big shock as a knowledge worker to have to relearn how focus.
I hope they further study vaccines as well. In my anecdotal case my long covid symptoms resumed, along with additional symptoms like body bruising / bone pain for several weeks. There may be classes of healthy adults that react differently than expected and we can learn how to improve from the evidence.
