There's a theory in the med community the brain fog, and fatigue parts map to mild heart damage. Possibly undetectable. Where less oxygen is being pumped to the brain, and body. Then with time the heart recovers. With the fog, and fatigue receding. Possibly along with any lung damage affecting oxygen uptake.

Did he get a followup Covid mRNA vaccination after recovery?

A Facebook group called "Survivor Corps" polled 962 COVID-19 long haulers and found 39% said they saw mild to full resolution of their lingering symptoms after they were vaccinated.

46% of people said they remained the same after their shot, 14% said they felt worse.

One long COVID theory is that pieces of the virus may "hide" in the body.

"The vaccine induces robust antibody and T-cell responses that can clear the viral reservoir or remnants that's causing the inflammation, and that would be a permanent solution to long COVID," Iwasaki said.

Another theory is that long COVID is driven by a hyperactive autoimmune response, and the vaccine may reduce those responses.
