That’s good! I believe that it can be misleading to assume that because your thymus appears healthy on a CT scan that your immune system is functioning to par. Be sure you have the vitamin C, D, and Zinc in optimal ranges. There are other residual effects from the virus as well such as gut dysbiosis which is cause a number of continuous downstream effects if gone untreated. I did not mean to say any thymus dysfunction is the explanation for long Covid in it’s entirety. There is malabsorption of vitamins, nutrients, and amino acids; gut permeability, organ inflammation, dysfunction in Short Fatty Chain Acid synthesis, neurotransmitter synthesis, and a likely overgrowth of bad bacteria and yeast.
