In regards to vaccine injuries.... inflammation is the most likely
cause of your problem. In some people a cytokine storm is the result of vaccines. The European vaccines had squalene in them which is very allergenic. Some of the US vaccines also, (European ones were imported after about Nov here because the non-squalene vaccines were in very short supply.)

The best explanation about vaccine reactions is on YouTube by Dr. Blaylock MD who has researched this problem at great length.

This is a link to part 1 of 4 parts of this interview by Dr. Mercola of Dr. Blaylock. Dr. Blaylock also has his own website.
Part 2 is the major explanation of "cytokine storms" some people get from vaccines. So in essence your treatment using prednisone is probably far more accurately targeting your current problem.

The formula being asked about here is for people who may be deficient in B12, or B1, or who have oxidative damage to the mitochondria. The lipoic acid is mostly for the oxidative damage.
One thing NOT in that mixture is acetyl carnitine, which is often included in formulas for mitochondrial support (helping the mitochondria produce energy better.) D-ribose also helps at this target.

Inflammatory damage to neurons also may be supported by Vit C, and antioxidants. Grapeseed extract is good for this, about 200mg a day, and affordable. Eating antioxidant rich foods, like blueberries, strawberries, and brightly colored veggies, is also helpful.

I personally believe that vaccine induced injury is far more common than realized. So please watch Dr. Blaylock. He is really interesting and has other videos besides that 4 parter on YouTube. He has a newsletter you can sign up for. One poster here posted his recommendation for l-theanine for neuropathy, and I've been using that at 300mg at night since August, with great success. So check out this link:
