> In addition, 1/4th of human DRG neurons express mRNA for SARS-CoV-2–associated receptors and deploy ACE2 protein. Thus, virus or spike protein fragments may attach to them, promoting formation of antibodies that can also target adjacent neural epitopes. The paper briefly mentions this, but is there a biological difference in how the body responds to SARS-CoV-2 spike proteins from COVID infection versus vaccine-induced production of these proteins? I feel like this question is often labelled as "anti-vaxx" but it's a valid concern. It could explain some of the rare neurological side effects some people experience from the vaccines. It seems to boil down to some immune response, so it may make sense that vaccine-induced protein generation from within the body produces a less intrusive immune response, but this is just a layman's understanding.
