I would like to see the "increasing" body of evidence pointing towards traditional vaccines.
My wife has an autoimmune disease. Most all the evidence points towards gut biome but that shit is super complicated. We have very little research into what our gut biome needs to be.
If you want to continue to believe that vaccines come with no issues, you will find more than enough evidence to support that belief. I'm not here to dissuade you of that. If you are open to considering other possibilities, look into molecular mimicry and immune crossreaction, adjuvants and ASIA syndrome, bystander activation and epitope spreading, MMR and ITP, and the Guillain Barre syndrome studies
