A couple thoughts:
1. Find a sympathetic (usually holistic or homeopathic vet) who understands your goals and will work with you. That might even be long distance, which works well with homeopathy. You've got chronic disease at play here, and that's rarely DIY. Homeopathy shines in curing chronic disease, and I tell you how to choose a good vet on my https://vitalanimal.com/recommended-resources/ page.
2. It sounds like you've got a pretty developed sense of "germophobia" working in your mind. No greater health comes from sheltering anyone, dog, cat, child, adult, from the rich world of microbes that we actually depend on to be healthy. Listen to some of the Vital Animal Podcast episodes with Julie Anne Lee (leaky gut, skin microbiome coming soon) and tune in to Zach Bush, MD for the reality that abundant diverse populations of bacteria and viruses in and on us all have been the key to our survival. It's part of how Mother Nature designed us all. The dog who licked her nose did her a favor.
It's not that your dog depends on vaccination to somehow become "complete" and have a functional immune system. Far from it.
