Sounds like they have legal advice to say they are not anti-vaccine.
I’ve lived a very long time and I’ve never had a vaccine of any kind. So, I didn’t even think about getting the covid one. I’ve never been really sick. Had 4 kids. I guess maybe I can be called a naturalist. I leaned the old herbal remedies from great grand, grandmother and mother. I have added a few vitamines but that is all. I have old age bone pains from time to time, but those are not too bad. I use Vinegar inside and out for bone aches, and exercise helps too. No covid yet. Not isolated and go where ever I want to. Nobody has challenged me yet about masks or vaccines. Don’t plan to.
