Just anecdotally I can only speak for myself but I have stayed clear of vaccines for 29 years after the military used experimental vaccines on me and I never doubted or regretted my decision. I instead focus on keeping my innate and adaptive immune systems incredibly strong. This requires discipline and dedication to a strict diet and moderate exercise and is why I suspect that many people are opposed to this way of life. There are a million rabbit hole arguments for and against what I am doing but I am happy with the path I am on.
