I've never harmed myself washing my hands. Vaccines on the other hand have harmed me significantly. Do I need a placebo controlled, double blind clinical trial to know that it was the vaccine that did it? I need it about as much as I need a study to prove unequivocally that getting poked in the eye with a stick hurts every time I do it. I was healthy an hour before, then the vaccination, then over thirty years of struggle until I figured out how to fix the damage of which the pretend authorities couldn't conceive.
If I had researched any other route to health, than the one following the vaccine damage trail, I wouldn't be healthy today. The results are what matter, not willful denial and ignorance.
I don't know what makes your declaration of reality more credible than those who've actually been through the experience, but I suspect that you don't have the slightest idea what you're talking about.
Hygiene and sanitation are what caused the decline in these diseases. Anyone who can read and is not bent on believing the pretend authorities can figure this out for themselves.
I encourage you to keep taking all the vaccines recommended to you and don't forget the ones for your family too. We'll see whose generational health prospers. I don't have any doubt about mine.
