I am non-vaxxed... I've been taking a maintenance dose of chlorine dioxide since Jan 2020. Haven't had as much as a sniffle since. I used to be plagued by any stomach virus that was floating around and not one of those either. It's actually a gas (dissolved in water) so an activated solution degrades rapidly (why they don't sell it activated). Take the leap! I've become quite the kitchen chemist. I also mix my own vit C and hyaluronic acid (facial) for pennies on the dollar they charge for a tiny bottle. I just happened to come across an article about CD and covid back then and decided to try it out as a prophylactic. You'll need a digital kitchen scale,$20. Amazing stuff! I bought crystals from Amazon and mixed my own along with the citric acid to activate (already had some food grade CA we use in the pool). It was originally used to purify water for drinking.
