Question though- I went out to a very busy place for Halloween. The next morning, I took a small amount of horse paste, some zinc and some vitamin d3 as I normally do when I’ve been around tons of ppl. Started feeling sick two days later. Fever, headache and exhaustion. Tested positive for covid. Took ivermectin pills from the doctor, and I got better pretty fast. Why didn’t the paste prevent me from getting symptoms and testing positive in the first place? I have been wondering that. I might not have taken enough, idk
