I am updating my original post. I'm feeling much better, finally. I've been supplementing with Vitamin D3 and flushing my system with water. I will never...EVER...take that shot again, nor will I allow my children to do so. My body is equipped with a system to handle illness, and I'll be using it. When/If I get the flu, I'll support that immune system naturally. Big pharma can kick rocks. I'm done with that mess.
