Three years and three months ago I had the Moderna booster. Immediately I was unstable walking, which got worse as days went on. I kept waiting for it to go away, used a walker sometimes, and was very fatigued. A year and a couple months later I saw a neurologist and had a nerve conducive test. He said it appeared that I had guillaine barre syndrome. Nothing was recommended or prescribed. I continued with physical therapy and rest thinking my life was about to end this way, I had retired just five months before the booster. Then in this last July, I read about nattokinase, and began taking it twice daily. In just a couple weeks I noticed a difference! Now it is six months later and I feel 80-85 percent improved! Am so excited to think I have some life left.
