I had my first vaccination in March 2021 and in less than one week I tested positive for Covid. While I was ill, my blood pressure dropped dramatically (bordering on dangerously low) and I could not stand up without feeling as if I would pass out. It wasn't until approximately two months later that I had my iron checked and discovered that I was suffering from low iron and low ferritin. I had just assumed that the severe drop in my BP and ongoing shortness of breath were the result of Covid but now I wonder whether all of this was actually caused by the iron depletion as a side effect of the vaccination instead. The many accounts from people who do not indicate that they had Covid seem to point to the vaccination. As mentioned, I had one shot (Moderna) followed by Covid and an infusion of monoclonal antibodies (Regeneron). I did not get my second vaccination and will not get a booster. I believe, and evidence seems to indicate, that natural antibodies are at the very least, as good as the vaccine, are longer-lasting and more effective. And all these months later I am still waiting for my iron/ferritin levels to be where they belong.
