I checked my two Pfizer batches and they were benign - excepting a list of possible relatively common side effects that occur in most prescription clinical surveys. I listed a side effect on VAERS - abnormal low blood iron, ferritin readings. I noted that my PCP and my Hematologist declined to endorse my theory but I wanted to put the information on record. In time those anomalies have returned to normal for me. (ferritin operates in the body as an mRNA agent which made me suspicious.)
FYI - low ferritin can also be as a result of low Vitamin B12. I know this because my daughter was having issues in college passing out. Turns out she had a few things going on: multiple allergies and heavy monthly cycles were draining her iron levels. Apparently when iron drops below a certain level the body starts using the B12 as a substitute which drops the ferritin levels dramatically to the point that o2 transport is impacted resulting in passing out. rapid onset, slow recovery. Took 4 doctors and multiple episodes before we were finally able to get an accurate diagnosis. B12 shots for a few months short term while taking iron supplements to build her stores back up got her stable. Still don’t know what all the allergies are because she’s too sensitive for a proper panel test.
