You are the first to say they used it. I think others I have shared it with don’t want to know.
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.)
