I am a nurse, have no history of anemia and had normal iron/ferritin labs prior to the Pfizer vaccine in June/ July. After my second dose in July, I was extremely tired all the time, I followed up with my healthcare provider who immediately referred me to hematology. My ferritin was 4 and my iron saturation was less than 9%. After two rounds of feraheme, I’m beginning to feel normal again. I 100 % believe it was related to the vaccine since they could find no cause for it and it’s interesting to find others that suddenly have an iron deficiency after the vaccine. I am thankful that I found this site and I will also add that I am extremely reluctant to get the booster knowing that so many of us have had this issue.
