I'm so glad I found this chat. In an office if 10 allied hospital workers, 3 of whom have ongoing iron def issues, 3 who had covid. All of us had the j&j vaccine and now all of us have experienced fatigue and dissy spells which led us to do iron tests.. All of tested low fe and ferritin.. Even the people who have never had an iron issue are presenting with ferritin of 10 to 15 microgram/l
