I’m here because I also found out I have low iron after Pfizer vaccine. I had a small allergic reaction day of the first shot. Two days later I started experiencing shortness of breath and couldn’t even do household chores or walk my dog. They thought it was asthma and treated it as such but nothing improved. Then the fatigue set in. I couldn’t get a doctor to take me seriously for 2 months. I started iron supplements on my own and started to see some improvement in the shortness of breath. Finally found a doc willing to investigate. They ran blood work and iron is low. I initially reported reaction to VAERS before knowing what was wrong. I wanted to update but VAERS isn’t responding with a key so I can document. So not surprised there are no documented cases in VAERS. They don’t seem to want people to report.
