I have no history of anemia, and no underlying health conditions. My labs were totally normal prior to taking Pfizer vaccine. On May 5 I had my annual exam with PCP. Normal hemoglobin, normal hematocrit, normal RBC. On May 7 I got first shot of Pfizer, and second shot on June 2. No major side effects immediately after vaccine. During the summer I started feeling weaker and weaker, could not handle even a 30 min walk, shortness of breath, palpitations, body aches, chest pains, dizziness (near faint spells). Cardiology tests were all normal. Pulmonology tests were all normal. Inflammatory markers were all normal. I am normal weight, eat healthy and take vitamins. Yet I was feeling progressively worse. I did CBC and anemia panel blood test in September - and my RBC, ferritin, hemoglobin and hematocrit were low (for the first time in my life!). Further work up ruled out other types of anemia. I was diagnosed with iron deficiency anemia (for the first time in my life). Now I am taking iron pills.
I am not taking a booster shot, and I am reluctant to vaccinate my children. There were no events or reasons (other than vaccine) that would cause me to be anemic and unable to function for six months.
