I have had 4 of the Pfizer vaccines. In December 2022 I collapsed on an overseas trip. Diagnosis iron-deficiency anemia. Had scopes. I had been feeling sick for about 4 months but doctor diagnosed high blood pressure. Now had two iron infusions and on iron supplements. SLOWLY feeling better but hearing more and more people in my community who had had vaccine and have been diagnosed with iron deficiency anemia. Doctor will repeat bloods May 2023 to see if there is an improvement. The doctor who did the scopes expressed concerns that the Covid vaccine could be responsible. I live in South Africa, but my daughter's friends and colleagues in Australia are reporting the same incidents of anemia!
