Had my Pfizer vaccine 1 and 2 in Sep 2021. In December I was having issues with my tongue, burning and nothing tasting good. Went to my Doc in Jan 2022 and had blood test All red blood cell counts low. Hemoglobin - 8.3. Hemacrit - 30.4. MCV and MCH low. First time ever having this issue and I am 76. Get blood tests twice a year. Referred to Hematologist. First test on 2/4/22 Iron 13 and Saturation was 3. Had an Infusion a few days later. Second test 3/14/22, Iron 22 and Saturation 6%. All these problems started after the Phizer vaccines in September so do I blame an unapproved vaccine, definitely. I still work and my company required me to take the vaccine or I would not have taken it. I would not take it again for sure.
