Because the doctors have done tests and everything and they cannot figure out why her red blood cells are dropping or the B12 was dropping and D3 was dropping." Treatment: Consumer stated, "Yes, she had iron infusion and she had been on strong Iron pill and 50000mg of the D3 and a 1000 of the B12."

Consumer also stated, "she thought since she had Pfizer shot (Unspecified vaccine) she thought she developed iron deficiency anemia and her B12 have dropped again and D3 had dropped again and she had conference with 2 pharmacist and gone over her medicine everything and she had iron infusion because she had no energy to do anything and the only thing she could come up with she had to go back to hematologist on 17th on this month because she called today and asked if she can get another iron infusion shot but they told her she had to do her lab work first to see where she was at before she can get second infusion. But she thought since she had the shot last year her first shot was 20Feb2020 and then March, she had to make a correction, it was 20Feb2021 and then her second short was 13Mar2021 and she just got her booster shot 15Oct2021. And she thought may be the side effect, she thought she was no doctor she just thought in 05Jun she started having problems with her red blood cells dropping and she had no energy to do anything. she thought she was being tired because she just moved in June so she thought she was just being tired from the move, so she moved the first week of Jun and so the second week she can't do anything because she was still tired, but third week she said something was quite not right and then the last week of Jun she can barely move and then she knew something was wrong and then she called to make appointment because she just can hardly do anything, she was just so exhausted all the time even after having her iron infusion (Unspecified infusion) in Oct. So, she was wondering was that one of the side effects of having Pfizer shot."
