結果 (英文) 1:

Foreign antigens into the patient, the immune system will produce antibodies to this antigen identification, when the same antigen meet again quickly initiate the immune response, so transfusion reactions occur more frequently in patients with multiple transfusions and prolific women

結果 (英文) 2:

When an external antigen enters the patient, the immune system produces antibodies that recognize the antigen, and when the same antigen is met again, the immune response can be activated quickly, so the blood transfusion response is more common in patients with multiple blood transfusions and in prolific women.
