Hi Lynn,
As far as I understand the antibodies against RBC:s won´t disappear.
I developed antibodies very soon after my first transfusions. It takes hours to find blood that I can have because of all my antibodies. To prevent hemolysis I always get 100 mg Solucortef (cortison) before transfusions but I don´t think it has much effect.
