When an organ is replaced with someone else’s, the body needs immunosuppressants because of the foreign object now in the body. Why is the same not true for a blood transfusion?

Answer 1

You might need some immunosuppressants with blood transfusions as well. However the blood that is being transfused is just temporary and does not linger long in the body. So there is little chance of rejection.
