Graft Versus Host Disease (GvHD) occurs when the white blood cells in a transplanted organ or bone marrow begin to attack other cells in the recipient’s body. It also occurs, rarely, after some blood transfusions where the blood is not first irradiated. It results in inflammation in various organs, and can increase chances for systemic infection - a dangerous complication.
