Summary Understanding the complex immunological consequences of red cell transfusion is essential if we are to use this valuable resource wisely and safely. The decision to transfuse red cells should be made after serious considerations of the associated risks and benefits. Immunological risks of transfusion include major incompatibility reactions and transfusion‐related acute lung injury, while other immunological insults such as transfusion‐related immunomodulation are relatively underappreciated. Red cell transfusions should be acknowledged as immunological exposures, with consequences weighed against expected benefits. This article reviews immunological consequences and the emerging evidence that may inform risk‐benefit considerations in clinical practice.
