Modelled HIV residual risk estimates increased slightly with relaxed policies on donations from men who have sex with men. However, differences in risk and blood volume estimates between different policies are generally very small. To support decisions on easing donor policies for men who have sex with men, models should also quantify residual risks for non-HIV transfusion-transmissible infections, such as syphilis.
