Terrence Higgins Trust on lifting of lifetime ban on gay men giving blood

First Minister Arlene Foster has backed the lifting of a lifetime ban on gay men donating blood. The DUP leader said she was presented with new medical evidence on the issue by Sinn Féin Health Minister Michelle O'Neill. Mrs Foster says the decision was backed by science. Stephen spoke to Shaun Griffin, Executive Director for External Affairs at the Terrence Higgins Trust, a charity which campaigns on Aids and HIV issues.
