A team of scientists at Newcastle University is preparing a small human trial to test a one-shot approach to curing rheumatoid arthritis with a vaccine devised from a patient's white blood cells. The cells are taken from the volunteers and manipulated with a recipe of chemicals, steroids and Vitamin D so they can suppress the immune system rather than spur it. And a single jab could be enough to suppress the auto-immune response that triggers rheumatoid arthritis. Report
