The research team from the University of Newcastle is developing the jab, which involves taking cells from the RA patient, altering them and injecting them back into the affected joint.
The process works like a vaccine and changes human cells to suppress the immune system. This would prevent the body from attacking its own joints.
The researchers will test the effectiveness of the new vaccine in eight volunteers with RA as part of a pilot study, which could then lead to larger trials.
Lead researcher John Isaacs, professor of clinical rheumatology at Newcastle University's Musculoskeletal Research Group, said that the work was at a very early, experimental stage.
