Chronic lymphocytic leukaemia is the most common leukaemia in New Zealand. Currently, the only treatment is chemotherapy, which is often ineffective, or a bone marrow transplant.
Robert Weinkove is a haematologist working at Wellington Hospital and the Malaghan Institute of Medical Research. He is trying to develop a new therapy which would stimulate the patient's own immune system to fight the leukaemia cells.
Often called a cancer vaccine, Ruth Beran went to meet him in the lab to find out more about this type of immunotherapy.
