By the time you read this I’ll be home from Liverpool, in the north-west of England. where last week, on behalf of RESULTS Australia, I attended the International Union Against Tuberculosis and Lung Disease (‘The Union’). The 47th World Conference, addressed a wide range of issues affecting adult and child lung health including air pollution, pneumonia, tobacco control -- and, of course, tuberculosis (TB). Global scientific gatherings like this -- over 3000 people attended -- are, as you’d expect, very much about new biomedical discoveries: in bacteriology, immunology, drugs and diagnostics, disease prevention, patient care and links between TB and diseases such as HIV and diabetes. So this got me thinking: what is the role of advocacy at a scientific conference?
