DFID funding for the Global Fund to Fight AIDS, TB and Malaria is to support the scale-up of services, rather than research. DFID has doubled its pledge for 2006 and 2007 to £100 million annually, subject to performance. DFID currently supports the research and development of TB drugs and diagnostics through its funding to the World Health Organisation (WHO) Special Programme for Research and Training in Tropical Diseases (TDR) and the public/private Product Development Partnership, the Global Alliance for TB Drug Development. TDR will receive £4.5 million over three yeas, from 2005 to 2008. The Global Alliance for TB Drug Development will receive £6.5 million from 2005 to 2008 for the development of new TB drugs.
