Philanthropic and aid agency funders provide the vast majority of PDP funding, with the Gates Foundation in the lead. In Europe, the United Kingdom is very active, supporting PDPs with 200 million euros in research funding over five years. In addition, together with the Gates Foundation, the UK government recently launched a research and care fund to combat malaria and other infectious diseases that is supported with 1.5 billion euros.
