Health biotechnology innovation on a global stage

With increasing globalization, infectious diseases are spreading faster than ever before, creating an urgent need for international collaboration. The rise of emerging economies has changed the traditional collaborative landscape and provided opportunities for more diverse models of collaboration involving developing countries, including North–South, South–South and North–South–South partnerships. Here, we discuss how developing countries can partner with other nations to address their shared health problems and to promote innovation. We look specifically at what drives collaborations and at the challenges that exist for them, and we propose actions that can strengthen these partnerships.
