On 16 May people from within and outside MSF will gather in London, joined by online participants from over 100 countries, for this annual ‘conference without borders’ showcasing medical research from fragile and conflict affected settings. All too often the populations MSF and others work with are excluded from the benefits of research. Yet they are the ones that often need these benefits most. So speakers will consider how MSF’s research has impacted the way our projects deliver care, how knowledge gaps can be pivotal to political gatekeeping and to triggering appropriate humanitarian responses, and how identifying best practices and funding innovation are key to improving our capacity to act. Here you can view abstracts for all scientific presentations, which focus on infectious diseases, outbreaks, vaccination, and mortality.
