All Sonar-Global partners work in the field of “infectious threats”. Our scope of action includes preparedness and response to epidemics, vaccine hesitancy, and the prevention of antimicrobial resistance. As social scientists, we recognize that efforts to tackle these threats may be ineffective if complex social, political, economic and ecological contexts are not addressed. The Sonar-Global platform provides opportunities for social scientists to work together and to build bridges. Through this platform, we create a critical mass of social scientists with whom we can share experiences, tools, models and curricula. We also foster closer collaborations with experts from other disciplines.
