Global Health Emergencies (GHEs) are crises that affect health, and that are, or should be, of international concern. These might include infectious outbreaks, humanitarian crises and disasters, conflicts, and forced displacements. GHEs are characterised by various forms of urgency and uncertainty, and are known to exacerbate existing inequalities, injustices and vulnerabilities in individuals and communities. This is a Wellcome Trust Seed Award Project entitled, ‘Vulnerability and justice in global health emergency regulation: developing future ethical models’.
