Competing Responses to Global Inequalities in Access to COVID Vaccines: Vaccine Diplomacy and Vaccine Charity Versus Vaccine Liberty

Global access to coronavirus vaccines has been extraordinarily unequal and remains an ongoing source of global health insecurities from the evolution of viral variants in the bodies of the unvaccinated. There have nevertheless been at least 3 significant alternatives developed to this disastrous bioethical failure. These alternatives are reviewed in this article in the terms of “vaccine diplomacy,” “vaccine charity,” and “vaccine liberty.” Vaccine diplomacy includes the diverse bilateral deliveries of vaccines organized by the geopolitical considerations of countries strategically seeking various kinds of global and regional advantages in international relations. Vaccine charity centrally involves the humanitarian work of the global health agencies and donor governments that have organized the COVAX program as an antidote to unequal access. Despite their many promises, however, both vaccine diplomacy and vaccine charity have failed to deliver the doses needed to overcome the global vaccination gap. Instead, they have unfortunately served to immunize the global vaccine supply system from more radical demands for a “people’s vaccine,” technological transfer, and compulsory licensing of vaccine intellectual property (IP). These more radical demands represent the third alternative to vaccine access inequalities. As a mix of nongovernmental organization-led and politician-led social justice demands, they are diverse and multifaceted, but together they have been articulated as calls for vaccine liberty. After first describing the realities of vaccine access inequalities, this article compares and contrasts the effectiveness thus far of the 3 alternatives. In doing so, it also provides a critical bioethical framework for reflecting on how the alternatives have come to compete with one another in the context of the vaccine property norms and market structures entrenched in global IP law. The uneven and limited successes of vaccine diplomacy and vaccine charity in delivering vaccines in underserved countries can be reconsidered in this way as compromised successes that not only compete with one another, but that have also worked together to undermine the promise of universal access through vaccine liberty.
