Access and benefit sharing (ABS) is a transactional mechanism designed to allow countries to trade access to their sovereign genetic resources for monetary and non-monetary benefits, with the ultimate goal of channelling those benefits into sustainable development and environmental conservation. Arguments about how pathogens are not the sort of genetic resources the world ought to conserve eventually gave way to a recognition that pathogens are indeed sovereign genetic resources under the Convention on Biological Diversity and its Nagoya Protocol, and that the ABS transaction may be an effective way to deliver scarce vaccines to developing nations as benefits received in exchange for shared pathogen samples. This article argues that categorising vaccines as benefits given in exchange for access to pathogen samples creates opposing incentives for providers and users of virus samples and undermines the human right to health because it makes that right a commodity to be bought. The provision of pathogen samples to the global research commons and the fair and equitable distribution of medicines should be two parallel public goods to be pursued as goals in and of themselves. We conclude that the linking of these goals through the ABS transaction should be reassessed.
