Global vaccine inequities and multilateralism amid COVID-19: Reconnaissance of Global Health Diplomacy as a panacea?

Background: The ongoing COVID-19 pandemic has shown a crystal-clear warning that nobody will be safe until everybody is safe against the pandemic. However, how everyone is safe when the pandemic's fat tail risks have broken every nerve of the global economy and healthcare facilities, including vaccine equity. Vaccine inequity has become one of the critical factors for millions of new infections and deaths during this pandemic. Against the backdrop of exponentially growing infected cases of COVID-19 along with vaccine in-equity, this paper will examine how multilateralism could play its role in mitigating vaccine equity through Global Health Diplomacy (GHD). Second, given the most affected developing countries' lack of participation in multilateralism, could GHD be left as an option in the worst-case scenario?. Methods: In this narrative review, a literature search was conducted in all the popular databases, such as Scopus, Web of Science, PubMed and Google search engines for the keywords in the context of developing countries and the findings are discussed in detail. Results: In this multilateral world, the global governance institutions in health have been monopolized by the global North, leading to COVID-19 vaccine inequities. GHD aids health protection and public health and improves international relations. Besides, GHD facilitates a broad range of stakeholders' commitment to collaborate in improving healthcare, achieving fair outcomes, achieving equity, and reducing poverty. Conclusion: Vaccine inequity is a major challenge of the present scenario, and GHD has been partly successful in being a panacea for many countries in the global south.
