Institutional quality and COVID-19 vaccination: does decentralization matter?

Abstract

Vaccination campaigns are one of the factors that can help mitigate the adverse effects of viral pandemics. The aim of this paper is to understand the institutional factors that are associated with a higher success rate, measured by the percentage of vaccinated population against COVID-19 across countries. Along with supply side determinants, institutional factors, related, at the national level, to the organization of the healthcare sector, governance and organization of the State and social capital, and, at the subnational level related to the authority and autonomy of lower tiers of government, are important correlates of successful vaccination campaigns, suggesting potential areas of public policy interventions.
