Public support in the United States for global equity in vaccine pricing

Abstract

Global vaccine prices that are tiered across countries, equitable for poorer countries, and profitable for manufacturers (TEP) can promote global vaccine equity but its implementation may require political will and public support in rich countries. A survey experiment with a demographically representative sample of US adults was conducted between April and May 2021 to investigate public support for TEP and the likelihood of collective agreement on TEP relative to alternative global vaccine pricing strategies. The experiment varied vaccine cost and provision of information about the importance of equity and profitability considerations in global vaccine pricing across eight treatment conditions. TEP of low-cost vaccines received less support than TEP of high-cost vaccines, but TEP received more public support than any alternative pricing strategy. Information about equity and profitability considerations increased support for TEP of low-cost vaccines. TEP was also the most likely pricing strategy to achieve collective agreement among participants across all treatments.
