Comparison of ICER and vaccine purchase cost per dose by income regions

Vaccine purchase cost per dose was converted to I$ using the World Bank and International Monetary Fund price level ratios of gross domestic product (at purchasing power parity) per capita to market exchange rate in 2015. Each point on the chart represents one country. Countries with higher vaccine cost had lower cost-effectiveness of vaccination (higher ICER). DALY=disability-adjusted life-year. ICER=incremental cost-effectiveness ratio. I$=international dollars.
