Steadily Increasing Correlation between People Vaccinated per Hundred and GDP per capita

The WHO announced that wealthy countries had received the largest supply of the world's COVID-19 vaccines while developing countries received only 0.2% of the global supply. Despite the outcry, the correlation between the people vaccinated per hundred and the GDP per capita steadily increased from Dec. 2020 to Sep. 2021. The disparities between low-income and high-income countries constantly increased as more vaccines became available and administered throughout the year.
