In September 2021, the World Health Organization (WHO) set an ambitious global target. The UN health agency called for 70 per cent of the global population to be vaccinated by mid-2022.
At that point, just over three per cent of people in low-income countries had been vaccinated with at least one dose, compared to 60.18 per cent in high-income countries.
Six months on, the world is nowhere near reaching that target.
The overall number of vaccines administered has risen dramatically, but so has the inequality of the distribution: of the more than 10 billion doses given out worldwide, only one per cent have been administered in low-income countries.
