It's no secret why poor countries don't have as many vaccines as rich countries.
"There's really just a scarcity of doses," says Kate Elder, senior vaccine policy adviser at Doctors Without Borders' Access Campaign. The question is, how do you fix it?
In the U.S., more than 1 out of every 5 residents is fully vaccinated against COVID-19. The U.S. and several other wealthy nations, including Canada and many European Union member states, are on track to vaccinate most of their populations by mid-2022, according to a report from
The Economist.
But elsewhere in the world, vaccination rates are much lower. The entire continent of Africa, for example, has administered just 2% of the world's vaccine doses so far. Some poor nations including Haiti have yet to receive a single vaccine dose.
