South Africa’s health department confirmed on Friday that the country is paying $5.25 per dose of the Oxford-AstraZeneca vaccine - 2.5x more than what European Union members are set to pay.

“The explanation we were given for why other high-income countries have a lower price is that they have invested in the [research and development], hence the discount on the price,” said Anban Pillay, South Africa’s deputy director general of health

The price difference between the EU and South Africa has the potential to deepen the effects of vaccine nationalism, where wealthier countries have been buying up more than enough vaccines to inoculate their populations — several times over in some cases — leaving middle- and lower-income countries struggling to access the vaccine.

The World Health Organisation warned against vaccine nationalism earlier this month, with the WHO chief, Dr. Tedros Adhanom Ghebreyesus, saying that “the world is on the brink of a catastrophic moral failure.”
