Access on the Rocks

Among the myriad challenges of distributing a COVID-19 vaccine across remote swathes of Africa, South America, and Asia: keeping vaccines cold.

Some of the most promising vaccine candidates may need to be stored at “Antarctic-level temperatures.”
Outside of the 25 most advanced countries—where a third of the global population lives—making the necessary upgrades to cold storage will be a mammoth logistical challenge.
Manufacturers are aiming to compensate by making their product hold up longer in transit.
But even with a cold chain that only requires temperatures of -8C, huge portions of Africa would still be left without reliable access.
