Why the continent's only vaccine plant is struggling

 The global organisations that buy Covid vaccines for poorer countries "need to step up" and order doses from Africa's only Covid vaccine maker in order to save the production line, the company's senior executive told the BBC.

This follows warnings from Aspen Pharmacare that it may have to stop production at its South African plant.It has been hit by low demand.

Fewer than one in six Africans have had two doses of a coronavirus vaccine, with many reluctant to get jabbed.

The continent's top health body has also urged those buying the jabs for Africa to place orders with Aspen.
