South Africa has put its rollout of the Oxford-AstraZeneca vaccine on hold after a study showed "disappointing" results against its new Covid variant.
Scientists say the variant accounts for 90% of new Covid cases in South Africa.
The trial, involving some 2,000 people, found that the vaccine offered "minimal protection" against mild and moderate cases.
But experts are hopeful that the vaccine will still be effective at preventing severe cases.
