South Africa has concluded the sale of AstraZeneca COVID-19 vaccines it had acquired—but did not use—to other African Union (AU) member states, the country’s health ministry said on Sunday, Reuters reported.

The country had paused AstraZeneca vaccinations last month because of a small trial showing the shot offered minimal protection against mild to moderate illness caused by the dominant local coronavirus variant.

At the time, South Africa had received 1 million AstraZeneca doses, and the delivery of another 500,000 was pending.

The ministry said it had in the past weeks worked to ensure that all member states identified by the AU vaccines acquisition teams as recipients of the vaccines were compliant and had obtained all regulatory approvals, permits and licenses to roll out the vaccines in their respective countries.

After pausing the roll-out of the AstraZeneca vaccine, South Africa started inoculating healthcare workers with Johnson & Johnson shots in a research study.
