South Africa has rolled out the continent's first coronavirus vaccine trial this week.

The university leading the pilot has said, as the country grapples with the highest number of cases in Africa.

The vaccine, developed by the Oxford Jenner Institute, is already being evaluated in the United Kingdom, where 4,000 participants have signed up for the trial.

South Africa has set out to vaccinate 2,000 people with the vaccine known as ChAdOx1 nCoV-19. Fifty of the candidates have HIV.
