Africa could have a Covid-19 coronavirus vaccine in the first quarter of 2021 if human trials underway in South Africa succeed, a university professor heading the trials said.
The ChAdOx1 nCoV-19 experimental vaccine is one of 19 being tested on humans globally in a race to find vaccines to stop a pandemic that has killed more than half a million people so far.
It is also being tested in Brazil by Oxford University scientists who are working with British drugmaker AstraZeneca on development and production.
