The race to develop an effective vaccine against the novel corona-virus gathered pace this week, as clinical trials on humans were approved in Germany and launched in the UK.
Though there are now around 150 development projects worldwide, the German and British plans are among only five clinical trials on humans which have been approved across the globe.
In Britain, volunteers in a trial at the University of Oxford are set to be given on Thursday the first dose of a potential vaccine based on a virus found in chimpanzees.
Meanwhile on Wednesday, German regulatory body PEI green-lighted the country's first trials on human volunteers for a vaccine developed by German firm Biotech and US giant Pfizer.
