AstraZeneca, Moderna ahead in COVID-19 vaccine race - WHO

AstraZeneca's experimental COVID-19 vaccine is probably the world's leading candidate and most advanced in terms of development, the World Health Organization's (WHO) chief scientist said on Friday. The British drugmaker has already begun large-scale, mid-stage human trials of the vaccine, which was developed by researchers at University of Oxford. This week, AstraZeneca signed its tenth supply-and-manufacturing deal.
