evidence: The Chinese government shared the genetic sequence of coronavirus on 11 January, and within weeks a team at the University of Oxford had developed an experimental vaccine. Their human trial, the first in Europe, began last month. More than 1,000 volunteers are now part of the Oxford vaccine study. Half will get ChAdOx1 nCoV-19, as the vaccine is called, and the rest a control vaccine which protects against meningitis. The trial is "blinded" so that the researchers and the volunteers won't know which jab they are getting. [...] And the Oxford vaccine is not the only show in town. Imperial College London is developing a coronavirus vaccine which will begin human trials next month. All the researchers I've spoken to have said this is not a race to be first, but a race against the virus. It's a race we all hope they will win.
