The first human trial in Europe of a coronavirus vaccine has begun in Oxford.
Two volunteers were injected, the first of more than 800 people recruited for the study.
Half will receive the Covid-19 vaccine, and half a control vaccine which protects against meningitis but not coronavirus.
The design of the trial means volunteers will not know which vaccine they are getting, though doctors will.
The vaccine was created in under three months by a team at Oxford University. Sarah Gilbert, professor of vaccinology at the Jenner Institute, led the pre-clinical investigate.
