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, BBC reported.
The design of the trial means volunteers will not know which vaccine they are getting, though doctors will.
Elisa Granato, one of the two who received the jab, told the BBC: “I’m a scientist, so I wanted to try to support the scientific process wherever I can.”
The vaccine was developed in under three months by a team at Oxford University. Sarah Gilbert, professor of vaccinology at the Jenner Institute, led the pre-clinical research.
The Oxford team has already developed a vaccine against Mers, another type of coronavirus, using the same approach – and that had promising results in clinical trials.
