Britons are being urged to take part in a trial for a potential coronavirus vaccine and could be paid up to £625 for their time. Imperial College London and University Hospital Southampton has asked people to take part in some of the first human tests to discover whether a potential inoculation is effective in tackling the deadly disease. Yesterday Health Secretary Matt Hancock announced that one Covid-19 vaccine developed at the University of Oxford will be trialled on humans in the UK from tomorrow. Imperial said tests for its separate vaccine will take place in the weeks ahead and anyone who is healthy and aged between 18 and 55 can take part at Imperial College London, University Hospital Southampton or Bristol Children’s Vaccine Centre.
