Scientists in London are offering to pay volunteers £3,500 ($4,500) to be infected in experiments to develop a vaccine, according to the Daily Star and the Daily Mail.

Hvivo, which owns the Queen Mary BioEnterprises Innovation Centre in east London, is looking for volunteers willing to be injected with the 0C43 and 229E strains of the coronavirus as part of research into the development of a vaccine.

These strains are far less serious than the COVID-19 strain currently spreading across the world, giving them similar respiratory symptoms.
