China to run human coronavirus vaccine trial in UAE: China is seeking to trial potential vaccines overseas because of a lack of new patients at home.

Over a dozen experimental vaccines are being trialled around the world. None of them has yet successfully completed a late-stage “Phase 3” test to determine efficacy in shielding healthy people from the virus, which has killed over 470,000 people around the world.

Such trials involve thousands of participants and normally take place in countries where the virus is widespread, so that the vaccine can be observed in a real-life environment.
