UK scientists will start testing another potential coronavirus vaccine on humans this week. Imperial College London's clinical trials will start with 300 people, to see whether their jab produces an effective immune response against Covid-19.
The healthy participants, aged between 18 and 70, will all receive two doses of the vaccine over the coming weeks, and the hopes are that tests could then move on to 6,000 volunteers if they are successful.
Rather than giving people a weakened form of the illness, the Imperial vaccine instead uses synthetic strands of genetic code based on the virus' genetic material.
The research has been funded by £41m from the UK Government, as well as £5m of other donations, and comes after a separate vaccine from
