Scientists in Britain began clinical trials of a potential COVID-19 vaccine on Thursday as other vaccine developers across Europe also stepped up work on their own experimental shots against the disease caused by the new coronavirus.
A team at Britain's Oxford University dosed the first volunteers in a trial of their vaccine - called "ChAdOx1 nCoV-19" - while Italy's ReiThera, Germany's Leukocare and Belgium's Univercells said they were working together on another potential shot and aimed to start trials in a few months.
Britain's GSK and France's Sanofi last week announced a similar agreement to develop a COVID-19 vaccine, with trials starting in the second half of the year.
