The University of Oxford’s COVID-19 vaccine trial has only a 50-percent chance of success as coronavirus cases ebb in the UK, the professor co-leading the development of the vaccine told the Daily Telegraph newspaper.
Adrian Hill, director of Oxford’s Jenner Institute, which teamed up with drugmaker AstraZeneca Plc to develop the vaccine, ChAdOx1, said an upcoming trial involving 10,000 volunteers threatened to return “no result” due to low COVID-19 transmission in the community.
“At the moment, there’s a 50-percent chance that we get no result at all,” Hill told the British newspaper.
Human trials of the vaccine started in April.
