Virologists cast doubt on efficacy of vaccine

Virologists have called into question the efficacy of a novel coronavirus vaccine being developed by a United Kingdom pharmaceutical company and researchers at Oxford University.

The vaccine, known as ChAdOx1 nCoV-19, or more commonly the Oxford vaccine, is undergoing clinical trials in humans and has received large amounts of government funding from both the UK and the United States.

The Jenner Institute and Oxford Vaccine Group－both at the University of Oxford－are collaborating on the vaccine alongside Cambridge-based pharmaceutical company AstraZeneca, which will manufacture and distribute the treatment.
