The COVID-19 vaccine developed by Oxford University and produced by AstraZeneca has shown efficacy against the UK variant of the coronavirus, according to an ongoing study by researchers.

Oxford University scientists who developed the ChAdOx1-nCoV19 vaccine have found that it remains effective against at least one of the new variants of the disease, called the B.1.1.7 ‘Kent’ coronavirus strain after the south-east England region where it was first discovered late last year.
