A preprint of ongoing work to assess effectiveness of Oxford’s ChAdOx1 coronavirus vaccine shows that the existing vaccine has similar efficacy against the B.1.1.7 ‘Kent’ coronavirus strain currently circulating in the UK to previously circulating variants.

Our vaccine work is progressing quickly. To ensure you have the latest information or to find out more about the trial, please visit the Oxford COVID-19 vaccine web hub or visit the COVID-19 trial website.

The Oxford University researchers who developed the ChAdOx1-nCoV 19 vaccine have found that it remains effective against one of the new variants of the disease.

The preprint also describes recent analysis showing that vaccination with ChAdOx1 nCoV-19 results in a reduction in the duration of shedding and viral load, which may translate into a reduced transmission of the disease.

Andrew Pollard, Professor of Paediatric Infection and Immunity, and Chief Investigator on the Oxford vaccine trial, said:

‘Data from our trials of the ChAdOx1 vaccine in the United Kingdom indicate that the vaccine not only protects against the original pandemic virus, but also protects against the novel variant, B.1.1.7, which caused the surge in disease from the end of 2020 across the UK.’

Sarah Gilbert, Professor of Vaccinology, and Chief Investigator on the Oxford vaccine trial, said:

‘All viruses accumulate mutations over time, and for influenza vaccines there is a well-known process of global viral surveillance, and selection of strains for an annual update of the vaccines.’
