Scientists behind AstraZeneca vaccine say it has similar efficacy against variant as against original Covid
The Oxford/AstraZeneca coronavirus vaccine is just as effective at fighting the UK variant as it is the original virus, new research suggests.
Oxford University researchers who developed the vaccine say it has a similar efficacy against the variant first detected in Kent and the south-east of the UK as it has against the original form of Covid-19 that it was tested on.
