Nadhim Zahawi suggests annual vaccines or autumn booster could help keep on top of mutating virus
The vaccines minister, Nadhim Zahawi, has said people may need a Covid booster jab in autumn as more variants of the virus emerge, although the government is still confident current vaccines will prevent severe symptoms.
His comments came following the release of a study showing the Oxford/AstraZeneca jab has reduced efficacy against the South African variant.
