Hopes have been raised that vaccines could end the coronavirus pandemic after a British jab was found to be up to 90% effective in preventing Covid-19.

AstraZeneca and Oxford University said their jab is effective in stopping most people from contracting coronavirus and falling seriously ill, with some indications that it can also prevent people passing the virus to others.
