LONDON - Health officials started using the Moderna jab in Wales last week and had said it would be rolled out across the rest of the United Kingdom in the coming days.
"More than 20 sites, including Reading's Madejski Stadium and the Sheffield Arena, will initially use the newest vaccine, as the NHS continues to expand the vaccination programme," the health service said in a statement.
