NYC Beaches to Open in May; U.K. Rolls Out Moderna: Virus Update Bloomberg 44 mins ago Bloomberg News (Bloomberg) -- The European Union drug regulator said it found a “possible link” between the AstraZeneca Plc vaccine and a rare blood-clotting disorder, but determined the benefits of the shot outweigh the risks. The U.K.’s regulator echoed that view, though it recommended not using the shot on those under age 30. The U.K. began rolling out Moderna Inc.’s vaccine, bolstering Britain’s immunization program amid concerns over the Astra shot and a shortfall of doses. Moderna said it’s on track to meet April vaccine commitments after a report that it would miss a delivery to Germany.
