Moderna Covid-19 Vaccine Rolled Out in U.K. for First Time Bloomberg 3 hrs ago Emily Ashton (Bloomberg) -- The U.K. began rolling out the Moderna Inc. vaccine on Wednesday, bolstering Britain’s Covid-19 immunization program amid concerns over AstraZeneca Plc’s shot and a shortfall of doses this month. Health Secretary Matt Hancock said the Moderna shot would first be offered in west Wales. It is the third approved vaccine to be offered in Britain, alongside shots from AstraZeneca and partners Pfizer Inc. and BioNTech SE, and its rollout is around two weeks earlier than expected. The U.K. has ordered 17 million doses of Moderna’s two-shot vaccine, enough for 8.5 million people.
