Britain begins rolling out Moderna’s Covid-19 vaccine in Wales today and expects to be using it in the rest of the United Kingdom in the coming days in a boost to the country’s health system after supplies of shots started to slow, Reuters reports.

Moderna will become the third vaccine to be used in Britain after the Oxford-AstraZeneca and Pfizer jabs and comes as the supply of shots from Astra starts to slow due to manufacturing issues including at a site in India.

“I’m delighted we can start the UK rollout of the Moderna vaccine in west Wales today,” health secretary Matt Hancock said. “Today we start with the third approved vaccine. Wherever you live, when you get the call, get the jab.”
