The UK government plans to offer a first dose of Covid-19 vaccine to every adult by September as the nation’s health care system battles the worst crisis in its 72-year history, AP reports.

Foreign Secretary Dominic Raab said the government will soon begin a trial of round-the-clock injections at some locations as it continues to add more vaccination sites to increase the pace of delivery.

“Our target is by September to have offered all the adult population a first dose,” he told Sky News. “If we can do it faster than that, great, but that’s the road map.”
