The developers of a coronavirus vaccine in Britain on Monday claimed success after mass testing, as the United States announced plans to give jabs to 20 million people before the end of the year to combat surging infections.
AstraZeneca and Oxford University said their drug had proved on average 70 percent effective at stopping the virus after trying it on 23,000 people, days after tests of two other drugs suggested they had more than 90 percent effectiveness.
The bright news on vaccines comes as Europe and the Americas battle rising caseloads that are pushing health systems to the brink, forcing governments to issue stay at home orders and close businesses even as the crucial Christmas period approaches.

At the other end of the confinement cycle, Australia’s second-largest city Melbourne continued to emerge from a gruelling four-month lockdown with authorities lifting a ban on travel across state borders.
“When I went across the border I beeped the horn, ‘Yahoo!’,” said Melbourne resident Margaret Forster after being allowed to drive from Victoria into New South Wales for the first time since June.
The virus has killed almost 1.4 million people worldwide since emerging in China late last year.
