Results from the long-awaited US trial of the Oxford-AstraZeneca Covid vaccine are out and confirm that the shot is both safe and highly effective.
More than 32,000 volunteers took part, mostly in America, but also in Chile and Peru.
The vaccine was 79% effective against stopping symptomatic Covid disease and 100% effective at preventing people from falling seriously ill.
And there were no safety issues regarding blood clots.
That should further reassure some EU countries that recently paused rollout of the vaccine amid concerns about a possible link.
Some are already starting to use it again now that Europe’s medicines regulator has completed its review and has also concluded the vaccine is safe and effective.
