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... Around a fifth of the volunteers in this trial were over 65 and the vaccine - given as two doses, four weeks apart - provided as much protection to them as to younger age groups.
