Covid-19: Oxford University vaccine shows 70% protection
Author: James Gallagher
It will be seen as a triumph, but also comes off the back of Pfizer and Moderna showing 95% protection.
However, the Oxford jab is far cheaper, and is easier to store and get to every corner of the world than the other two.
So it will play a significant role in tackling the pandemic, if it is approved by regulators.
There is also intriguing data that suggests perfecting the dose could increase protection up to 90%.
The UK government has pre-ordered 100 million doses of the Oxford vaccine, enough to immunise 50 million people.
Prime Minister Boris Johnson said: "Incredibly exciting news the Oxford vaccine has proved so effective in trials.
"There are still further safety checks ahead, but these are fantastic results."
The vaccine has been developed in around 10 months, a process that normally takes a decade.
"The announcement today takes us another step closer to the time when we can use vaccines to bring an end to the devastation caused by [the virus]," said the vaccine's architect Prof Sarah Gilbert.
What did the trial show?
More than 20,000 volunteers were involved, half in the UK, the rest in Brazil.
There were 30 cases of Covid in people who had two doses of the vaccine and 101 cases in people who received a dummy injection.
