Covid-19: Oxford University vaccine shows 70% protection
The coronavirus vaccine developed by the University of Oxford stops 70% of people developing Covid symptoms, a large-scale trial shows.
It will be seen as a triumph, but it 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.
