Covid-19 vaccination achievement 'no moment to relax' - PM - BBC News
Boris Johnson calls the vaccination programme an unprecedented achievement and thanks those involved.
The Oxford-AstraZeneca vaccine has been approved by the World Health Organization for emergency use, which means it will be part of the WHO’s global vaccine-sharing scheme Covax.

The vaccine will be produced at two plants - by SKBio in South Korea and the Serum Institute of India - and so had to be approved twice.

"We now have all the pieces in place for the rapid distribution of vaccines," WHO Director-General Tedros Adhanom Ghebreyesus said.

"But we still need to scale up production."

The Oxford vaccine is seen as the "vaccine for the world" as it is cheap, can be mass produced and is stored in a standard fridge.

It has attracted controversy about its effectiveness against new variants, whether it should be used in the elderly and how far apart the doses should be given, due to a lack of data.

But a review by the WHO found that it met the "must-have" criteria for safety, and its benefits outweighed the risks.
