Britain’s drug regulator on Wednesday approved the Oxford-AstraZeneca COVID-19 vaccine for use in the UK, according to an official statement.

Axar.az reports citing foreign media that starting today the National Health Service “will prioritise giving the first dose of the vaccine to those in the most high-risk groups,” said a statement from the Department of Health and Social Care.

“With two vaccines now approved, we will be able to vaccinate a greater number of people who are at highest risk, protecting them from the disease and reducing mortality and hospitalization,” it added.

The UK rolled out the Pfizer/BioNTech vaccine in early December.
