Who will be first in line for Covid vaccine?

The UK is the first country in the world to approve mass use of a Covid vaccine.

Immunisations with the Pfizer-BioNTech vaccine, approved by the British medicines regulator, the MHRA, could start early next week for people in some high-priority groups, with 800,000 doses arriving in the UK in the first delivery.

The BBC’s Laura Foster explains who will be first in line to receive the vaccine and why.
