Covid vaccine a 'glimmer of light' for Wales
Rollout of a new vaccine against coronavirus will begin within days in Wales.
The doctor in charge of the vaccination programme said it provided a "glimmer of light" after a year of darkness under the pandemic.
Dr Gill Richardson said the Pfizer-BioNtech vaccine approved in the UK was safe and had undergone thorough testing.
However, she said delivering a massive vaccine programme posed significant challenges.
