Changes have been made to the vaccination groups, with higher priority for those with underlying medical conditions that put them at risk if they catch Covid-19.

After the over-70s are vaccinated, those aged 16 to 69 at very high risk of disease or death will be immunised. They will be followed by those aged 65 to 69 years at high risk.

Professor Karina Butler, Chair of National Immunisation Advisory Committee joins Kieran to discuss the changes.
