Children over 12 who are at higher risk of getting ill if they catch Covid will be offered the jab, the vaccines minister Nadhim Zahawi has confirmed.
But the vast majority of children in the UK, who are low risk, will not be offered the vaccine for now.
However, some healthy children over 12 who live with other vulnerable people can have the vaccine, as well as those on the cusp of turning 18.
It means, overall, around 370,000 children will be eligible.
The UK is in marked contrast with other countries - such as the US and Canada - which have mass vaccinated children aged 12 to 17.
