A quarter of young teenagers in England have now had a first dose of COVID-19 vaccine.

An estimated 25.3% of 12 to 15-year-olds had received a jab as of 3 November, up from 20.1% a week earlier, the latest figures show.

Take-up of vaccines among teenagers has picked up pace in recent days, after jabs became widely available at vaccination centres across England.

Previously, first doses were being delivered mostly in schools.

England still lags some way behind Wales and Scotland, however.

Some 45.9% of 12-15 year-olds in Wales are estimated have received a first dose, along with 54.7% in Scotland.

Figures for take-up are calculated slightly differently in the three nations, with England and Wales using age groups based on their national immunisation databases and Scotland using population estimates from the Office for National Statistics.
