All 16- and 17-year-olds in England will be able to get a first Covid jab by Monday 23 August.
The Government decision gives teenagers two weeks to build up partial immunity before school starts in September.
About 100,000 eligible teenagers will receive texts inviting them to book at one of more than 800 local centres. NHS England also has a website to help locate the nearest available walk-in centre. Further sites will come online over the coming days and weeks.
Children aged 12 to 15 who are clinically vulnerable to Covid-19, or who live with adults at increased risk, will also be entitled to the vaccine. This group cannot attend walk-in centres. The NHS will invite them for a first dose by 23 August, ahead of the new school year.
