NHS will be offering a further COVID-19 vaccination over spring to those at greater risk of severe illness from the virus.
People aged 75 and over, those with a weakened immune system and older adult care home residents, will be eligible. This follows advice from the Joint Committee of Vaccination and Immunisation.
Care homes have been prioritised with vaccinations taking place since 3 April by roving NHS teams.
All other eligible groups have been able to book from 5 April using the National Booking Service or NHS App, with the first appointments becoming available on Monday 17 April.
It will be the first time that people will receive their initial invitations through the NHS app, where they can also book, as the NHS continues to expand its technological capabilities.
Text messages and letters will also be sent to those eligible without the app or who do not actively use it.
The NHS is advising those invited, or making a booking, to make sure their appointment takes place at least three months after their last dose.
Anyone who believes they should be eligible for a vaccine but does not get invited can check online. Alternatively, they can self-declare via the National Booking Service and then speak to a clinician on site.
The last spring vaccination appointments will be offered on 30 June.
COVID-19 vaccinations for everyone who was aged 5 on or before 31 August 2022 will also end after that date, following recent advice from the JCVI. After 30 June, the NHS offer will become more targeted to those at increased risk, usually during seasonal campaigns.
