If you live in England and are aged 16 or over, you can get a COVID-19 vaccine from a walk-in COVID-19 vaccination site without an appointment.
You do not need to be registered with a GP or bring any ID. It might help to bring your NHS number, if you know it.
If you've already had your 1st dose, you need to wait 8 weeks before having your 2nd dose.
Note; you NEED to attend those sites that say they can jab those 16+ years.
