Ten more COVID-19 mass vaccination centres are opening in England from Monday.
More than 1 million people aged 80 and over will be invited to receive their coronavirus jabs at the hubs.
The 10 sites will join the seven existing centres across the country.
Up to 1,000 GP-led surgeries and more than 250 hospitals are already providing vaccinations.
The government has pledged that every adult in the UK will be offered a coronavirus vaccine by September.
The NHS has said it is vaccinating at a rate of 140 jabs per minute and will start testing 24/7 vaccinations in some hospitals in the next 10 days.
However, it has warned that a new COVID patient is being admitted to hospital every 30 seconds.
England’s initial seven mass vaccination centres welcomed their first patients last Monday.
The 10 new locations include sites in Norwich, Blackburn, York and north London.
Those aged 80 or over who live up to a 45-minute drive away are being offered the choice of having their jab at one of the 17 centres or at a pharmacy site through the national booking service.
Anyone who does not want to travel can wait to be contacted by their GP-led vaccination service or hospital.
About 641,000 invitations were sent out last week and another 380,000 were due to be delivered this weekend.

Another half a million letters will go out this week, NHS England said.
It said the new centres would be able to administer “thousands” of jabs a week, scaling operations up and down according to vaccine supplies.
It will also mean at least one centre is located in each health region and ensures that rural parts of the country like Boston in Lincolnshire and Norwich are within reach of one.
More than 3.8 million people in the UK – including over-80s, care home residents, and NHS and social care staff – have already received their first dose of a COVID-19 vaccine, but from Monday it will be rolled out to the next two priority groups: the over-70s and the clinically extremely vulnerable.
The 10 new centres are:
– Bournemouth International Centre
– Taunton Racecourse in Somerset
– Blackburn Cathedral in Lancashire
– Salt Hill Activity Centre in Slough, Berkshire
– Norwich Food Court in Norfolk
– The Lodge in Wickford, Essex
– Princess Royal Sports Arena in Lincolnshire
– St Helens Rugby Ground in Merseyside
– The park-and-ride at Askham Bar in York
– Olympic Office Centre in Wembley, north London
