Morrisons has said its car parks will be used as coronavirus vaccine centres.
Three stores will help in hosting the roll-out of the jabs from Monday and a further 47 sites being made available to the government.
Morrisons chief executive David Potts said the assets of the company are "at the disposal of the country".
"We'll have three stores operating from Monday 11th January and we have offered up another 47 subject to requirements and availability of the vaccine," he said.
Mr Potts also offered an update on the rules for those shopping the the supermarket and if there are plans to ration products as a third lockdown begins.
"We haven’t got limits on things like pasta and flour and all of those things that people seem to stock up on," he said.
"I think we'll see how the British people handle the news. Clearly we can turn it on fairly sharpish and it's really making sure that everyone has stock."
There had also been fears that some products might not make it to supermarket shelves due to the Covid-19 border closures in December between the UK and France and subsequently over Brexit fears.
But Mr Potts said products continue to arrive without delays.
He said: "On Brexit, the volume crossing the Channel is obviously low at this time of year, so I think any delay on paperwork and process post 31st December is yet to be felt or visible. So far we've not seen any delays."
