The NHS is hoping to drive the uptake of coronavirus vaccines by sending people text messages and reminders.
Texts will now be sent to 40,000 unpaid carers and almost 400,000 people aged 55 and over.
The messages will include a weblink so the person can reserve an appointment at one of more than 300 vaccination centres or pharmacies across England.
There are currently two vaccination centres in Milton Keynes - one at Milton Keynes Hospital, and another at Saxon Court. Numerous GP surgeries and pharmacies across the city also offer the vaccine.
These text message reminders will then be sent every two to three weeks to encourage people to get their vaccine if they have not taken up the offer.
If the move proves successful, younger people can expect to receive texts ahead of official NHS letters landing on doormats.
Some GP-led and hospital vaccination services are already using text messages to invite people for a vaccine.
Health Secretary Matt Hancock said: "Our vaccination rollout is moving at a blistering speed and these text alerts will increase the pace by making it even easier for people to get booked in for their jab.
"Thanks to the tireless work of our NHS staff, two in every five adults now have some degree of protection.
"Vaccines are the best way of securing our long-term freedom and will save thousands of lives, so I urge everyone to take up the offer when the text pings into their phone."
