People could receive 'multiple invites' for coronavirus jabs due to a cross-over between national and local vaccination programmes.
A GP practice in South Manchester has warned patients that they could be contacted more than once in the early stages of the vaccination roll-out.
Barlow Medical Centre on Wilmslow Road published a statement on its website stating: "We will be running our vaccination programme alongside the national vaccination campaign so you may receive multiple invitations, please book an appointment where and when this is the most convenient for you.
"The most important thing is that you get vaccinated!"
The surgery has also warned that it may not 'operate as normal for many months' due to staff being diverted to the vax programme.
Practice bosses said a 'significant number' of staff would be working 'round the clock' to get the vaccination process up and running.
Citing soaring demand due to winter pressures and an 'exponential rise' in Covid cases, along with staff illness, shielding and self-isolating, the practice said the added responsibility of 'designing, implementing and staffing the vaccination programme' means the service will change 'for many months'.
Encouraging patients to exercise 'self care' and 'self-referral', the statement asks for understanding and cooperation.
It adds: "Of course we are here for you and if you are worried at all about anything we will be happy to help but please consider alternative options first."
More than 600,000 people age 80 and over have started to receive the coronavirus shot at vaccine centres around the country.
The centres are manned largely by GP practices, which are pooling staff on a rota system.
On Sunday the Government announced plans to offer every adult in the UK a jab by autumn amid a huge surge in infections.
Health secretary Matt Hancock has also said that officials were 'on track' to reach the target of inoculating about 15m people in the most vulnerable groups by mid-February.
