The Department of Health says there has been a significant increase in the number of people seeking to change the date of their second coronavirus vaccine.
It says in recent days, it has received 1,000 requests to reschedule appointments.
Appointments for the second covid-19 jab are usually scheduled after a first appointment is booked, to allow the system to plan ahead for staffing, vaccine supplies and sort appointment slots.
The department is urging people to avoid changing allocated appointment slots where possible.
Patricia Donnelly is the Head of the vaccination programme in Northern Ireland.

She said, “I fully understand that we are all anxious to enjoy a more normal life including an opportunity to enjoy some of the things which have been denied us during the last 18 months.
“However this programme is a massive and highly complex logistical undertaking requiring intense planning.
"The ongoing cooperation of everyone to come forward for their second dose on their appointed date is crucial.
"Getting your second dose is not only vital in providing fuller and longer lasting protection against the virus, but also to enable the thousands of people working so hard managing the roll out to do so as effectively as possible.
“This is why second appointments are automatically generated when a first appointment is booked to allow us to plan ahead, taking into account issues such as supplies of the various vaccines and availability of vaccination slots.
"It is the responsibility of each of us to ensure we are available for our second appointment. So we ask that where possible you avoid making commitments that clash with the date of your second dose – that includes booking flights and hotels – please look for alternative dates.
“Where changing the date of the second dose is unavoidable – please be patient this will not happen immediately. The same people who are running the vaccination centres and organising this very demanding vaccination programme are already busy. So it will take time.
“Any large scale changes could potentially jeopardise the overall roll-out of the programme.
“The success of the vaccine programme in Northern Ireland has been built on an amazing public response which has seen over one million people receive their first dose.
"Their cooperation has played a major part in bringing us to where we are today. It is imperative however that we recognise how important it is, that in order to maintain that progress the full and effective roll out is maintained.”
