There are 73 new positive cases of COVID-19 in Northern Ireland.
Meanwhile, over 1000 people have asked to reschedule their second COVID-19 vaccine in recent days.
Patricia Donnelly, Head of the Northern Ireland Vaccine Programme, said any large scale changes could potentially jeopardise the overall roll-out of the programme.
Second appointments are automatically generated when a first appointment is booked to allow forward planning, taking into account issues such as supplies of the various vaccines and availability of vaccination slots.
