The Public Health Agency has said there will be enough flu vaccine for people over 65 ahead of the winter flu season.
It said the reassurance follows reports in the media of a “shortage”.
The PHA maintains that there will be a normal total supply of flu vaccines available for anyone who is eligible.
“There will be enough vaccine to ensure that everyone aged over 65 who wishes to be vaccinated, will be vaccinated,” it said.
“There is no shortage.”
The PHA said GP surgeries may have to adapt their flu clinic arrangements due to the staggered introduction of the vaccine.
It acknowledged that this “may present some logistical issues”.
However a statement went on: “The fact remains that offering the best available vaccine to people aged over 65 will help protect them and ultimately help reduce pressures on our health service over winter.”
