More than 18,000 people have attended walk-in vaccination clinics this weekend, HSE CEO Paul Reid says.
Half of those attending are teenagers aged 16-17, while 64% have been aged 19 or under.
However, Mr Reid said people of all ages have been attending the clinics.

Walk-in vaccination centres are continuing to operate today, with vaccines available without an appointment at more than two dozen sites across the country.
Meanwhile, the latest figures show around 87% of adults in Ireland have had at least one dose of a vaccine.
73% of adults are now fully vaccinated.
Vaccination task force chairman Brian MacCraith said 2.1 million doses had been administered over the last six weeks alone, including 1.54 million in July.
On Newstalk Breakfast earlier, UCC Professor Liam Fanning said the walk-in vaccination centres have been a "resounding success", and should absolutely be organised again in the future.
He noted the August bank holiday was a particularly good time to have the walk-in clinics, as people may have a bit more time to attend.
