Irish pharmacies have administered 100,000 COVID-19 vaccines, with more than 86% going to people in younger age groups.
The Irish Pharmacy Union (IPU) says up to 10,000 vaccines are being administered each day in pharmacies.
Pharmacies began administering vaccines in mid-June and have experienced huge demand for vaccines from those aged 18-34, which began on July 5th.
Appointments can still be made through pharmacies for a one-shot Johnson & Johnson jab as more supply is expected in August.
The head of the IPU, Darragh O'Loughlin, says there is very little hesitancy about getting a vaccine here.
"Ireland is different to what they've seen in other countries, because there's been very little reluctance evident among younger people.
"We've had them clamouring for vaccines, and I'd say at this stage most vaccine doses available in pharmacies have had about 10 young people looking for them.
"Today we have reached 100,000 vaccinations; and considering we only took the service off in earnest two weeks ago, it's evidence of a real enthusiasm among young people".
Mr O'Loughlin says they would like to get access to more Pfizer doses.
"Over 800 pharmacies [are] doing Janssen vaccines, there are only 350 pharmacies that have Pfizer vaccine.
"The HSE only supplied it to 350 pharmacies, and they're mostly in communities that are distant from a vaccination centre.
"We would love to see more pharmacies having access to the Pfizer vaccine, particularly because there's a dip in supply of the Janssen vaccines.
"But the vast majority of the vaccines being administered in pharmacies up til now has been Janssen".
As of Monday, pharmacies had administered 100,335 vaccines nationwide - and since the service was opened to younger people, that number has been growing by 5,000 to 10,000 vaccines per day.
While over 86,000 of the vaccines administered in pharmacies have gone to the younger age cohort.
The IPU is urging anyone still waiting for an appointment to be patient, as increased supply of the Janssen vaccine is expected from early August.
HSE figures show more than 5.1 million doses have been administered nationally through pharmacies, GPs and the HSE portal.
