The head of the HSE says they've been "blown away" by the attendance seen at walk-in vaccine centres yesterday.
Multiple centres across the country reported strong attendance at the walk-ins clinics, with many young people queuing up to receive their first vaccine.
Many centres across the country will be offering further walk-in services today and tomorrow.
The centres are open to anyone over 16 who has yet to receive a first dose vaccine.
HSE CEO Paul Reid says they didn't know what to expect from the first day of walk-in centres.
He said: "We've been blown away by the response yesterday, and the number of people showing up at the walk-in centres.
"We knew it was going to be a good opportunity for people who hadn't had the opportunity to come in to have their vaccination... but particularly the [number of] young people who've come forward has really blown us away."
He said high turnouts were seen in both urban and rural vaccination centres.
Meanwhile, Ireland now has a higher percentage of adults fully vaccinated than the UK.
Taoiseach Micheál Martin said 72.4% of adults have now been fully vaccinated here, compared to 72.1% in the UK.
The vaccine rollout is continuing at great pace.
Today we edged ahead of our nearest neighbours - a brilliant effort by everyone involved.
➡️Ireland: 72.4% of adults fully vaccinated
➡️UK: 72.1% of adults fully vaccinated

The pace of the vaccine rollout globally has changed significantly over the last two months, with the EU now reporting higher rates of vaccination than the likes of the US.
However, many low-income and developing countries are still experiencing low levels of vaccination amid a limited supply of the jabs.
