Walk-in vaccination centres are reopening across the country this weekend.
Most of the clinics will be offering first doses of the Pfizer COVID-19 vaccine, while some will also be offering second doses.
A smaller number of the clinics will offer the Moderna jab.
Second doses will be available only for people who received their first Pfizer dose over 21 days ago or their Moderna jab over 28 days ago.
Centres are operating in over a dozen counties over the course of the weekend, with full details available on the HSE website.
Damian McCallion, the HSE's national lead for the vaccination rollout, says they're encouraging as many people as possible to come forward.
He said: "Part of the objective of this weekend is to really give people more opportunity to be vaccinated."
HSE CEO Paul Reid yesterday told RTÉ that health officials are now looking to 'close the gap' between first and second doses.
The most recent figures show that over 90% of adults have received at least one dose of a vaccine, with around 84% now fully vaccinated.
Yesterday, CMO Dr Tony Holohan said it's vital "for as many people as possible to come forward" for a vaccine.
It comes amid warnings of a high level of COVID-19 transmission in the community, with over 2,000 new cases reported again yesterday.
Dr Holohan said: "COVID-19 vaccines are very effective against severe illness from COVID-19 and are protecting people from needing care in hospital and ICU.
"While it is possible for fully vaccinated individuals to become infected with COVID-19 and pass the virus on to others, vaccines also remain effective in significantly reducing this risk."
