City Hall will be open for walk-ins from 1pm to 4pm today.
Individuals aged 16 or older can get their first or second Pfizer doses at the walk-in clinic.
People hoping to get their second dose today must have had their first dose at least 21 days ago - specifically before the 1st August.
They are asked to bring their vaccination cards with them.
City Hall will also be open for first and second dose walk-ins tomorrow between 11am to 2pm.
Damian McCallion is the HSE's national lead for the vaccination rollout - he says it's important to double check clinic information online:
"Because we're running both dose one and dose two, it's really important that people would check HSE.ie for information, in terms of the date of the particular clinic that they're looking to visit, and also in relation to the particular vaccines. So some of the clinics are for Moderna, for example, others are for Pfizer, so it's really important that people would check HSE.ie."
