Long queues have formed at vaccine clinics in the main cities again this weekend -- with some waiting for up to an hour.
Nationwide, over 30 walk-in clinics are open today and tomorrow, where healthcare workers and over-60s can get their third jab.
The HSE says the queue at City Hall is resulting in a 35-minute wait at City Hall, while at Citywest in Dublin there is a 60 minute wait, and a 45 minutes delay at the Galway Racecourse clinic.
City Hall is open for walk-ins for the first or second jab for everyone aged 12 years or over, and for healthcare workers and people in their 60s who would like to get a booster shot, until 3 o'clock today, and between 9am and 3pm tomorrow.
Close to 1 million people have received an additional dose so far.
