The Taoiseach says the booster vaccine is being rolled out as quickly as possible.
Micheál Martin was speaking at City Hall this evening after he received his booster jab.
The government and HSE apologised after some people were turned away from walk-in vaccine centres during the week due to high demand.
40,000 people received a Covid vaccine at 22 centres around the country yesterday.
Speaking to RedFM News, Taoiseach Micheál Martin says despite some teething problems the combination of appointments and walk-ins is working well:
"I think what we were all endeavouring to do this week, was to get across the sense of urgency attached to getting the booster. And you could fault the HSE for trying to do everything it could to get as many people vaccinated as possible but on the other side, I pay tribute to them for doing what they can, obviously they except there are some issues around systems and that, but fundamentally, the entire effort has been about getting as many people boosted as we possibly can, as quickly as we can."
