City Hall will run between the hours of 10 and 2 and Bantry Primary Care Centre is offering walk in appointments from 9.15 to 12.15.
They'll allow people over-12 to get their first or second dose of a Pfizer or Moderna jab.
Over 7 million vaccines have been given out so far - with over 3.5 million people fully vaccinated.
Former HSE director-general, Tony O'Brien, is encouraging people to attend the walk-in centres today.
"If anybody does have any concern about the vaccine there's lots of information on the HSE's website. And these vaccines have been so widely use now that there's very strong evidence about their effectiveness and safety. So while I understand that people can always be had some degree of hesitancy about taking a vaccine. Now is the time to really consider, if the right time is to have that vaccine."
