The Irish Blood Transfusion Service hopes smaller clinics in local communities will reopen very soon.
Freedom of Information figures show different levels of blood donations across the country.
Overall there was an increase of over 4,000 last year, bringing the total number of donations to almost 131,000.
However, Longford had the fewest donations at just 586 with Leitrim the next lowest.
Stephen Cousins, National Donation Services Manager, says they were restricted in what venues they could use in the pandemic.
"When Covid hit, we lost a lot of our venues such schools, community centres, hotels.
"When we brought in social distancing it meant that we couldn't go back to certain venues.
"We ended up going to centralised venues, where we would set up in a hotel for a week and we would call people from all around that county to that venue, which wasn't very convenient for a number of donors.
"We are hoping in the next number of weeks to get back into the smaller clinics and the community centres for blood donations."
