More than 5 million doses of a Covid-19 vaccine have now been administered in the Republic.
Over 60 percent of adults are now fully vaccinated, while 75 percent have had at least 1 vaccine dose.
Chair of the vaccine taskforce, Professor Brian MacCraith says it's a 'very significant day' in the vaccination programme.
"Over the past number of weeks, we've been hitting typically around 340 to 350 thousand doses per week. Well over 50 thousand per day across four days in every seven. It's really been ramping up again in recent weeks"
It comes on the day that the HSE's vaccination portal opens for another cohort of the population.
25 to 29 year olds can register for a Pfizer or Moderna vaccine from today. However people in this age group can still register with a pharmacy for a Janssen vaccine.
