Minister for Health Stephen Donnelly has confirmed that the HSE’s COVID vaccine portal will open to the 25-29 age cohort tomorrow, July 16.
In an announcement, Minister Donnelly said, "Calling all 25–29-year-olds. You can register for an mRNA vaccine from TOMORROW".
Those who register through the portal will receive a Pfizer or Moderna mRNA vaccine.
To register for the vaccine, people will need their PPS number, Eircode, a mobile phone number and an email address.
If you do not have all four of these or would prefer not to register online, you can call HSELive on 1850 241 850.
People aged 18-34 can also register for a one-shot Janssen vaccine with a pharmacy. However, this is subject to supply.
It is expected that the HSE will implement an opt-in system that will allow people aged 18-34 to register for an AstraZeneca or Janssen vaccine through the online portal.

Last night Minister Donnelly announced that 4.85 million doses of the vaccine had been administered.
In a tweet, he said, "Update on our Vaccination Programme.
“>4.85 million doses administered (not all Janssen doses in pharmacies recorded at this time)
“>70% of adults have had at least one those And we’re heading for 60% with full vaccination.
“Thanks to all the vaccinators.”
As of Tuesday, over 2.6 million people in Ireland have now received at least one dose, with more than 2.1 million people fully vaccinated.
The government have attempted to accelerate the vaccine roll-out as the spread of the Delta variant continues.
Data has shown an apparent increase in incidence of disease across the country.
Public health officials confirmed 783 new cases last night, with 72 people currently in hospital with Covid and 20 patients in intensive care.
Speaking at last nights briefing, deputy chief medical officer Dr Ronan Glynn said: "There is no question that the delta variant is having a considerable impact of transmission of Covid-19.
He added: "If you have any symptoms of a cold or flu, it is vital that you isolate immediately and arrange a test."
Dr Glynn said 626 cases reported in the last two weeks were associated with travel as it represented more than one in 10 cases.
He said, “A significant number of our positive cases over the past fortnight have been in Spain in the previous days. Spain, Britain and Portugal are particular high numbers.”
Unvaccinated people are urged to remain cautious and adhere to public health guidelines.
