On average, 300,000 people are being vaccinated, weekly.
The vaccine portal for those aged 35-39 will open on Sunday.
The Health Minister has confirmed the news saying people aged 39 can register first and it will work downwards based on age.
The Government says over 300,000 people are currently being vaccinated every week.
The HSE says vaccinating people in their thirties will take longer than previous age groups.
Almost 3.5 million doses of the vaccine have so far been issued, with 31 per cent of the adult population fully vaccinated.
HSE CEO Paul Reid says there are two reasons it will take longer to vaccinate those in their 30s.
