Up to 300,000 doses of the Covid-19 vaccine were administered last week with a similar number of doses expected to be delivered next week according to the HSE.
Meanwhile, those aged 45 to 69 can still register for the vaccine while those aged 40-44 are awaiting an announcement on when they can resister.
As a result of the cyber attack on the HSE, people who were in close contact with a confirmed case or have symptoms of Covid-19 can attend any test centre without an appointment.
Those who attend these appointments are asked to bring photo ID and a mobile phone number, however, it has been noted that delays are to be expected as a result of the cyber attack.
The HSE also stated that most appointments are going ahead but many x-ray appointments are cancelled.
