The online booking portal for Covid-19 vaccines has opened today for those aged 25-29-years-old.
Anyone looking to apply for their vaccine can do so here.
Applicants will need their PPS number, their Eircode, a mobile number and an email address.

Those who register through the vaccine portal will be offered an mRNA vaccine, such as a Pfizer or Moderna vaccine.
Those aged 18-34-years-old are also able to register at a participating pharmacy to receive the single-shot Johnson and Johnson vaccine.
