Anyone aged 16 and over can now come forward for a Covid-19 booster jab.
From Sunday all of those aged 16 and older who are eligible to receive a booster vaccine can access the service through HSE vaccination centres.
People are being asked to book into a vaccination centre offering jabs to their age group.
Announcing the expansion of the booster programme earlier this week, Minister for Health Stephen Donnelly said that it was important to maintain “momentum”.
However, he warned: “The logistics of this undertaking are not to be underestimated.”
Mr Donnelly added: “As incidence of disease continues to rise, it is vital that anyone eligible for a primary or booster dose vaccine receives that vaccine as soon as possible.”
