These recommendations are made recognising the uncertainties regarding the trajectory of SARS-CoV-2 infections and on a precautionary basis to protect those most at risk of a severe outcome. They are based on current evidence and will be reviewed when more information becomes available. See the prior recommendations for primary and first booster vaccination.

1. Efforts to increase primary and first booster vaccination uptake should remain a public health priority. mRNA vaccines (Comirnaty and Spikevax) are the preferred vaccines for use in Ireland.

  • Those aged 12 years and older, including those pregnant or breastfeeding, should complete a primary course and receive a booster vaccine (total of three doses)
  • Those aged 5-11 years should complete a primary course (total of two doses)
  • Those with immunocompromise associated with a sub optimal response to vaccines at the time of their primary or booster vaccination:
    • aged 12 years and older should complete a primary course, an additional dose and a booster vaccine (total of four doses)
    • aged 5-11 years should complete a primary course and an additional dose (total of three vaccine doses)

2. Those who have a contraindication to or who decline a primary course or booster dose of an mRNA vaccine should be offered a non-mRNA vaccine.

3. Those who have had previous SARS-CoV-2 infection should complete their primary and booster vaccination to optimise their protection.
