People who have a weak immune system, also called immunocompromised, can now get a booster (4th) dose. People in this group were offered an additional dose of the COVID-19 vaccine last year, and can now get a booster dose if it has been 3 months since their additional dose. If they had the Pfizer, Astrazenaca or Moderna vaccine, this booster will be their fourth vaccine dose. You can find more information from the HSE here.
