The HSE is urging people to check if they are up to date with their Covid-19 vaccine boosters.
They are particularly urging those who are over 12 with an underlying health condition or who are immunocompromised, those who are over 50, and, healthcare workers to get a booster.
It comes as people will be making plans to meet up around Christmas, with the HSE encouraging people to get boosted in order to help protect those who may be more vulnerable to Covid.
