Chief Medical Officer (CMO) Dr. Tony Holohan has said there is limited data on the safety and efficacy of booster Covid-19 vaccines.
Some studies show that booster vaccines improved people’s defences against different variants of the virus, including the Delta variant.
Over 1.5 million doses of booster vaccines have been administered in Israel so far.
Holohan expressed his concern over the limited evidence around booster vaccines in a letter to Minister for Health Stephen Donnelly.
The CMO said people need to be aware that booster vaccines have not been approved by the European medicines regulator.
However, Holohan did give the green light for boosters to be offered to everyone over the age of 80 and everyone over the age of 65 living in residential care facilities.
The HSE is expected to begin rolling out booster vaccines along with the flu vaccine in Ireland from next month.
