A consultant in infectious diseases says Covid-19 vaccinations should remain voluntary.
The National Public Health Emergency Team is due to consider mandatory vaccination.
However, the Taoiseach and the Chair of the National Immunisation Advisory Committee are among those who say they would oppose such a move.
Latest figures show 90 percent of people over 12 are fully vaccinated.
Infectious Diseases consultant, Eoghan DeBarra, says some restrictions for unvaccinated people could be necessary in the future.
"It might mean that for the unvaccinated that there might be certain areas of work or society that Are too risky to let you be part of, like working with high risk patients.
"How exactly we go about that isn't quite clear to me yet, but we have rates of vaccination that many other countries can only dream of, and we have that by having a society that follows the science and listens to the advice, so we're very lucky."
