Leading immunologist Professor Luke O'Neill has thrown a subtle dig at anti-vaxxers by posting a meme to social media over the weekend.
The Trinity College academic has been one of the main sources of information and hope for people since the virus first hit these shores in March of last year.
But it seems even he is tiring of the rhetoric from those who oppose the use of vaccines, as he took to Twitter on Saturday afternoon with a cartoon illustration about their effectiveness.
Ireland has hit 90% of adults at least partially protected against the virus and 81% of people are now fully vaccinated after another busy weekend in the rollout programme.
However, there are still some who doubt whether they work and protest against their use by the HSE.
Both of these groups were represented in the cartoon.
Ireland's roadmap out of the pandemic is expected to be released towards the end of the month with big changes to restrictions.
It has already been established that Micheál Martin will announce a timetable for the final ending of all restrictions before the end of this month.
This will signal the Government's official ending of the third pandemic lockdown.
A special Cabinet subcommittee on Covid agreed that there will be a “roadmap for the easing or removal of the remaining restrictions” published within weeks.
Over 6.3m vaccines have now been administered in Ireland with public health officials confident that the high level of immunity will help a return to normal.
HSE Chief Paul Reid said on Monday morning: "Today we've now 259 #COVID19 patients in hospital (up from just 40 over 6 weeks ago), 48 of those in ICU. Without vaccines in January we saw hospital cases of over 2,000. But it's a strong reminder to us all to stick with what works, public health measures & vaccines."
