In a post on Twitter, he said 60% of cases in ICUs are not vaccinated, adding, "this is striking when only 9% of adults (18+) haven't been fully vaccinated".
Thankfully #covid19 hospitalised cases now down to 272. In ICU today 60% of cases are 50yrs+ & 40% aged 19-49. However 60% of cases in ICU are non vaccinated. This is striking when only 9% of adults (18+) haven't been fully vaccinated. Vaccinations do protect stronger. @HSELive— Paul Reid (@paulreiddublin) September 22, 2021
