IRISH VAX: GET VAXXED, GET COVID, GET SICK

What are the chances of getting vax and getting COVID, and not getting vaxxed and getting COVID? 
About 50-50
The Irish Times on 10 September reported, based on 323 COVID-19 patients hospitalized at the time of the study (at the end of August), that slightly more than half had been fully vaccinated. 
Also, one-sixth of the COVID deaths since April have been ascribed to “breakthrough” infections in fully vaccinated patients; such breakthroughs also account for more than 25 percent of ICU admissions since July.
The article claims that the rising number of breakthrough cases is a function of the greater number of vaccinated persons in the population (now about 90 percent), and that the majority of COVID hospitalizations now involve vaccinated persons. 
It also claims that vaccination has drastically reduced the overall number of infections, as well as the severity of those infections. 
TRENDPOST: Before drawing conclusions from these numbers, however, Trends Journal advises keeping several things in mind: One is that some 72 percent of ICU patients since late June had some underlying condition; another is that 70 percent of those hospitalized are over 50. 
And yet another is that the definitions used for “vaccinated” vs. “unvaccinated” are similar to what the CDC has done—not counting people as being fully vaccinated until some two weeks after their jab or jabs (see “CDC MANIPULATES DATA TO SUPPORT NARRATIVE (AGAIN),” 14 Sep 2021). This tends to make the statistics somewhat less than conclusive.
