I am not sure why you think my statement has anything to do with "base rate fallacy", and your accusation does not offer any substantiation to support your slanderous assertion. My statement was based off of the data being provided by the government of Ontario prior to them ceasing to report their data sets in a convenient manner, no longer providing graphs on their website to show incidence by vaccination type, breakdown of hospitalized/ICU cases over time, etc. (you can still access this information, in a less digestible format from
Datasets - Ontario Data Catalogue). I do understand statistical analysis perfectly well (I have the postgrad credentials to substantiate this statement).
My statement was representative of the hospitalization/death rate (not total number as you seemed to have assumed). I even suggested that the likely cause was the difference in vaccination status by age groups, which I will attempt to explain. Ontario has a very high rate of vaccination and, not surprisingly, vaccine and booster uptake is highest amongst the oldest members of the population... The oldest segments of the population are also overwhelming represented in hospitalizations and deaths from COVID19. While those aged over 60 represent relatively small portion of the total population (3.5 million people), and are almost all vaccinated with at least 2 doses, they represent the majority of total deaths and hospitalizations from COVID19 (in Ontario, at least). In contrast, those under 60 represent a much larger portion of the total population (about 11 million people), are overall significantly less vaccinated as a group (particularly when it comes to booster uptake) and represent a minority of total hospitalizations and deaths.
According to the Public Health Ontario website, the current rate of hospitalization admission for COVID19 of those over aged 80 and over is 25.2 per 100,000, those 60-79 is 4.2 per 100,000, and those aged 40-59 is 0.6. Thus the "rate" of hospitalization for those over 80 is currently about 42 times higher than those aged 40 to 59, in Ontario at least. As for deaths, those 80+ have a current death rate from COVID19 of 4.7 per 100,000, those aged 60-79 have a death rate of 0.4 per 100, 000, 40-59 year olds have a 0.1 per 100, 000 death rate, and 20 to 39 year olds have a 0 per 100,000 death rate. Thus, someone over 80 had a 47 times higher chance of death than someone aged 50-59, at the population level. These are all based off of the last week's reporting and can be found on the Ontario Public Health website (see below).
In Ontario, those aged 80+ have a reported rate of "full vaccination" (minimum of a primary series consisting of 2 doses) of 94.6%, and a single booster (minimum) rate of 86.4%. 40-49 year olds have a booster rate of 54.6%. 30-39 year olds have a booster rate of 46.3%.18-29 year olds have a booster rate of 38.9%. Second booster uptake is 59.6% for those over 80, 13% for those 50-59, and 4% for 18-29 year olds. As for 2nd boosters, those over 80 have a 59.6% uptake rate, compared with a 7.3% uptake for those aged 30-39. I know that I skipped on reporting some age ranges, it was for reasons of brevity, the information is well presented at the link below.
I have not suggested that the vaccines increase risk of hospitalization/death from COVID19, BTW. If you were to take each age group individually, say those over 80, then you are likely to see higher risk of hospitalization/death amongst the unvaccinated portion of that particularly age group. When you expand this data out to the population level though, and only classify people as "vaccinated" or "unvaccinated" (not accounting for age), you find a higher rate of hospitalization/death amongst those who are "vaccinated". The data is misleading because the unvaccinated and unboosted population base leans so far towards younger demographics, which skews the overall rate significantly. I also didn't specify "adult population" when I mentioned rates of risk, so you can assume I am accounting for all age groups combined. These vast differences in risk by age group are, assumedly, the reason why Greece's vaccine mandate only affected those over 60 years of age. In Canada, we put in place workplace mandates that primarily affected those under 60 (those over 60 do not represent a large proportion of the total workforce)... In contrast to both of these measures, Denmark has stopped recommending boosters to those under 50 without other underlying health conditions.
