Currently, the deaths-per-100k of the unvaccinated vs vaccinated population is twelve times higher.

Remember: if 100% of your population is vaccinated, then 100% of your hospitalizations and deaths will be in vaccinated people.

Depending on how we define severe COVID you link is showing between 36% and 44% of the severe COVID patients at the hospital are vaccinated.
That's similar to what they have seen in Israel. As of about a month ago they were seeing about 60% of their severe cases were in vaccinated people.
Sounds pretty bad for vaccines, right? It does until you remember Simpson's paradox and take a finer look at the data [1]. It turns out that the Israel data showed in each age group efficacy against severe COVID ranging from 81.1% to 100%, with above 92% in all the 10 year age groups under 60 and still above 88% is the 10 years groups through 80.
It is very likely a similar thing is going on at the hospital whose data you linked to. That's been the case for every place I've come across in the US that published breakdowns of the stats by age group.

There is no doubt about vaccine efficacy. However it all depends. On your age, on your illnesses, on strains of virus. Who knows what you will get in 2 years.
So people who say that "pfft it is only 2% chance and only if you get" are just denying it.
You will get COVID. Hopefully you get it after a few years when there are not only vaccines but drugs widely available.
