Ayup. Had a close relative like this--he was about 10 years younger than me and still has a teenager. He got Delta and wound up on ECMO. He didn't make it.
All because anti-vax was part of his social identity.
And it's not like he didn't know. I got Covid Original Flavour(tm) and loudly told everybody around me how much it sucked (it was basically the 3rd sickest I've ever been in my life) and all the side effects I got from it.

(I am not taking a position on the findings of that study, just providing a link as a reference.)
Keep in mind the metric they use (IRR - incident rate ratio) is a ratio, not a percent. So an IRR of 15 means 1500% more events. Table 2 lays out everything quite nicely. To see it you need to click on figures/tables and scroll down a bit.
