Interestingly enough, the stats here are that the double vaxxed shrug it off, unless they have immunity problems. According to our healthcare folks, most of the dying ones are unvaxxed. We're assured that even if efficacy is low, you're about 99% less likely to be hospitalized.
But I personally know plenty of single vaxxed people who died. And my symptoms from the second vaccine (pfizer) were nasty enough for a fake virus, I can't really imagine it being light for the real thing. I feel like there's some missing context.
