Just to be clear to TTT and others, this person was more arrogant than a conspirator. It's a fact of Covid that, for the most part, younger people with no underlying health issues are less likely to die from Covid than the older or sicker. It's sadly easy in those circumstances to assume that you are largely "safe" from Covid if you fall into that age group. He shouldn't have refused the vaccine, and paid the ultimate price for that, but I have some sympathy for his feeling that Covid was not so much a threat to him. I've felt the same way -- and, on a larger scale, it's also not unreasonable. Of the 140,000 deaths attributed to Covid-19 in England and Wales (ONS figures), only 1% are in people aged under 45. This implies an order 1/10,000 chance of dying having caught Covid if you're under the age of 45.** So this man was clearly unlucky. Still, you make your own luck. Taking the vaccine would surely have made a huge difference.
**Again, this is a ballpark figure, rather than an exact value. There's also still some reasons to assume large age variations even within the under-45 age group, to say nothing of other factors like underlying health conditions, sex, etc.
