I haven't seen the Vox article, but if that's what they said, it's total bullshit and irresponsible journalism, and I'd request that you do your part by not repeating that.
The first kidney donation was in 1954. We have 66 years worth of data--plenty of time for many kidney donors to live out their lives and have the problems caused by kidney donation, so we have a pretty good idea of what the long-term effects of kidney donation are.
We don't know what the long-term effects of coronavirus are because nobody has had it and then lived long term. The first case we know of was in November 2019--five months ago. Vox can't say that "if you're young, the risk of death is about equal to a kidney donation", because we do not know what the risks are. If scientists infected a bunch of 20 year olds with Covid in 2020 and by 2050, 40% of them die of lung cancer before the age of 50, is that something you'd be cool with? Because that might be reality--it's impossible to know.
To be clear, I'm not saying Covid-19 causes lung cancer. I'm saying we cannot possibly know ANYTHING about the long term effect of Covid-19. We shouldn't assume that it causes lung cancer, but we also shouldn't assume it's no more dangerous than a kidney donation. We shouldn't assume, period. So statements like, "if you're young, the risk of death is about equal to a kidney donation" are lies. And I would implore you to not spread that misinformation because it potentially has deadly consequences.
