To keep it realistic: what groups do you think would have the smallest chance surviving in a post-apocalyptic, resource-lacking environment? Obviously those who are already facing difficulties and are already oppressed and discriminated. /s

Seriously, though, I second what other comments said: it's probably just the result of authors not thinking about minorities. Not on purpose, just what happens when you don't have to think about something

Interesting analogue fact: that's happening even on the present day: in African countries there are higher rates of anemia, since you get a higher possibility to survive/not develop malaria

Apart from the fact that the article itself says that it has a lower mortality rate than the original one and that those data refer to mices (which makes all the possible difference), as it's obviously not possible nor sensi Al to experiment on humans. Bio and pharm fields require experiments like this one all the time, which can be counterintuitive for people from outside. I'm not really following this exact case, as I don't have time to properly read the paper, but it's likely been done because this will help knowing better some cellular mechanisms, or could be used to develop better vaccines / antivirals... You can be safe knowing that it's a common practice and people who work on that knows how to handle samples. The founds are low enough to not waste them on something unless it's undeniably useful
