The article says: > the team found that the number of people whose immune system didn’t robustly respond to the vaccine ranged from less than half of one percent of white participants to nearly 10 percent of Asian participants. ... our preliminary results suggest that, on average, people of Black or Asian ancestry could have a slightly increased risk of vaccine ineffectiveness It would be more accurate to say that a person's race may have an effect on the effectiveness of a vaccine but it's still relevant to class them as minorities in the places where the effectiveness is being studied. If a vaccine is being studied in a population of 40000 and only 100 of those people are black, you won't be able to learn as much about the vaccine's effects on people of a certain race because of the low sample size. It's of course relevant for those in countries where those races are majority and more studies need to be done in those places as well.
