I quote from their abstract: "...among a convenience sample...39% of people on gender-affirming hormones"
convenience sample means "I asked my friends on social media"
And 39% on gender-affirming hormones! Yes, I know trans is all the rage now, but it's not 39% of the population! It's a highly biased sample.
What exactly are they suggesting. That the vaccine was engineered to have a more negative effect on non-white women?
Yes, a persons race does have an impact on outcomes regardless of economic factors.
Recently, a few conferences talked about us trying to ignore race and instead move to genetic haplogroups as (in essence) race was used just to get at these genetic conditions (from their haplogroup). Its too early to say if that will happen. I am guessing eventually yes but not in our lifetime.
Hope this helps.
I certainly wouldn't.
I hate to be so cynical, but it's hard not to be.
