I see the Tuskegee example trotted out pretty often and frankly I was ignorant of it. Is this a well known and discussed thing among black people or might it be more about a general distrust of the government, etc. and as you pointed out, being historically under represented in medicine.
I am just guessing a fairly small people asked about Tuskegee would know what it is but maybe it's just me. I am just suggesting maybe asking black people why they don't want a covid vaccine for example and address those issues.
