what your suggesting… as I read it I couldnt help but think of Arkansas prison inmates that were used as plasma donors.

bear in mind that if plasma is only the white blood cells. the kind that are the only ones of interest regarding matters of hiv and aids.
come to think of it this is from that sauce
Many pharmaceutical companies ceased buying prison plasma after a December 1982 warning from the Food and Drug Administration (FDA) that prisoners were more likely than the general population to be infected with the AIDS virus.
but that year dont sound right… the early uears people were screaming its the gay cancer cuz no one really knew wtf. I was a kid, but i still remember eddie murphys stand up bit about the shit.
so i just checked for "when was hiv identified"
and got this
1982
In June 1982, a group of cases among gay men in Southern California suggested that the cause of the immune deficiency was sexual and the syndrome was initially called gay-related immune deficiency (or GRID).6
Later that month, the disease was reported in haemophiliacs and Haitians leading many to believe it had originated in Haiti.7 8
in 1982 nothing about cdc concluding blood contact as a vector. ergo no reason to panic correctional system about their experiments / pharma partnerships. they are just getting to wrap heads around it.
according to same site it wasnt until late 1983 that they felt confident in having identified transmission methods.
