Plasma Economy
Plasma Economy (Chinese: 血浆经济) was a 1991–1995 plasmapheresis campaign by the Henan provincial government in China, in which blood plasma was extracted in exchange for money. The campaign attracted 3 million donors, most of whom lived in rural China, and it is estimated at least 40% of the blood donors subsequently contracted HIV. The Plasma Economy campaign boomed due to demand by biotech companies, and became a lucrative source of income for middlemen.
