[2] David Rasnick received a PhD in chemistry from Georgia Tech in 1978; his thesis was entitled "Affinity Labeling of Metalloendoproteases.
"[3] Rasnick studied proteases in rats and has also written a book about the aneuploidy theory of cancer.
[1][4] Rasnick was a prominent member of the AIDS-denialist movement, which claimed that HIV either did not exist, or did not cause AIDS.
He claimed that HIV was a harmless "passenger virus" incapable of causing any disease.
[5] In association with Matthias Rath, Rasnick traveled to South Africa, a country with one of the highest incidences of HIV/AIDS in the world, where they discouraged HIV-infected individuals from using antiretroviral drugs and instead promoted the use of proprietary vitamin mixes which were claimed to fight AIDS.
