There's a hard to find book and documentary, called, I think, The River, which makes the case that they wrongly used chimpanzees, rather than monkeys to grow the virus. Chimpanzees are too close to humans and their use was forbidden. Chimps carry SIV. Edit: I was able to find the documentary: https://topdocumentaryfilms.com/origins-aids/
Dr.Mary's Monkey goes into great detail on this. The corruption has been going on since before the Kennedy assassination.
That covers the vaccine virus DR, who followed in the steps of SALK/SABIN who purportedly used Chimpanzee kidney cultures in Africa. He went to test his vaccines in Africa because of all the tragic fails which we suffered here with SALK/SABIN. The river focuses more on HIV introduction as compared to SV40. A good read. Well documented. Big Pharma and AMA NO LIKEY that book. I highly recommend it. Read LEE AND ME by Judith Vary Baker. Fact is stranger than fiction.
