SV40 is a simian virus introduced into humanity via the polio vaccine. It is a DNA virus isolated in 1960 from contaminated polio vaccines, that induces mesotheliomas, lymphomas, brain and bone tumors, and sarcomas, including osteosarcomas, in lab animals. These same tumor types have been found to contain SV40 DNA and proteins in humans.
