Ridiculous claim - The SV40 sequence (not a full virus, just a single gene sequence) was used in polio vaccines in the 50s and 60s and has been found in people with mesothelioma and osteosarcoma who never even received the original polio vaccines. The gene sequence is naturally occurring.

But you won't listen, Just keep trying to keep people scared.

Vaccines cause cancer Simian virus 40 (SV40) was present in monkey kidney cells used to make the inactivated polio vaccine, live attenuated polio vaccine, and inactivated adenovirus vaccines in the late 1950s and early 1960s. Recently, investigators found SV40 DNA in biopsy specimens obtained from patients with certain unusual cancers (ie, mesothelioma, osteosarcoma, and non-Hodgkin lymphoma), leading some to hypothesize a link between vaccination and the subsequent development of cancer.181 However, genetic remnants of SV40 were present in cancers of people who had or had not received contaminated polio vaccines; people with cancers who never received SV40-contaminated vaccines were found to have evidence for SV40 in their cancerous cells; and epidemiologic studies did not show an increased risk of cancers in people who received polio vaccine between 1955 and 1963 and people who did not receive these vaccines.181 Taken together, these findings do not support the hypothesis that the SV40 contained in polio vaccines administered before 1963 caused cancers.
