Does SV40 cause cancer? Did and does SV40 inadvertendly inside the Polio Vaccine in the late 1950ies and 60ies cause cancer? Does the Pfizer proces 2 SV40 promotor in the Covid Vaccine cause cancer? Is SV40 DNA (or its fingerprints) found inside actual cancer tissue these days? What type of research is performed on it? Does DNA contamination in general cause cancer? I don't know if you're friendly enough to address these isssues. Probably not.
