From 1955 to 1963, an estimated 10-30% of polio vaccines administered in the US were contaminated with simian virus 40 (SV40). The virus came from monkey kidney cell cultures used to make polio vaccines at that time. Most of the contamination was in the inactivated polio vaccine (IPV), but it was also found in oral polio vaccine (OPV). After the contamination was discovered, the U.S. government established testing requirements to verify that all new lots of polio vaccines were free of SV40.
Because of research done with SV40 in animal models, there has been some concern that the virus could cause cancer in humans. However, most studies looking at the relationship between SV40 and cancers are reassuring, finding no causal association between receipt of SV40-contaminated polio vaccine and development of cancer.
No vaccines used today contain SV40 virus.

The SV40 mutation exists as part of the critical Hek 293 cells. Read more above.
Thanks. This is great reading.
You should read into the creator of the Hek line. Still living today...

His specialty is viral tumor research.
His research can be said to have enhanced modern pharma understanding of the cause and effect of tumors with a viral vector.
Bookmark and study. I love this type of info.
Just to note, Frank l Graham has a very interesting nondescript past considering he was part of a cornerstone to virology.
