“What is Simian-40?”
Simian virus 40 (SV40) is a small DNA polyomavirus found in rhesus macaques that can cause tumors in lab animals and was accidentally present in early polio vaccines.
Found between 1955 and 1963 in early inactivated and oral polio vaccines because the virus was grown in monkey kidney cell cultures.
The polyomavirus simian virus 40 (SV40) is a known oncogenic DNA virus which induces primary brain and bone cancers, malignant mesothelioma, and lymphomas in laboratory animals. Persuasive evidence now indicates that SV40 is causing infections in humans today and represents an emerging pathogen. A meta-analysis of molecular, pathological, and clinical data from 1,793 cancer patients indicates that there is a significant excess risk of SV40 associated with human primary brain cancers, primary bone cancers, malignant mesothelioma, and non-Hodgkin’s lymphoma. Experimental data strongly suggest that SV40 may be functionally important in the development of some of those human malignancies.
