SV40 is an abbreviation for simian vacuolating virus 40 or simian virus 40, a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that is found to cause tumors in humans and animals, but most often persists as a latent infection.

2025年1月4日 · A recent peer-reviewed study highlights the presence of SV40 cancer virus fragments and DNA contamination in mRNA COVID-19 vaccines, raising new questions about vaccine safety.

SV40 was present in cancers of people who either had or had not received the polio vaccines that were contaminated with SV40. SV40 has not been present in any vaccine since 1963. People with cancers who were born after 1963, when SV40 was no longer a contaminant of the polio vaccine, were found to have evidence for SV40 in their cancerous cells.

2007年7月9日 · Simian virus 40 (SV40) is a monkey virus that was administered to human populations by contaminated vaccines which were produced in SV40 naturally infected monkey cells.

Simian virus 40 (SV40) is a virus that infects several species of monkeys and typically does not cause disease in them. The virus was discovered in 1960 in rhesus macaque

2024年7月31日 · 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.

SV40 was the 40th virus found in rhesus monkey kidney cells when these cells were used to make the polio vaccine. SV40 stands for Simian Virus 40. This virus contaminated both the Inactivated Polio Vaccine (IPV) created by Dr. Jonas Salk and the Oral or “Live” Polio Vaccine (OPV) created by Dr. Albert Sabin.

Since its discovery, simian virus 40 (SV40) has been one of the most intensely studied animal viruses. The molecular biology of SV40 has led to seminal discoveries in the fields of transcription, DNA replication, and oncogenic transformation . Over the last decade, provocative evidence has accumulated that suggests that SV40 may be a human ...

Vaccine contamination with Simian vacuolating virus 40, known as SV40 occurred in the United States and other countries between 1955 and 1961.. SV40 is a monkey virus that has the potential to cause cancer in animals and humans, although this is considered very unlikely and there have been no known human cases. [1] Soon after its discovery, SV40 was identified in …
