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]
The hypothesis that SV40 might cause cancer in humans was a particularly controversial area of research, fuelled by the historical contamination of some batches of polio vaccine with SV40 in the 1950s and 1960s. [4] "Persuasive evidence now indicates that SV40 is causing infections in humans today and represents an emerging pathogen."

The polio vaccines prevented 29 million cases of paralytic polio between 1960 and 2021, compared with a counterfactual world with no vaccines, according to researchers’ estimates.
Poliomyelitis (/ ˌ p oʊ l i oʊ ˌ m aɪ ə ˈ l aɪ t ɪ s / POH-lee-oh-MY-ə-LY-tiss), commonly shortened to polio, is an infectious disease caused by the poliovirus. [1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
A vaccine injection, oral drops or nasal spray is mostly water. Other ingredients are added to boost the immune response, to ensure safety or help with storage, and a tiny amount of material is left-over from the manufacturing process. Very rarely, these materials can cause an allergic reaction in people who are very sensitive to them.
New tests done by the Environmental Working Group have found 21 oat-based cereals and snack bars popular amongst children to have "troubling levels of glyphosate." The chemical, which is the ...
