evidence: "CDC Admits 98 Million Americans Were Given Cancer Virus Via The Polio Shot," one headline from ushealthmagz.com told readers last weekend. The article gained popularity on Facebook pages like "Cure For Life" and "Medical Marijuana a New Beginning," with some readers suggesting that the "next time someone tells you a vaccine is mandatory tell them to kiss your ass both cheeks" and that "a friend who was a psychic healer … told me that the original polio shot had cancer in it. Most people thought he was crazy." "The CDC has admitted that between 1955–1963 over 98 million Americans received one or more doses of a polio shot," the article claims, "which was contaminated with a cancer-causing virus called Simian vacuolating virus 40 (SV40)." [...] The Children’s Hospital of Philadelphia noted in 2016 that "findings do not support the hypothesis that SV40 virus contained in polio vaccines administered before 1963 cause cancer" and "studies do not show an increased risk of cancers in those who received polio vaccine between 1955 and 1963."
