 | | The small DNA-containing polio viruses (simian virus 40 [SV40], JC virus, and BK virus) are known to infect human beings, to have cancer causing potential, and to be associated with some human cancers. |
 | | Inactivated and live, attenuated forms of the polio vaccine were prepared in primary rhesus monkey kidney cells, some of which were from animals naturally infected with SV40 -- a virus that was unknown at the time. |
 | | In the USA, vaccine lots received by about 20 states are estimated to have contained 075-097 mL contaminated vaccine per child, lots from about 15 states were thought to have contained 001-074 ml contaminated vaccine per child, and about 15 states were believed to have received lots that were free from SV40. |
