Re: contaminated polio vaccines
What does the SV40 do?
I had both the Salk and Sabin & was born in ‘57; one type was given at the military hospital and the other was given by the local health department.
According to officials it’s not really a concern. Some people think otherwise:
Polio vaccines used in the late 1950s and early 1960s were contaminated with a virus called simian virus 40 (SV40) present in monkey kidney cells used to grow the vaccine. Subsequently, investigators found SV40 DNA in biopsy specimens obtained from patients with cancers such as mesothelioma (lung), osteosarcoma (bone) and non-Hodgkins lymphoma (lymph nodes).

Known to cause tumors in monkeys - Some people think their cancer is related to this.
