Have polio vaccines ever been contaminated with other viruses?
Yes. Some of the first Salk polio vaccines and Sabin polio vaccines were contaminated with SV-40, a virus found in some species of monkey. SV-40 is not related to HIV. Studies have shown no increased rates of disease among persons who received that vaccine. Modern vaccines do not contain SV-40. The Sabin vaccine seed strains, which are used to make modern OPV, have been repeatedly tested using very sensitive assays and shown to be free of any virus contamination.

The polio vaccine saved millions from permanant disability and thousands from death. I think you "know" far less then you think.
