1 In the 1950s, rhesus monkey kidney cells, which contain SV40 if the animal is infected, were used in preparing polio vaccines. 2  Because SV40 was not discovered until 1960, no one was aware in the 1950s that polio vaccine could be contaminated. SV40-contaminated oral polio vaccines were produced from early 1960s to about 1978 and were used throughout the world. 2  In the 1950s, rhesus monkey kidney cells, which contain SV40 if the animal is infected, were used in preparing polio vaccines.
