A bit out of context, but not really.
Vaccines are not always safe. There were massive issues with Polio vaccines which were contaminated.
There is no debate among scientists and physicians in government and industry that monkey viruses did, in fact, contaminate many lots of early killed and live polio vaccines used in experimental trials and in mass vaccination programs in the US between 1955 and 1963. There is continued debate about whether monkey viruses, some of which may be yet undetectable by current technology, have continued to contaminate live polio vaccines still grown on the kidney tissues of African green monkeys and administered to millions of children today." - Barbara Loe Fisher, Co-Founder and President, National Vaccine Information Center
Does SV-40 Cause Cancer?
The largest argument has not been whether SV-40 was or still is present in the polio vaccine, but whether or not it truly poses a threat to human health.
The Food and Drug Administration, Centers for Disease Control, and other United States organizations continue to insist that research is inconclusive. It was discovered that SV-40 was the contaminate, and a carcinogen as well.
"Infectious agents have been strongly associated with childhood brain tumors. An excess of central nervous system malignancies occurred in a cohort (a group) of offspring (children) whose mothers were inadvertently exposed to polio vaccine contaminated by Simian Virus 40 (SV40). Medulloblastomas bore the strongest relationship to the contaminated vaccine."

"...we found SV40 DNA sequences in five of six choroid plexus papillomas, eight of eleven ependymomas, three of seven astrocytomas...None of the 13 normal brain tissues were positive for SV40 DNA."

"We decided to test human mesotheliomas and osteosarcomas for SV40 based on...the enormous increase in the incidence of mesotheliomas in the second half of this century which coincided with the inadvertent inoculation of millions of people with SV40 contaminated polio vaccines... SV40 or closely related DNA sequences are present in specific types of human tumors."

"Natural
infections in monkeys by SV40 are usually benign but may become pathogenic in immunocompromised animals, and multiple tissues can be infected. SV40 can replicate in certain types of simian and human cells... SV40 DNA has been identified in some normal human tissues, and there are accumulating reports of detection of SV40 DNA and/or T-ag in a variety of human tumors."

SV-40 Still Found in the Oral Polio Vaccine
In 2001 Attorney Stanley Kops presented his gathered research and information proving that, despite government assurances, modern Polio vaccines still contain SV-40. He had been gathering evidence for a case unrelated to SV-40 and uncovered documentation of continued contamination in the process. Several of his sources included evidence of SV-40 found in cancerous tumors.
