Vaccines usually cause people to get the disease they are injected with, that is one of the main purposes of vaccines....So, No, polio vaccines cause polio, and people have been paralyzed on many occasions by the vaccine itself.....

"In fact, according to CDC figures, every
case of polio in the U.S. since 1979 was caused by the oral polio
vaccine [36]. Authorities claim the vaccine was responsible for
about eight cases of polio every year [46]. However, an independ-
ent study that analyzed the government’s own vaccine database
during a recent period of less than five years uncovered 13,641
reports of adverse events following use of the oral polio vaccine.
These reports included 6,364 emergency room visits and 540
deaths (Figure 3) [47,48]."

"There is another polio vaccine risk--"a ticking time bomb," according to Harvard Medical School professor Ronald Desrosier--that public health officials are reluctant to discuss frankly. What is it? The polio virus that is used in both Wyeth-Lederle's oral vaccine and Connaught's injected version is grown on monkeys' kidney tissue. "The danger in using monkey tissue to produce human vaccines," says Desrosier, "is that some viruses produced by monkeys may be transferred to humans in the vaccine, with very bad health consequences." Desrosier acknowledges that you can test monkeys before using their tissue and screen out those carrying harmful viruses. But he warns that you can test only for those viruses you know about--and that our knowledge is limited to perhaps "2% of existing monkey viruses."

The danger is not hypothetical. In 1959, Ben Sweet, a 35-year-old scientist at Merck, the pharmaceutical giant, discovered that a previously undetected monkey virus called SV-40 had contaminated oral polio vaccines given to Americans for the prior five years. When testing revealed that SV-40 was a cancer-causing agent, producing tumors in hamsters, the FDA and manufacturers agreed that rhesus monkeys would no longer be used in vaccine production. Instead, the manufacturers would use African green monkeys, in whom the virus was easier to detect and screen out. But federal health officials knew the potential problem was enormous because, by then, as many as 30 million Americans had received both injectable and oral polio vaccines contaminated with SV-40. "Seeing that viruses could jump species really opened our eyes," says Sweet. "Merck stopped all polio vaccine development cold."

Even though SV-40 was being screened out, scientists such as John Martin, a professor of pathology at the University of Southern California, warned that other monkey viruses could be dangerous. But government officials rebuffed Martin's attempt to research those risks back in 1978 and again in 1995 when he was denied federal funding and vaccine samples he needed to investigate the effects of simian cytomegalovirus (SCMV), an organism that his studies indicate causes neurological disorders in the human brain. The virus has been found in monkeys used for polio vaccine production. Similarly, Cecil H. Fox was also rebuffed when, as a senior scientist at the National Institutes of Health in 1988, he asked to examine archived lots of polio vaccine to learn whether they contained simian immunodeficiency virus (SIV), which has been screened out of polio vaccines since 1987 because of potential human impact. "The resistance of those in authority to face the issue of prior vaccine contamination is particularly unfortunate," says Martin, "because research establishing a viral cause for neurological disorders or cancers can lead to effective antiviral treatments."

Beginning in 1992, scientific evidence supporting fears about prior contamination began to mount. Studies suggested that SV-40 was a catalyst for many types of cancer, not only in people who had received polio vaccine containing the virus but in their children as well."
