Yet again, you are posting information that is way out of date. There is a reason why there are such stringent regulations on vaccine approvals and monitoring (like it says in your citation above, "On March 25, 1961, the federal regulations that controlled the production of oral poliovirus vaccine were amended."). They weren't even THAT unsafe back then, but enough hysteria created legislation that over-corrected for that problem, to our benefit for sure.Arlen wrote: Let's all trust the government and the vaccine developers!
In 1960, it was determined that the rhesus monkey kidney cells used to prepare the poliovirus vaccines were infected with the SV40 virus (Simian Virus-40). SV40 was also discovered in 1960 and is a naturally occurring virus that infects monkeys. In 1961, SV40 was found to cause tumors in rodents. More recently, the virus was found in certain forms of cancer in humans, for instance brain and bone tumors, pleural and peritoneal mesothelioma, and some types of non-Hodgkin's lymphoma. However, it has not been determined that SV40 causes these cancers.
SV40 was found to be present in stocks of the injected form of the polio vaccine (IPV) in use between 1955 to 1963. It is not found in the OPV form.

SV40 stands for Simian Virus 40
Upon the discovery that SV40 was an animal carcinogen that had found its way into the polio vaccines, a new federal law was passed in 1961 that required that no vaccines contain this virus. However, this law did not require that SV40 contaminated vaccines be thrown away or that the contaminated seed material (used to make all polio vaccines for the next four decades) be discarded. As a result, known SV40 contaminated vaccines were injected into children up until 1963. In addition, it has been alleged that there have been SV40-contaminated batches of oral polio vaccine administered to some children until the end of the 1990's .

http://www.ncbi.nlm.nih.gov/pubmed/16963733An unknown proportion of formalin-inactivated poliovirus vaccine lots administered to millions of US residents between 1955 and 1963 was contaminated with small amounts of infectious simian virus 40 (SV40), a polyomavirus of the rhesus macaque. It has been reported that mesothelioma, brain tumors, osteosarcoma and non-Hodgkin lymphoma (NHL) contain SV40 DNA sequences and that SV40 infection introduced into humans by the vaccine probably contributed to the development of these cancers. The Immunization Safety Review Committee of the Institute of Medicine (IOM) reviewed this topic in 2002. The present review of recent studies showed that the earlier results describing the recovery of SV40 DNA sequences from a large proportion of the above tumors were not reproducible and that most studies were negative. SV40 sero-reactivity in patients with the suspect tumors was no greater than that in controls. In epidemiologic studies, the increased incidence of some of the suspect tumors in the 1970s to 1980s was not related to the risk of exposure to SV40-contaminated vaccines. In summary, the most recent evidence does not support the notion that SV40 contributed to the development of human cancers.
http://www.ncbi.nlm.nih.gov/pubmed/16288015Many studies have attempted to assess the relationship between the potential exposure of humans to SV40 and cancer incidence. Reports of the detection of SV40 DNA in a variety of cancers have raised serious concerns as to whether the inadvertent inoculation with SV40 has led to the development of cancer in humans. However, inconsistent reports linking SV40 with various tumor types has led to conflicting views regarding the potential of SV40 as a human cancer virus. Several recent studies suggest that older detection methodologies were flawed, and the limitations of these methods could account for most, if not all, of the positive correlations of SV40 in human tumors to date. Although many people may have been exposed to SV40 by polio vaccination, there is inadequate evidence to support widespread SV40 infection in the population, increased tumor incidence in those individuals who received contaminated vaccine, or a direct role for SV40 in human cancer.
So NOT until the end of the 1990's as claimed in the link at the top, and in one manufacturer's polio vaccines only, which hopefully the shipments were tracked and records still exist of which hospitals/organizations/doctors/individuals received those. But even then, with the studies above showing that the link between SV40 and cancer is tenuous at best, chances are those people have increased their risks of getting cancer more from their lifestyle, environment, or genetics than from a viral infection alone.Some polio vaccines prepared from 1954 to 1961 were contaminated with infectious SV40. It has been assumed that all polio vaccines were SV40 free in the United States after 1961 and in other countries after 1962. Following a WHO requirement that was prompted by the detection of SV40 in some human tumors, we conducted a multilaboratory study to test for SV40 polio vaccines prepared after 1961. Vaccine samples from 13 countries and the WHO seed were initially tested by PCR. The possible presence of intact and/or infectious SV40 DNA in PCR-positive samples was tested by transfection and infection of permissive CV-1 cells. All results were verified by immunohistochemistry, cloning, and sequencing. All the vaccines were SV40 free, except for vaccines from a major eastern European manufacturer that contained infectious SV40. We determined that the procedure used by this manufacturer to inactivate SV40 in oral poliovirus vaccine seed stocks based on heat inactivation in the presence of MgCl2 did not completely inactivate SV40. These SV40-contaminated vaccines were produced from early 1960s to about 1978 and were used throughout the world.

How can you claim that? Show us one article that says he wants to inject anthrax into children. Or is truth totally unimportant?Arlen wrote: The restraints on Obama do not add to him. He is being restrained from action by more prudent forces. Nope, the title of the thread is appropriate.
