Guest guest Posted March 30, 2001 Report Share Posted March 30, 2001 Fabrications and Distortions To discover why people would want " philosophic exemptions " from one or more immunizations, I examined the Internet sites of the anti-immunization activists. Here I found what I expected. There is rhetoric about " making informed choices, " plus a mass of half-truths and (at most sites) outright, obvious lies. The links are mostly to other " alternative " medicine sites. In particular, these people make a practice of citing scientific papers and lying about their contents. Several cite references to 1990s-era publications in refereed medical journals. None of the authors use their sources truthfully. A Web site called " Dispelling Vaccine Myths " (www.unc.edu/~aphillip/www/vaccine/dvm1.htm) is typical. The author's most obviously untrue claims -- that immunizations have not made the diseases less common and that 29972 Japanese died of smallpox despite having been immunized -- are referenced only to the works of other anti-immunization activists. The author also cites the Lancet[26] to claim that " Oman experienced a widespread polio outbreak six months after achieving complete vaccination. " A check of the source shows this to be a cynical lie. Coverage was far from complete. Exposure was so massive where herd immunity was low that a few immunized children were not protected. The author cites MMWR's account[27] of an outbreak of measles spreading from unimmunized people to vaccine nonresponders in order to support the claim that the vaccine is ineffective. The statistics presented actually showed that the vaccine gave a high level of protection. He cites the New England Journal of Medicine (NEJM)[28] to claim that Romanian children have contracted polio from the vaccine. The article actually shows that polio was already common in the country, and that those children who already had polio when they were injected were more likely to develop paralysis -- a well-known phenomenon. The site contains a fabricated quotation from a Swedish epidemiologist, and the statement that " England, Wales, and West Germany had more pertussis fatalities in 1970, when the immunization rate was high, than during the last half of 1980, when rates had fallen. " This statement does not appear in the article to which it is referenced.[29] The author claims that " oth national and international studies have shown vaccination to be a cause of [sudden Infant Death Syndrome] SIDS. " He cites no international study. He cites one unrefereed paper by one presenter at a scientific meeting, a review of 70 cases; the claim of having a statistically significant clustering of SIDS deaths is made without presenting any statistics.[30 ] The author misrepresents an article in the American Journal of Epidemiology[31] as arguing that confounding could have masked vaccine as a cause of SIDS. The truth is that both participants in the discussion agreed that it could not. The author claims that the Japanese found that the whole-cell pertussis vaccine was statistically linked to SIDS. He gives no references (and can't, because it is not true), but the source of the misunderstanding is probably a JAMA article.[32] SIDS, by definition, affects children during the first year of life. When the Japanese stopped immunizing babies under age 1, there were no cases of SIDS following immunization. " Parents Advocating Vaccine Education " (www.unidial.com/~metroprint/pave2.html) misrepresents the Italian experience with pertussis. Citing a JAMA article[33] in which the vaccine was only 36% effective at the height of an epidemic (when people are inhaling huge numbers of bacteria), the author claims that this means the vaccine only works when the patient is not exposed. The author must actually know that pertussis bacteria are widespread throughout Italy, and there are always opportunities for exposure. The remaining claims are not referenced. The ridiculous claim that rubella immunization places future unborn children at increased risk for congenital rubella syndrome is referenced only to works by other anti-immunization activists. The author reports the views of an independent thinker on " stealth viruses " as fact, and claims these may be in vaccines. No mainstream virologist even writes about these hypothetical creatures. The author cites reports of retrovirus fragments in vaccines, but fails to add that despite much effort, nobody at the CDC could grow them, indicating no infectious particles were present. Finally, the author repeats the claim recently made by two indepoendent thinkers using their private methods,[34] that some diseases, such as childhood diabetes, are becoming more common, and perhaps immunization is the cause. If this were true, some honest scientist would have made a reputation by demonstrating a temporal relationship between immunization and the onset of diabetes. It hasn't happened. And if this were true, there would have been a tremendous upsurge in childhood diabetes when immunizations first became widespread. It didn't happen, and the mose recent work has shown no connection.[35] The author finishes by imputing the most vile motives to physicians, industry, and government. When " Think Twice " (thinktwice.com/studies.htm) tells its visitors that " Science reported on a possible link between polio vaccines and the origin of AIDS, " the author fails to mention that this was nothing more than a pair of letters about a Rolling Stone article whose author admitted it was idle speculation.[36] The author cites " studies " (actually, only one study in JAMA) as support for the claim that asthma is more common in recipients of the pertussis vaccine.[37] A subsequent large study refuted the claim utterly,[38] and scientific misconduct was described in a previous study claiming a link.[38] In the original JAMA article, 16 of the 203 unimmunized children had already had pertussis, compared with 1 of 243 in the immunized group. The author cites the Journal of Infectious Diseases,[39] alleging that DPT makes it more likely that a polio infection will turn paralytic. The article merely reported an illustration of the previously mentioned, well-known phenomenon resulting from injection during acute polio. The author cites an increasing prevalence of hepatitis B among intravenous drug abusers despite the existence of a vaccine.[40] However, the author neglected to say that the vaccine never reached these people. The author cites an old article in NEJM to claim that the original hepatitis B vaccine may have contained AIDS virus.[41] This was mere speculation at the time, and now we know it never happened. The author cites another NEJM[42] article to claim that hepatitis B vaccine causes acute polyneuropathy. Actually, this was the report of a single case following immunization. Subsequent studies have shown no statistical relationship. " Vaccinations -- Not Safe, Not Effective " (www.pnc.com.au/~cafmr/online/vaccine/vacc.html) cites a NEJM paper as support for the claim: " A report on a study of 11 healthy individuals to determine the effects of routine tetanus booster vaccinations showed that the vaccinations weaken the immune system of the recipients. " What actually happened is that the circulating counts of T4 cells dropped, though not to dangerous levels, as these cells migrated to the site of immunization. And the author of the Web page fails to mention that all blood work returned to normal in a month. The author quotes Pediatrics[43] as saying that the H. flu meningitis vaccine has been shown to cause serious reactions including convulsions, anaphylactoid allergic reactions, serum sickness-like reactions, and death. Actually, these were only reports of temporal associations, without further evidence of causality. The author claims that atypical measles, which is wild-strain measles in people who received only the killed vaccine, as " a very severe form of the disease in which it appears that, because of the vaccination, there is an increased susceptibility to measles virus, resulting from a damaged immune system. " The truth is that atypical measles is not " very severe, " but variable; only one patient in the cited JAMA[44] article was seriously sick, and both patients recovered. Actually, atypical measles results from a vaccine-enhanced antibody production to wild virus in those whose T-cells did not respond to the immunization. To characterize this as a " damaged immune system " is a shameless lie. The author cites MMWR's note[45] that mumps is now largely a disease of older people, and twists the language to claim (falsely) that it is now more common among these people than before immunization was available. " Unknowing Women Victims of Hidden Birthcontrol [sic] Vaccine " (home.sprynet.com/~noshots/hcg.htm) tells a frightful story of women in developing countries being giving a tetanus vaccine that caused them to miscarry. The vaccine was supposedly the work of Orwellian UN officials bent on controlling population. Thankfully, it's just another cynical lie, as a check of the actual Lancet[46] reference will show. The women did not know why they were being immunized, and were suspicious. But there were no miscarriages reported. An anticontraception conspiracy buff site (new-atlentean.com/birthcon.htm) is a " Think Twice " mirror. It claims that human chorionic gonadotropin (hCG) was introduced into tetanus toxoid to sterilize women. If this were true, it would be a terrible human rights violation. But the only evidence is an unpublished report that hCG was assayed in the vaccine. Using assays with extreme sensitivity but relative nonspecificity will generally give a small positive number even when none of the analyte is really present. These are not isolated examples, but are typical of how these Web sites use scientific citations. Obviously, the activists making these claims are yelling " Fire! " when there is none. What disturbs me the most is that there seems to be no internal self-criticism in the anti-immunization community. The most obvious lies go unchallenged.
