Guest guest Posted November 14, 2006 Report Share Posted November 14, 2006 FLU VACCINES FOUND TO BE INEFFECTIVE FOR CHILDREN Each year when flu season rolls around, we're reminded of the importance of getting annual flu shots, especially for high-risk groups like children. We take it for granted that it's the right thing to do . but is it? A study in the Journal of the American Medical Association (Oct. 25, 2006) says yes, while the recent conclusion of the Cochrane Collaboration - an international, not-for-profit, independent body that critiques health care outcomes - concluded that there is little scientific evidence backing the safety or effectiveness of the inactivated influenza vaccine in children (British Medical Journal, October 28, 2006). Calls for a Re-Evaluation of Annual Flu Shots The Cochrane Collaboration called for a re-evaluation of the strategy of routinely promoting annual flu vaccinations in children as public health policy, noting that " large-scale studies assessing important outcomes and directly comparing vaccine types are urgently required. " The National Vaccine Information Center - a national, non-profit, educational organization dedicated to the prevention of childhood vaccine injuries and deaths -- went even further. Given the Cochrane findings, along with what it considered to be methodological flaws in the JAMA study, the NVIC called for a halt on the Centers for Disease Control and Prevention (CDC) recommendation of annual influenza vaccinations for infants and children -- at least until we have the scientific evidence to back them up. To gain more perspective on the issues surrounding the influenza vaccine, I spoke with NVIC president Barbara Loe Fisher. She told me that there is a huge gap between the scientific research on the influenza vaccine and government policies on it. Fisher cites concerns such as methodological flaws in studies, safety considerations (i.e., adverse events due to vaccination) and the relative lack of effectiveness of the vaccines. About the Studies The JAMA study, which was conducted at Kaiser Permanente in California and funded by the CDC, looked at the medical records of children 6 to 23 months old who received the trivalent inactivated influenza vaccine (a vaccine containing dead flu viruses) as well as other vaccines between 1991 and 2003 (45,356 children with 69,359 vaccinations). As such, it was a non-randomized, retrospective analysis, rather than a more rigorous randomized, placebo-controlled trial. There were no unvaccinated controls. After examining children's medical records, researchers concluded that the influenza vaccine in children 6 to 23 months is associated with few medical problems, " none of which were serious " or " significantly associated with the vaccine. " Fisher was concerned, however, that adverse events due to the vaccine slipped through the cracks. She notes that cases of convulsions and Guillain-Barre Syndrome (a rare neurological disease characterized by loss of reflexes and temporary paralysis) were written off as coincidental or attributed to other vaccines. Fisher adds that nine of the nineteen Kaiser Permanente and CDC study authors reported financial ties to influenza vaccine manufacturers, and all received CDC funding. Although this does not necessarily mean that they were biased, it is a potential conflict of interest that raises red flags. The Cochrane Collaboration's analysis of flu vaccine studies reached a very different conclusion, pointing out the significant gap between public health policy and scientific evidence. Surprise was registered that there was only one study of inactivated flu vaccine in children under two years, given the recent US recommendation for vaccination of all healthy children from six months to two years old. Moreover, in children under two, the Cochrane Collaboration found that the effectiveness of inactivated vaccine was similar to placebo. It was impossible to carry out safety comparisons, because of the lack of rigorous, standardized, randomized, placebo-controlled studies. According to the Cochrane Collaboration, the influenza vaccine did not fare much better with adults. In an analysis of flu shots in healthy people under 65, there was no evidence that the vaccines had an impact on measurable factors such as time off work, hospital stays or mortality (death resulting from the flu or its complications). In the elderly, the results were so scattered that they were termed " both counterintuitive and implausible. " Further Research Is Necessary Clearly more research is necessary to come up with good, solid answers about the safety and effectiveness of influenza vaccines. Mark Stengler, ND, editor of Bottom Line's Natural Healing newsletter, likewise expresses concern that the flu vaccine, especially in regard to children, has no long-term studies to back it up. He worries that side effects such as neurological damage have not been properly assessed. In Dr. Stengler's view, it seems only prudent to conduct more thorough research on the flu vaccine for children, whose maturing organ systems are more prone to damage. Whatever decision you come to regarding flu shots, keep in mind that there are also many natural ways to avoid infection (wash hands, avoid exposure to infected people, etc.) and enhance immunity during flu season.
