Guest guest Posted October 2, 2005 Report Share Posted October 2, 2005 [PROVE NOTE: This article on the flu vaccine cites references to dozens of studies showing " no evidence vaccination reduces flu-related deaths or complications " in children under 2 and more studies showing " there was absolutely no decline in influenza-attributable mortality between 1980, when 15 percent of elderly were vaccinated, and 2000, when 65 percent of elderly were vaccinated. " It is absolutely incomprehensible that the CDC still goes on to maintain " that vaccination is the best way to protect children younger than 2 and people age 65 years and older from flu and its complications. " Think about this the next time you are asked to follow some other CDC vaccine policy. What is highlighted by this article and is just as ludicrous is that other researchers are proposing that since vaccinating the very young the old for the flu is useless, they suggest that we vaccinate everyone else who is healthy and doesn't need it to begin with. Of course they forgot to mention the lives of healthy people that are ruined by flu vaccine reactions. FluMist vaccine is being pushed for healthy kids and adults - it is a live viral vaccine squirted up your nose and it definitely has its own set of risks concerns. [see Risks of FluMist Vaccine at http://www.redflagsweekly.com/extra/2003_oct03_2.html] They want to come after everybody else now. The best protection against bad policy is knowledge and Dr. Yazbak has just written another great article for Red Flags called ”Influenza Vaccination of Infants: A Useless Risk. " This is a good one to forward to pregnant friends and new parents. It is appended below this article and posted at http://www.redflagsdaily.com/yazbak/2005_sep30.html.] --------------------------------------------- Oct. 1, 2005, 11:49AM Flu shots perhaps being aimed at wrong targets Studies suggest vaccinating the young, not the old, is more effective http://www.chron.com/cs/CDA/ssistory.mpl/health/3377513 By LEIGH HOPPER Copyright 2005 Houston Chronicle Are the wrong people first in line for flu shots? New research shows flu vaccines may not be as effective as previously thought for the elderly and very young. In fact, the best way to protect the elderly from flu-related deaths may be to vaccinate schoolchildren — the biggest spreaders of flu. But federal health officials are limiting shots this month to seniors and other " high-priority " groups — an approach some influenza experts say is scientifically flawed and perhaps a waste of vaccine. " (Rationing) didn't work last year and I don't think it will work this year either, " said Baylor College of Medicine flu expert Glezen, who says he thinks vaccinating children and adults as fast as possible is the best way to protect the community from an outbreak. " It's simply a matter of missed opportunities. One of the basic tenets of immunization practice is never miss an opportunity. " No flu vaccine shortage is expected this year, and beginning Oct. 24, flu shots will be available to all. Until then, the U.S. Centers for Disease Control and Prevention, which sets vaccine policy, is recommending shots for people 65 and older and others thought to be at high risk for severe flu complications. Today marks the beginning of flu season, which typically peaks in January or February in Houston. Flu shot clinics in pharmacies and in nursing homes start Monday. The flu shot offers no protection against avian influenza, a mounting concern in Asia that is fueling consumer interest in protection against the ordinary flu. Rationing precaution The rationing is a precaution against the temporary shortage that occurred last year when flu vaccine maker Chiron Corp.'s manufacturing plant was shut down, cutting the U.S. supply in half. In that case, shots were administered to the elderly and those with chronic illnesses first, creating long lines. Once the flu vaccine again became available to the general public, many people, thinking the threat had passed, lost interest and the shots sat on shelves. " I am a little concerned people will not remember to come back and get a vaccine later on when this is available, " said Dr. Arnold Monto, a University of Michigan flu expert who argues that vaccinating children as well as the elderly for the flu has a significant impact on controlling epidemics. Scientists know that the elderly are at greatest risk of dying from the flu, but they also have the weakest responses to a vaccine because of their aging immune systems — raising questions about whether they are the best target for flu shot campaigns. The CDC's long-accepted recommendations are being challenged by fresh analysis of flu death data and previously published research. For example: * The British medical journal The Lancet in September published an analysis of 64 studies evaluating the effectiveness of flu vaccine for the elderly. The analysis found flu shots were only modestly effective, cutting flu-related hospitalizations by 30 percent to 42 percent. * In February, The Lancet published a similar analysis of 25 studies of flu shots in children younger than 2, the other group targeted by CDC campaigns. There is no evidence vaccination reduces flu-related deaths or complications in that group, researchers concluded. * A study published in February in the Archives of Internal Medicine examined decades of U.S. data and found no decrease in flu deaths among seniors despite increased vaccine coverage. " There was absolutely no decline in influenza-attributable mortality between 1980, when 15 percent of elderly were vaccinated, and 2000, when 65 percent of elderly were vaccinated, " said Boston flu researcher Dr. Tom Reichert, a co-author of the National Institutes of Health study. The CDC maintains that vaccination is the best way to protect children younger than 2 and people age 65 years and older from flu and its complications. Some flu experts think there is a better way: Immunize schoolchildren, well-known to parents and doctors as petri dishes of germs. Study supports theory A study co-authored by Glezen supports this strategy. In that study, close to 15,000 children within the and White Health Plan HMO in Temple and Belton were recruited for free vaccinations during three years. That community was compared with another and White site (Waco, and College Station) where schoolchildren weren't actively recruited. What researchers found: Vaccination of only 20 percent to 25 percent of eligible children significantly reduced respiratory illness in people older than 35. A study of Japanese health data makes the same point. Between 1972 and 1987, Japan's schoolchildren were required by law to receive flu vaccinations, said Reichert. Almost no elderly were vaccinated during that time — but deaths among seniors dropped dramatically. When the campaign stopped, flu deaths among the elderly rose again. " The truth is, nobody's going to stop vaccinating these high-risk groups, " said Reichert. " In my view, it's not necessary to divert vaccine but to enhance our vaccination program ... by vaccinating schoolchildren. Really, it would cost about $150 million. There's no good reason why we shouldn't do it. " Incidentally, there is an ouch-free flu vaccine available now for children older than 5 who are healthy, as well as healthy adults younger than 50. FluMist, developed in part by Baylor and made by MedImmune, is a nasal-spray vaccine which is not part of the CDC's rationing plan. Healthy people 5 to 49 years old who are not pregnant, including health-care workers who are not caring for severely immuno-compromised patients in special-care units, can receive FluMist at any time, according to CDC. At $25 a dose, FluMist — which is made with a weakened live virus and therefore more powerful than shots — is about twice as expensive as an injection and is generally available only through private physicians. ------------------------------------------------------- Influenza Vaccination of Infants: A Useless Risk By Red Flags Columnist, F. Yazbak, MD, FAAP (tlautstudy@...) Dr. Yazbak, a pediatrician, now devotes his time to the research of autoimmune regressive autism and vaccine injury. http://www.redflagsdaily.com/yazbak/2005_sep30.html In the spring of 2004, the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) recommended that all children 6- to 23-months of age be vaccinated against influenza because they were at “substantially increased risk for influenza-related hospitalizations.” (1) A review in The Lancet suggests that influenza vaccination of infants is useless. The influenza vaccines There are two types of influenza vaccines on the U.S. market. One is the recently released intranasal live virus vaccine that is not recommended for infants and children under five. MedImmune’s FluMist® will not, therefore, be discussed in this article. The second is the older and well-known inactivated (killed) influenza vaccine that is administered by injection in the following dosage: Children 6- to 36-months: 0.25 ml/dose Children older than 3 years: 0.5 ml/dose Adults: 0.5 ml/dose Infants and young children receiving the vaccine for the first time should receive two doses one month apart. They, in fact, receive an adult dose within one 30-day period. Only split-virus, subvirion, or purified surface antigen vaccines should be administered to children because of their decreased potential for causing febrile reactions. (1) This year, Sanofi Pasteur will produce between 50 and 60 million doses of influenza vaccine for the U.S. market. GlaxoKline (GSK) is planning to produce and sell about 8 million doses in the U.S., since the FDA licensed its product on Aug. 31, 2005. (2) Chiron’s Liverpool facility has been trying to correct its manufacturing problems for more than a year and will need approval by the British MHRA (Medicines and Healthcare products Regulatory Agency) and the U.S. Food and Drug Administration (FDA) before it can ship out its first dose of vaccine. It is clear that Chiron is already too late for the start of the season. In the best scenario, it will provide 18 million to 26 million doses of vaccine for use in the United States. It is evident that there will be a shortage of injectable influenza vaccine this season and that the CDC will have to promote the use of the intranasal live vaccine for those individuals for whom it is indicated. Presentation and Preservatives Sanofi Pasteur (Aventis Pasteur) offers four different options in its influenza vaccine Fluzone®: three thimerosal-free single-dose presentations including a 0.25 ml syringe for children 6 months to 35 months of age; either a 0.5 ml syringe or a 0.5 ml vial for persons aged 3 years and older; and a multi-dose vial with thimerosal as a preservative, licensed for those ages 6 months and above. (www.fda.gov/cber/products/inflave071405.htm) The GSK U.S. product will be available in 0.5 ml syringes containing a trace amount of thimerosal remaining from the production process. The vaccine is licensed for adult use. http://www.fda.gov/cber/products/inflgla083105.htm Chiron, if approved by the FDA and MHRA, will provide most of their U.S. product in multi-dose vials with thimerosal as a preservative — presumably for adults. They may also provide for children over the age of 4 years and for adults some 0.5 ml syringes containing trace amounts of thimerosal. (2) The following table summarizes the relevant FDA information on the thimerosal content of all licensed influenza vaccines as of Sept. 6, 2005. (3) Trade Name Manufacturer Thimerosal Mercury Concentration Fluzone Aventis Pasteur Inc. 0.01% 25 µg/0.5 ml dose Fluvirin 0.01% 25 µg/0.5 ml dose Fluzone Aventis Pasteur Inc. 0 0 (no Thimerosal) Fluvirin < 0.0004% < 1 µg/0.5 ml dose (preservative free) Fluarix Glaxo-Kline < 0.0005% < 1.25 µg/0.5 ml dose To date, there is no national recommendation to use thimerosal-free or preservative-free flu vaccines exclusively in infants and younger children. The CDC recommendation seems to be that thimerosal-free brands are preferred if they are available. If not, any available inactivated flu vaccine can be used in order to “protect” the infants. Few states have mercury-free pediatric vaccine laws. Influenza vaccination of infants Is influenza vaccination of 6- to 24-month-old infants effective? Will it decrease influenza-related hospitalizations as claimed by the ACIP? The answer to both questions appears to be no. This answer is based on an extensive review published in the Feb. 25, 2005 issue of The Lancet. The authors, Jefferson, , Demicheli et al, literally analyzed every available reference on the subject that they could find in the Cochrane Library, MEDLINE, EMBASE Biological Abstracts and Science Citation Index to June 2004 — in any language. They included 14 randomized controlled trials, eight cohort studies, one case-control study and one randomized controlled trial of intraepidemic use of the vaccine. (4) The authors also: Contacted the vaccine manufacturers and the authors of all relevant studies And included every study ever published that compared the efficacy of influenza vaccines. Surprisingly, they only found two small studies that assessed the effects of influenza vaccines on hospital admissions (the alleged reason for the CDC’s ACIP recommendation). And they could not find a single study that assessed reductions in mortality, serious complications or even community transmission of the disease. Following a review of all the information they could find worldwide, the authors came to the following conclusions concerning the use of inactivated influenza vaccines in children younger than two years of age: There is no evidence of the effectiveness of the vaccine or reduction in symptomatic cases. The efficacy of the vaccine, reduction in laboratory-confirmed cases, is similar to that of placebo. In its publication Efficacy and Effectiveness of Inactivated Influenza Vaccine, dated Aug. 8, 2005 and intended to support its recommendation, the CDC concedes in its opening statement that the effectiveness of inactivated influenza vaccine depends primarily on the age and immunocompetence of the vaccine recipient and the degree of similarity between the viruses in the vaccine and those in circulation. (5) The following is all the information concerning the effectiveness of the inactivated influenza vaccine in children 6- to 23-months old that is available in that publication on the CDC web site: “Children aged > 6 months can develop protective levels of anti-influenza antibody against specific influenza virus strains after influenza vaccination, although the antibody response among children at high risk for influenza-related complications might be lower than among healthy children…. “A 2-year randomized study of children aged 6--24 months determined that > 89% of children seroconverted to all three vaccine strains during both years. During year 1, among 411 children, vaccine efficacy was 66% (95% confidence interval [CI] = 34%--82%) against culture-confirmed influenza (attack rates: 5.5% and 15.9% among vaccine and placebo groups, respectively). During year 2, among 375 children, vaccine efficacy was --7% (95% CI = --247%--67%; attack rates: 3.6% and 3.3% among vaccine and placebo groups, respectively; the second year exhibited lower attack rates overall and was considered a mild season). However, no overall reduction in otitis media was reported…. “A retrospective study among approximately 5,000 children aged 6--23 months conducted during a year with a suboptimal vaccine match indicated vaccine effectiveness of 49% against medically attended, clinically diagnosed pneumonia or influenza (International Classification of Diseases, Ninth Revision [iCD-9] codes 480--487) among children who had received 2 doses of influenza vaccine. No effectiveness was demonstrated among children who had received only 1 dose of influenza vaccine, illustrating the importance of administering 2 doses of vaccine to previously unvaccinated children aged <9 years).” That’s it: 230 words. A careful review of the CDC information reveals the following: Antibody response among children at high risk for influenza-related complications appears to be lower than among healthy children. In other words, children who were more likely to be hospitalized had less antibody response and less benefit from the vaccination. First study: During year two, vaccine efficacy among 375 children, was --7% against culture-confirmed influenza (95% CI = --247%--67%; attack rates: 3.6% and 3.3% among vaccine and placebo groups, respectively) and there was no reduction in ear infections. During year 1, vaccine efficacy was better. The study did not examine complications or hospital admissions. Second study: One dose of influenza vaccine was totally ineffective. Children who received two injections of vaccine had a 49 percent reduction in “clinically diagnosed” pneumonia or “influenza.” Because these were not culture-confirmed cases, the clinical illnesses may not have been due to the influenza virus or may have been due to a different strain of virus than that in the vaccine. In either case, vaccination would not have influenced the course of the illness — one way or the other. Jefferson and associates concluded that immunization of very young children “is not lent support by the findings” of their extensive and detailed research of the world literature and could not find convincing evidence that vaccines can reduce mortality, admissions, serious complications, and community transmission of influenza. (4) The Lancet study was funded by Regione Piemonte, Italy, the Oxford Childhood Infection Study, University of Oxford and a program grant from the U.K. Medical Research Council (MRC). Given that the MRC and The Lancet are two historically pro-vaccine institutions, the results of this careful review must be taken very seriously. The two studies quoted by the CDC are limited, weak and irrelevant. The CDC and its Advisory Committee on Immunization Practices have a simple choice: They can continue recommending the useless influenza vaccination of infants aged 6 to 24 months Or They can do the right thing and rescind the 2004 recommendation. Now that is a tough choice!
