Guest guest Posted September 14, 1998 Report Share Posted September 14, 1998 There is more to the " A-B-C of hepatitis " than what public health officials and the media are telling parents when scare tactics are used to motivate them into having their babies receive the hepatitis B shot (the Province, Sept. 10/98). Epidemiological studies carried out in New Zealand by J. Barthelow Classen, MD, of Classen Immunotherapies Inc., Baltimore, land, at the request of New Zealand authorities (New Zealand Medical Journal, May 24, 1996) found a 65 percent increase in the incidence of insulin dependent diabetes among juveniles who had received the hep B vaccination. Dr. Classen, formerly with the United States National Institutes of Health, is a strong supporter for the use of vaccines in preventing disease. His findings have since been published in a peer reviewed journal and confirmed by studies carried out elsewhere. It seems that certain proteins in the vaccine may initiate an auto-immune response in susceptible children that attacks and destroys the insulin producing cells in their pancreas. There is other evidence surfacing that other auto-immune diseases (such as lupus) may be triggered by the vaccine. According to Health Canada there have been no reported children deaths from hepatitis B under the age of 15 in the last ten years. In 1996 there were 61 cases reported in this age group. These victims were either born to mothers who were infected or members of Asian communities where the disease is highly endemic. In light of the evidence, it is highly irresponsible for health authorities to suggest hepatitis B is such a wide spread health threat that justifies vaccinating thousands of babies not at risk for hepatitis B when the alarm has been sounded by a respected researcher that this vaccine has the potential to place many of those infants at risk of becoming insulin dependent diabetics. The failure to warn parents that these vaccines put their babies at serious risk calls in to question the competence of these health bureaucrats. The United States Congress instituted a taxpayer funded vaccine damage compensation program in 1986 when the vaccine manufacturers threatened to stop production because they could no longer afford liability costs and costly court awards. To date over $944,000,000 from this fund has been paid out. If these vaccines are so safe, why is it that manufacturers of the vaccines cannot get liability insurance for their product? Croft Woodruff, 6262 A Fraser Street Vancouver BC V5W 3A1 324 2121 >From Pediatric NewsRise in Type 1 Diabetes Blamed on Late Vaccination By: Miriam E. Tucker, Senior Writer [Pediatric News 32(4):4, 1998. ? 1998 International Medical News Group.] The incidence of type 1 diabetes is rising dramatically in American and European children. There are many theories about why this is happening, but one in particular is receiving a lot of media attention lately--that the increase may be linked with the timing of childhood immunizations. Experts agree that current data don't support that theory, although the possibility is being studied. In Allegheny County, Pa., which has the oldest type 1 diabetes registry in the United States, the incidence of the disease was at a stable 12 cases per 100,000 population aged 0-19 years from 1965 until the mid-1980s. Around 1985 the rate increased to about 18-19 per 100,000. Since 1994 it appears to have risen even more, according to LaPorte, Ph.D., who oversees the registry. Especially worrisome is the " extraordinary " increase among African Americans, who in the past have had lower rates of type 1 diabetes than whites. During the 1970s and 1980s, about 7-8 per 100,000 blacks aged 0-19 years developed type 1 diabetes. In the mid-1980s, that incidence rose to 11 per 100,000. Now for the first time, the incidence among African Americans--males in particular--is slightly higher than for whites. But type 1 diabetes is rising among whites, too, Dr. LaPorte, professor of epidemiology at the University of Pittsburgh, told this newspaper. Other U.S. registries have been in existence for less than 15 years, but the same trend seems to be occurring nationwide. Long-term European data show the same thing: In Finland, for example, which has the world's highest rate of type 1 diabetes, the incidence rose from 12 per 100,000 children aged 0-15 in 1953 to 38 in 1986, and to 45 in 1996. Throughout Europe the incidence of type 1 diabetes is rising about 2%-3% per year, while the United States is " probably a little higher, " Dr. LaPorte noted. One " hot " theory among researchers to explain the increase is that the autoimmune destruction of pancreatic islet cells may be triggered by a " superantigen, " possibly arising from a viral infection, a food, or a toxin. Some data support a link between type 1 diabetes and cow's milk. " We know it has to be something in the environment, since the gene pool can't change that rapidly, " Dr. LaPorte said. The media, however, has latched onto the theory of immunologist J. Barthelow Classen. He believes the immunization schedule, which begins immunizations at 2 months of age, is exacerbating the risk for type 1 diabetes and other autoimmune diseases. Giving these immunizations at birth could reduce the risk, he told this newspaper. He is president of Classen Immunotherapies Inc., a Baltimore company that is developing " immunization methods " and " methods of testing immunization schedules " to minimize the risk for development of type 1 diabetes. According to Dr. Classen, maternal viruses are passed on to the infant at birth and take hold within the first 6 weeks of life. Giving vaccines during this period would trigger the release of interferon, which would block the viral infections. When vaccines are given at 2 months of age, they exacerbate the virus-induced inflammation that is already occurring in the pancreatic islet cells. This is particularly true of the vaccines that contain killed components such as Haemophilus influenzae b (Hib), which activate macrophages, he said. In type 1 diabetes-prone mice, Dr. Classen found that giving low doses of killed human vaccines at birth completely prevented the development of diabetes, while immunizing at 8 weeks either increased the risk or did not change it. He also cites human epidemiologic data to support his theory: In various parts of the US and Europe, the institution of new vaccines has been followed by a rise in type 1 diabetes incidence. For instance, the diabetes increases in both Pittsburgh and Finland followed the introduction of the Hib conjugate vaccine, according to Dr. Classen. (The Hib vaccine was licensed in the United States in 1987). Immunization expert Dr. Katz said Dr. Classen's theory " is not yet supported by data. " What worries me is that this will create anxiety about immunizations. At this moment there is no basis for revising the immunization schedule, " said Dr. Katz, who has served on two Institute of Medicine vaccine safety committees and is the Carpentier Professor of Pediatrics Emeritus at Columbia University in New York. Dr. LaPorte went a step further: " I think [Dr. Classen] is completely wrong. " The increase in immunizations in the early 1960s did not affect diabetes incidence, and countries with good immunization coverage, like Japan and China, have not seen a rise in diabetes. Everyone--even Dr. Classen--says more data are needed before anyone considers manipulating the immunization schedule. The National Institute of Allergy and Infectious Diseases began a study in collaboration with British public health officials to gather all the data relating to the topic. They will hold a meeting to look at the findings later this year. At least three other conferences looking at the relationship between infectious diseases and autoimmunity are planned. The Centers for Disease Control and Prevention is also studying the relationship in an already-established database population of more than 500,000 children in four California HMOs. The agency will look at type 1 diabetes rates in children who received hepatitis B vaccine at birth and those whose first dose was given at 2 months, and it also will look at diabetes rates after use of the Hib vaccine began. Vaccine 1998 Feb;16(4):329-334 Major adverse reactions to yeast-derived hepatitis B vaccines--a review. Grotto I, Mandel Y, Ephros M, Ashkenazi I, Shemer J Israel Defense Force, Medical Corps, Israel. Yeast-derived recombinant DNA hepatitis B vaccines usage became widely accepted since the early 1990s. Severe adverse events have been reported infrequently in adults and rarely in infants and children given hepatitis B vaccine in the ten years which have passed since the introduction of the vaccine. Some of the data were summarized in previous review articles. Our review of the literature revealed reports of serious adverse reactions which included immediate reactions (anaphylaxis and urticaria) as well as delayed reactions, including skin, rheumatic, vasculitic (including Systemic Lupus Erythematosus and glumerulonephritis), hematologic, ophthalmologic and neurologic reactions. These cases were summarized and a pathogenetic mechanism is offered. PMID: 9607051, UI: 98269934 Quote Link to comment Share on other sites More sharing options...
