SUMMARY

Infectious agents contribute to the environmental factors involved in the development of autoimmune diseases possibly through molecular mimicry mechanisms. Hence, it is feasible that vaccinations may also contribute to the mosaic of autoimmunity. Evidence for the association of vaccinations and the development of these diseases is presented in this review.

Boys receiving the hepatitis B vaccine series were nine times more likely to need special education and be developmentally disabled.

TITLE

Hepatitis B triple series vaccine and developmental disability in US children aged 1-9 years

CITATION

Gallagher C, Goodman M. Toxicological and Environmental Chemistry. 2008;90(5):997-1008.

SUMMARY

This study investigated the association between vaccination with the hepatitis B triple series vaccine (pre-2000) and subsequent developmental disability. The odds of receiving special education were approximately nine times as great for vaccinated boys as for unvaccinated boys, after adjustment for confounders. The evidence, statistically significant, suggests that boys in United States who were vaccinated with the triple series hepatitis B vaccine were more susceptible to developmental disability than were unvaccinated boys.

Delay in diphtheria, pertussis, tetanus vaccination is associated with a reduced risk of childhood asthma?

CITATION

McDonald KL, Huq SI. Journal of the American Academy of Allergy, Asthma and Immunology. 2008;121:626-631.

SUMMARY

“Early childhood immunizations have been viewed as promoters of asthma development by stimulating a T(H)2-type immune response or decreasing microbial pressure, which shifts the balance between T(H)1 and T(H)2 immunity. Among 11, 531 children who received at least 4 doses of DPT, the risk of asthma was reduced to (1/2) in children whose first dose of DPT was delayed by more than 2 months.”

Neonatal deaths following hepatitis B vaccination should be investigated as possible vaccine-related deaths.

TITLE

An investigation of infant deaths following initial hepatitis B vaccination based on the Vaccine Adverse Event Reporting System (VAERS), 1992-2002

CITATION

Soldatenkova VA, Yazbak FE. Medical Veritas. 2007;4:1414-1421.

SUMMARY

This study argues that all unexpected neonatal deaths occurring after initial hepatitis B vaccination should be systematically investigated. Over one-fifth (22%) of neonatal hepatitis B vaccine injuries reported to the U.S. Vaccine Adverse Event Reporting System (VAERS) from 1992 to 2002 were deaths (38/170) that, in nearly all cases, occurred within hours or days of vaccination. Although most of the deaths were officially classified as sudden infant death syndrome (SIDS) or “unexplained” rather than as vaccine-related deaths, the authors note “a statistically significant increase in [the] proportion of neonatal SIDS since implementation of universal vaccination of newborns against hepatitis B.” The VAERS reports also are suggestive of higher risks for premature, small, or slightly ill infants.

Secular declines in cognitive test scores: A reversal of the Flynn Effect

CITATION

Teasdale TW, Owen DR. Intelligence. 2008;36:121–126.

SUMMARY

Scores on cognitive tests have been very widely reported to have increased through the decades of the last century, a generational phenomenon termed the “Flynn Effect” since it was comprehensively documented by James Flynn in the 1980s. Data reported here from young adult males in Denmark show that whereas there were modest increases between 1988 and 1998, scores on all four tests declined between 1998 and 2003/2004.

SUMMARY

In a study of children under 2 years of age in Guinea-Bissau, Kristensen et al. (2000) found immunization with Bacille Calmette Guerin (BCG) vaccine to be associated with lower mortality, but stated that oral polio vaccine (OPV) and diphtheria, tetanus, polio (DTP) vaccines were associated with higher mortality. More recently, it has been suggested that this effect may be gender-specific, existing primarily among girls. This evaluation, focused on relating timing of BCG and DTP vaccine receipt to mortality from 1 week to 6 months of age, with emphasis on gender differentials found that girls that received both BCG and DTP experienced higher mortality than those who received only one of the two vaccines.

TITLE

Mercury toxicity: Genetic susceptibility and synergistic effects

CITATION

Haley BE. Medical Veritas. 2005;2:535–542.

SUMMARY

This article discusses mercury intoxication and several normally appearing factors that increase the susceptibility to mercury toxicity. Boys with autism represent a subset of the population that is more susceptible to the toxic effects of mercury and thimerosal because they are not efficient excretors of these toxic materials. Research confirms that a lead-toxic person would be more susceptible to mercury toxicity than a healthy, non-toxic person. Researchers routinely observe that many heavy metals increase the apparent toxicity of low levels of mercury. In other words, the synergistic effects of other heavy metals, diet, antibiotics, etc. on mercury toxicity make it impossible to define a “safe level of mercury exposure.”

SUMMARY

Prior to the introduction of vaccines, children who were absent at a village examination had the same mortality as children who were present. During 1984-1987, children receiving DTP at 2-8 months of age had higher mortality over the next 6 months, the mortality rate ratio (MR) being 1.92 (95% CI: 1.04, 3.52) compared with DTP-unvaccinated children, adjusting for age, sex, season, period, BCG, and region. The MR was 1.81 (95% CI: 0.95, 3.45) for the first dose of DTP and 4.36 (95% CI: 1.28, 14.9) for the second and third dose. BCG was associated with slightly lower mortality (MR = 0.63, 95% CI: 0.30, 1.33), the MR for DTP and BCG being significantly inversed. Researchers found in low-income countries with high mortality, DTP as the last vaccine received may be associated with slightly increased mortality. Since the pattern was inversed for BCG, the effect is unlikely to be due to higher-risk children having received vaccination. The role of DTP in high mortality areas needs to be clarified.

A Sharma, JM Benzecry, V-A Power-Charnitsky and RC Deth. Molecular Psychiatry , (2004) 9, 358–370.

SUMMARY

“The ethylmercury-containing preservative thimerosal inhibited both IGF-1- and dopamine-stimulated methylation with an IC50 of 1nM and eliminated MS activity. Our findings outline a novel growth factor signaling pathway that regulates MS activity and thereby modulates methylation reactions, including DNA methylation. The potent inhibition of this pathway by ethanol, lead, mercury, aluminum and thimerosal suggest that it may be an important target of neurodevelopmental toxins.”

SUMMARY

Research on vaccines in developing countries recommended by the World Health Organization has emphasised serological responses and protection against specific diseases. The aim of the research has been to optimise vaccine schedules for control, elimination, or eradication of disease. In modelling exercises, vaccination against diphtheria, pertussis, tetanus, and polio has been assumed to save 1.5­2.0% of the children in areas with high infant mortality. However, these assumptions are not supported by data. Mortality was lower in the group vaccinated with any vaccine compared with those not vaccinated, however, recipients of one dose of diphtheria, tetanus, and pertussis or polio vaccines had higher mortality than children who had received none of these vaccines.

Effects of Diphtheria-Tetanus-Pertussis or Tetanus Vaccination on Allergies and Allergy-Related Respiratory Symptoms Among Children and Adolescents in the United States

CITATION

Eric L. Hurwitz, DC, PhD, and Hal Morgenstern, PhD. Journal of Manipulative and Physiological Therapeutics, Volume 23, Number 2, February 2000.

SUMMARY

“Asthma and other allergic hypersensitivity reactions and related symptoms may be caused, in part, by the delayed effects of DTP or tetanus vaccination. Because the proportion of US children who have received at least 1 dose of DTP vaccine approaches 100%, the number of allergies and allergy-related conditions attributable to DTP or tetanus vaccination in the United States may be very high. For example, assuming that the estimated vaccination effect is unbiased, 50% of diagnosed asthma cases (2.93 million) in US children and adolescents would be prevented if the DTP or tetanus vaccination was not administered.”

A high percentage of autistic children with positive antibodies to the measles and/or human herpesvirus-6 (HHV-6) also have autoantibodies to brain components. Might the MMR vaccine be an early event in brain autoimmunity?

TITLE

Serological association of measles virus and human herpesvirus-6 with brain autoantibodies in autism.

CITATION

Singh VK, Lin SX, Yang VC. Clin Immunol Immunopathol. 1998 Oct;89(1):105-8.

SUMMARY

Environmental exposures to toxins as well as viral infections are known to be triggers for autoimmunity. Individuals with autism suffer from a variety of immunological abnormalities with 55-70% having autoantibodies to brain antigens that include myelin basic protein (MBP), neuron-axon filament proteins (NAFP), and serotonin receptor. Many parents have reported the onset of autism soon after receiving a vaccine for the measles-mumps-rubella (MMR) and/or diptheria-pertussis-tetanus (DPT). The authors point out that both measles virus and human herpesvirus-6 (HHV-6) can manifest neurologic sequelae, show molecular mimicry with MBP and NAFP, and are associated with demyelination. To understand a possible association of viruses to brain autoimmunity, these researchers investigated virus serology of the measles virus and HHV-6. Children diagnosed with autism using the DSM-IIIR criteria were compared to normal controls. Both the controls and the children with autism had a high percentage of positive titers to measles as well as HHV-6 antibodies. According to the authors this was to be expected given that, “A high proportion (78%) of general populations is known to have positive titers of HHV-6 antibody.” The high percentage of measles antibody titers (85%) in children with autism was also expected. There is a high rate of seroconversion post MMR vaccination and none of the children had a history of exposure to the wild-type measles infection. An interesting finding was revealed when comparing the virus serology to brain autoantibodies. Among the control group, there were no brain autoantibodies found in any participant. However, among autistic subjects:

“approximately 90% of measles-IgG-positive sera also had anti-MBP”

“73% of measles-IgG- positive sera also had anti-NAFP”

“84% of HHV-6-IgG-positive sera also had anti-MBP”

“72% of HHV-6-IgG-positive sera also had anti-NAFP.”

“the higher the virus antibody titer the greater the chance of brain autoantibody”

The report closing by stating, “In conclusion, we suggest that while the etiology is not known, it is quite instructive to consider environmental factors, for example measles virus and HHV-6, as etiological agents linked to autoimmunity in autism.”

The timing of pediatric immunizations and the risk of Insulin-Dependent diabetes mellitus

CITATION

Classen David C.; Classen, John Barthelow; Infectious Diseases in Clinical Practice: September-October 1997 – Volume 6 – Issue 7 – ppg 449-454.

SUMMARY

Insulin-dependent diabetes mellitus (IDDM) is believed to be an autoimmune disease induced by a variety of environmental stimuli. Vaccines and infectious agents have been suggested to have an influence, but most of this research has been centered on the ability of these agents to infect the pancreatic islet cells or contain antigens that mimic autoantigens. Classen found that administration of the diphtheria-tetanus-pertussis (DTP) and anthrax vaccines to mice and rats at birth prevented the development of diabetes, whereas administration of the DTP vaccine starting at 8 weeks was associated with an increased incidence of diabetes.

Experimental Epilepsy in the Monkey Following Multiple Intracerebral Injections of Alumina Cream

CITATION

Joseph G. Chusid, Lenore M. Kopeloff, Ph.D. and Nicholas Kopeloff, Ph.D. The Bulletin, 1953.

SUMMARY

The multiple intracerebral injection of alumina cream (aluminum hydroxide cream) into a principal cerebral sensorimotor cortical area is effective in producing chronic epilepsy in monkeys. In all injected animals a variable degree of contralateral hemiparesis was obvious immediately after operation. In five of the six monkeys injected unilaterally, spontaneous contralateral focal motor seizures were evident three to four weeks after operation. Initially there occurred almost continuous twitch-like movements of varying amplitude and regularity, involving the musculature of the contralateral face and limbs. Excitement, agitation, movement or stress readily aggravated and accentuated this type of motor activity and sometimes led to Jacksonian spread with full-blown generalized convulsive seizure and exhaustion.
