Als het dan toch zo onschadelijk zou zijn waarom is men dan gestopt met thiomersal ?
Dit is een artikel uit 2005. Inmiddels weten we dat het met die bijwerkingen wel meevalt:quote:A number of affluent countries are moving to eliminate thiomersal (thimerosal), an ethylmercury preservative, from vaccines as a precautionary measure because of concerns about the potential adverse effects of mercury in infants. The WHO advocates continued use of thiomersal-containing vaccines in developing countries because of their effectiveness, safety, low cost, wide availability and logistical suitability in this setting.
The guidelines for long-term mercury exposure should not be used for evaluating risk from intermittent single day exposures, such as immunisation using thiomersal-containing vaccines. Similar or higher mercury exposures likely occur from breast feeding and the health benefit of eliminating thiomersal from a vaccine, if any, is likely to be very small. On the other hand, the benefits accrued from the use of thiomersal-containing vaccines are considerably greater but vary substantially between affluent and developing regions of the world. Because of the contribution to overall mercury exposure from breast milk and diet in later life, the removal of thiomersal from vaccines would produce no more than a 50% reduction of mercury exposure in infancy and <1% reduction over a lifetime.
Different public policy decisions are appropriate in different settings to achieve the lowest net risk, viewed from the perspectives of the individual vaccinee or on a population basis. In developing regions of the world, at least over the next decade, far more benefit will accrue from protecting children against widely prevalent vaccine-preventable diseases by focusing efforts aimed at improving infant immunisation uptake by using current, inexpensive, domestically-manufactured, thiomersal-containing vaccines, than by investing in thiomersalfree alternatives.
Dat is dus meer dan voldoende bewijs ondertussen.quote:Thimerosal
Vaccine manufacturers who produce multidose vaccine
vials use thimerosal as a preservative. Thimerosal is approximately
50% mercury by weight, and it has been one of the
most widely used preservatives in vaccines. It is metabolized
or degraded to ethylmercury and thiosalicylate. Ethylmercury
is an organomercurial that should be distinguished
from methylmercury, a related substance that has been the
focus of considerable study (Thimerosal in Vaccines, n.d.).
Methylmercury is bioavailable and can accumulate in the
brain and cause neurologic damage. The ethylmercury found
in thimerosal is not bioavailable. In studies, ethylmercury
does not accumulate in the body or the brain and is metabolized
and cleared by the body. (Burbacher, Shen, Liberato,
Grant, & Cernichiari, 2005).
Thimerosal has antimicrobial qualities that keep vaccines
safe from inadvertent contamination through routine
multiple punctures in a vial. Thimerosal had been used by
vaccine manufacturers for years but came under scrutiny in
1999, as discussed earlier in this article. At that time, the
FDA and the CDC published statements that indicated
manufacturers should reduce or eliminate the amount of
thimerosal used in vaccines. The CDC further recommended
the birth dose of hepatitis B vaccine be suspended
for infants until thimerosal-free vaccine was available (CDC,
1999b).
The CDC stated:
. . . given the widely acknowledged value of reducing
exposure to mercury, vaccine manufacturers, the FDA,
and other Public Health Service (PHS) agencies are collaborating
to reduce the thimerosal content of vaccines or
to replace them with formulations that do not contain
thimerosal as a preservative as soon as possible without
causing unnecessary disruptions in the vaccination
system. The FDA will expedite review of supplements to
manufacturers’ product license applications that present
formulations for eliminating or reducing the mercury
content of vaccines. (CDC, 1999, p. 997)
Vaccine manufacturers then worked to assure removal of
thimerosal from vaccines. By 2001, all vaccines routinely recommended
for children 6 years of age and under in the
United States were produced without thimerosal as a preservative,
with the exception of some doses of inactivated influenza
vaccine. Today, all vaccines are available without
thimerosal, including several influenza vaccine presentations
(e.g., single-dose prefilled syringes and the intranasal
vaccine).
Many studies have been undertaken to examine the risks
associated with thimerosal in vaccines. In 2003, Stehr-Green
et al. assessed autism incidence and the use of thimerosalcontaining
vaccines: “Data did not support an association
between thimerosal-containing vaccines and autism in
Denmark and Sweden where exposure to thimerosal was
eliminated in 1992 and where autism rates continued to
increase” (Stehr-Green et al., 2003, p. 106).
Another study in 2003 utilized the Vaccine Safety Datalink
(VSD) to screen for possible associations between exposure
to thimerosal-containing vaccines and a variety of renal, neurologic,
and developmental problems: “No consistent significant
associations were found between thimerosal-containing
vaccines and neurodevelopmental outcomes” (Verstraeten
et al., 2003, p. 1,042).
The CDC conducted a follow-up study to the Verstraeten
et al. VSD study. This was a large study that also utilized the
VSD data to investigate a possible link between thimerosal in
vaccines and childhood developmental concerns. An excerpt
from the study finding reads:
. . . some people believe increased exposure to thimerosal
(from the addition of important new vaccines recommended
for children) explains the higher prevalence in
recent years. However, evidence from several studies
examining trends in vaccine use and changes in autism
frequency does not support such an association. Furthermore,
a scientific review by the Institute of Medicine
(IOM) concluded that “the evidence favors rejection of a
causal relationship between thimerosal-containing vaccines
and autism.” (CDC, 2007, p. 144.)
Thompson et al. (2007) further examined the hypotheses
that “increasing exposure to thimerosal is associated with
neurodevelopmental disorders. Findings did not support a
causal association between early exposure to mercury from
thimerosal-containing vaccines and immune globulins and
deficits in neuropsychological functioning at the age of 7 to
10 years” (Thompson et al., p. 1,290).

One reason people may be concerned about BPA is because human exposure to BPA is widespread. The 2003-2004 National Health and Nutrition Examination Survey (NHANES III) conducted by the Centers for Disease Control and Prevention (CDC) found detectable levels of BPA in 93% of 2517 urine samples from people six years and older. The CDC NHANES data are considered representative of exposures in the United States. Another reason for concern, especially for parents, may be because some animal studies report effects in fetuses and newborns exposed to BPA.

Since the end of the 1991 Gulf War, there have been reports of unexplained, multisymptom illnesses afflicting veterans who consistently report more symptoms than do nondeployed veterans. One of the many possible exposures suspected of causing chronic multisymptom illnesses Gulf War veterans is squalene, thought to be present in anthrax vaccine. We examined the relationship between squalene antibodies and chronic symptoms reported by Navy construction workers (Seabees), n=579. 30.2% were deployers, 7.4% were defined as ill, and 43.5% were positive for squalene antibodies. We found no association between squalene antibody status and chronic multisymptom illness (p=0.465). The etiology of Gulf War syndrome remains unknown, but should not include squalene antibody status.

om maar even één studie hiervan ertussen uit te lichten.

Thimerosal, a preservative used widely in vaccine formulations, contains ethylmercury. Thus it has been suggested that childhood vaccination with thimerosal-containing vaccine could be causally related to neurodevelopmental disorders such as autism. OBJECTIVE: To determine whether vaccination with a thimerosal-containing vaccine is associated with development of autism. DESIGN, SETTING, AND PARTICIPANTS: Population-based cohort study of all children born in Denmark from January 1, 1990, until December 31, 1996 (N = 467 450) comparing children vaccinated with a thimerosal-containing vaccine with children vaccinated with a thimerosal-free formulation of the same vaccine. MAIN OUTCOME MEASURES: Rate ratio (RR) for autism and other autistic-spectrum disorders, including trend with dose of ethylmercury. RESULTS: During 2 986 654 person-years, we identified 440 autism cases and 787 cases of other autistic-spectrum disorders. The risk of autism and other autistic-spectrum disorders did not differ significantly between children vaccinated with thimerosal-containing vaccine and children vaccinated with thimerosal-free vaccine (RR, 0.85 [95% confidence interval [CI], 0.60-1.20] for autism; RR, 1.12 [95% CI, 0.88-1.43] for other autistic-spectrum disorders). Furthermore, we found no evidence of a dose-response association (increase in RR per 25 microg of ethylmercury, 0.98 [95% CI, 0.90-1.06] for autism and 1.03 [95% CI, 0.98-1.09] for other autistic-spectrum disorders). CONCLUSION: The results do not support a causal relationship between childhood vaccination with thimerosal-containing vaccines and development of autistic-spectrum disorders

This study examined whether acquisition of neonatal reflexes and sensorimotor skills in newborn rhesus macaques (Macaca mulatta) is influenced by receipt of the single neonatal dose of Hepatitis B (HB) vaccine containing the preservative thimerosal (Th). HB vaccine containing a standardized weight-adjusted Th dose was administered to male macaques within 24h of birth (n=13). Unexposed animals received saline placebo (n=4) or no injection (n=3). Infants were raised identically and tested daily for acquisition of 9 survival, motor, and sensorimotor reflexes by a blinded observer. In exposed animals there was a significant delay in the acquisition of three survival reflexes: root, snout and suck, compared with unexposed animals. No neonatal responses were significantly delayed in unexposed animals compared with exposed. Gestational age (GA) and birth weight were not significantly correlated. Cox regression models were used to evaluate the main effects and interactions of exposure with birth weight and GA as independent predictors and time-invariant covariates. Significant main effects remained for exposure on root and suck when controlling for GA and birth weight such that exposed animals were relatively delayed in time-to-criterion. There was a significant effect of GA on visual follow far when controlling for exposure such that increasing GA was associated with shorter time-to-criterion. Interaction models indicated that while there were no main effects of GA or birth weight on root, suck or snout reflexes there were various interactions between exposure, GA, and birth weight such that inclusion of the relevant interaction terms significantly improved model fit. This, in turn, indicated important influences of birth weight and/or GA on the effect of exposure which, in general, operated in a way that lower birth weight and/or lower GA exacerbated the detrimental effect of vaccine exposure. This primate model provides a possible means of assessing adverse neurodevelopmental outcomes from neonatal Th-containing HB vaccine exposure, particularly in infants of lower GA or low birth weight. The mechanism of these effects and the requirements for Th is not known and requires further study.
