“vaccine experts tend to look at the population as a whole, not at individual patients. And population studies are not granular enough to detect individual metabolic, genetic, or immunological variation that might make some children under certain circumstances susceptible to neurological complications after vaccination.
She also stated, amongst other points, that:
thimerosal crosses the placenta, and pregnant women are advised to get flu shots, which often contain it.
As of this posting the web site of the US Food and Drug Administration states: Over the past several years, because of an increasing awareness of the theoretical potential for neurotoxicity of even low levels of organomercurials and because of the increased number of thimerosal containing vaccines that had been added to the infant immunization schedule, concerns about the use of thimerosal in vaccines and other products have been raised. Indeed, because of these concerns, the Food and Drug Administration has worked with, and continues to work with, vaccine manufacturers to reduce or eliminate thimerosal from vaccines.
Thimerosal has been removed from or reduced to trace amounts in all vaccines routinely recommended for children 6 years of age and younger, with the exception of inactivated influenza vaccine (see Table 1). A preservative-free version of the inactivated influenza vaccine (contains trace amounts of thimerosal) is available in limited supply at this time for use in infants, children and pregnant women. Some vaccines such as Td, which is indicated for older children (≥ 7 years of age) and adults, are also now available in formulations that are free of thimerosal or contain only trace amounts. Vaccines with trace amounts of thimerosal contain 1 microgram or less of mercury per dose.The above, current statements from the US FDA, raise several concerns for me:
1) Theoretical potential for neurotoxicity of even low levels of organomercurials
2) continues to work with, vaccine manufacturers to reduce or eliminate thimerosal from vaccines.
Substantial decrease is not the same as total removal of mercury from vaccines. The California epidemiological study, at least, is not based on removal of mercury from vaccines.
3) Trace amounts
Why leave trace amounts in the vaccines to begin with? If trace amounts of thimerosal can still have a preservative effect on bacteria in the vaccines then why can't they also have a neurotoxic effect on children receiving the vaccines? And some of the flu vaccines, the ones not considered thimerosal free, contain more than trace amounts of thimerosal.
Their own statements appear to contradict their claims that the studies refuting a vaccine-autism link are based on periods when thimerosal was removed from vaccines.
