Autism and thimerosal-containing vaccines: Lack of consistent evidence for an association *

In 1999, concerns were raised that vaccines containing the preservative Thimerosal™ might increase the risk of autism and/or other neurodevelopmental disorders.


Between the mid-1980s through the late-1990s, we compared the prevalence/incidence of autism in California, Sweden, and Denmark with average exposures to Thimerosal-containing vaccines. Graphic ecologic analyses were used to examine population-based data from the United States (national immunization coverage surveys and counts of children diagnosed with autism-like disorders seeking special education services in California); Sweden (national inpatient data on autism cases, national vaccination coverage levels, and information on use of all vaccines and vaccine-specific amounts of Thimerosal); and Denmark (national registry of inpatient/outpatient-diagnosed autism cases, national vaccination coverage levels, and information on use of all vaccines and vaccine-specific amounts of Thimerosal).


In all three countries, the incidence and prevalence of autism-like disorders began to rise in the 1985–1989 period, and the rate of increase accelerated in the early 1990s. However, in contrast to the situation in the United States, where the average Thimerosal dose from vaccines increased throughout the 1990s, Thimerosal exposures from vaccines in both Sweden and Denmark—already low throughout the 1970s and 1980s—began to decrease in the late 1980s and were eliminated in the early 1990s.


The body of existing data, including the ecologic data presented herein, is not consistent with the hypothesis that increased exposure to Thimerosal-containing vaccines is responsible for the apparent increase in the rates of autism in young children being observed worldwide.

"The highly-touted New England Journal of Medicine Danish study failed to mention the very convenient fact that none of the Danish children had prior exposure to mercury, since Denmark, unlike the U.S. had, banned mercury from childhood vaccines in 1992, the year before the birth year of the children in the study.)"

but that's exactly what this paper is all about - they are looking at thre different countries with different thimerosal contents in their vaccines with essentially the *same* development of autism incidence over the past 15 years.

That's what I have been saying for ages - if autism is surging all over the world, but vaccine schedules AND vaccines used are completely different then it must be something else that is causing the rise in autism cases - this paper finally looks at the numbers in details



BTW that Rimland statement page is so full of gross generalizations that most of his statements are just plain wrong!
