Early exposure to the combined measlesmumpsrubella vaccine and thimerosal-containing vaccines and risk of autism spectrum disorder
Abstract
Objective
This casecontrol study investigated the relationship between the risk of Autism Spectrum Disorder (ASD) onset, and early exposure to the combined MeaslesMumpsRubella (MMR) vaccine and thimerosal consumption measured from vaccinations in the highly genetically homogenous Japanese population.
Methods
Vaccination histories at 1, 3, 6, 12, 18, 24, and 36 months from birth were investigated in ASD cases (189 samples), and controls (224 samples) matching age and sex in each case. Crude odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated to determine relationship between MMR vaccination and ASD. The differences in mean values of the thimerosal dosage between cases and controls were analyzed using an unpaired t-test. MMR vaccination and thimerosal dosage were also investigated using a conditional multiple-regression model.
Results
There were no significant differences in MMR vaccination and thimerosal dosage between cases and controls at any age. Furthermore, the ORs (95% CIs) of MMR vaccination and thimerosal dosage associated with ASD in the conditional multiple regression model were, respectively, 0.875 (0.3452.222) and 1.205 (0.8621.683) at age 18 months, 0.724 (0.4211.243) and 1.343 (0.9971.808) at 24 months, and 1.040 (0.6481.668) and 0.844 (0.6321.128) at 36 months. Thus, there were no significant differences.
Conclusions
No convincing evidence was found in this study that MMR vaccination and increasing thimerosal dose were associated with an increased risk of ASD onset.

(11,641 posts)for most childhood vaccines:
Since 2001, with the exception of some influenza (flu) vaccines, thimerosal is not used as a preservative in routinely recommended childhood vaccines.
Thimerosal is a mercury-containing preservative used in some vaccines and other products since the 1930's. There is no convincing evidence of harm caused by the low doses of thimerosal in vaccines, except for minor reactions like redness and swelling at the injection site. However, in July 1999, the Public Health Service agencies, the American Academy of Pediatrics, and vaccine manufacturers agreed that thimerosal should be reduced or eliminated in vaccines as a precautionary measure...
