A meta-analysis of
ten studies involving more than 1.2 million children reaffirms that vaccines don?t cause autism. If anything, immunization was associated with decreased risk that children would develop autism, a possibility that?s strongest with the measles-mumps-rubella vaccine.
Highlights
?
There was no relationship between vaccination and autism (OR: 0.99; 95% CI: 0.92 to 1.06).
?
There was no relationship between vaccination and ASD (autism spectrum disorder) (OR: 0.91; 95% CI: 0.68 to 1.20).
?
There was no relationship between [autism/ASD] and MMR (OR: 0.84; 95% CI: 0.70 to 1.01).
?
There was no relationship between [autism/ASD] and thimerosal (OR: 1.00; 95% CI: 0.77 to 1.31).
?
There was no relationship between [autism/ASD] and mercury (Hg) (OR: 1.00; 95% CI: 0.93 to 1.07).
?
Findings of this meta-analysis suggest that vaccinations are not associated with the development of autism or autism spectrum disorder.
