Mum’s flu jab not linked to autism

Getting the flu vaccine while pregnant does not increase the risk of the child developing an autism spectrum disorder, a large study has demonstrated.

The 10-year study of more than 196,000 children found no association between ASD and flu vaccination during the second and third trimesters of pregnancy.

Data showed an increased risk in the first trimester, but the authors say this was not statistically significant and likely to be a chance finding.

A flu infection during pregnancy was not a risk factor for ASD, the researchers found, but the mother’s age at birth was.
