Rotavirus Vaccination Is Associated With Reduced Seizure Hospitalization Risk Among Commercially Insured US Children.

Rotavirus commonly causes diarrhea but can also cause seizures. Analysis of insurance claims for 1773295 US children with 2950 recorded seizures found that, compared to rotavirus-unvaccinated children, seizure hospitalization risk was reduced by 24% (95% confidence interval [CI], 13%-33%) and 14% (95% CI, 0%-26%) among fully and partially rotavirus-vaccinated children, respectively.
