Study: Vaccine doubles seizure risk in children

The combination MMR vaccine could raise the risk of fever-related seizures in children. That's the finding of a study in Pediatrics.

It suggests toddlers who receive the combination, measles, mumps, rubella and varicella vaccine are at higher risk of having a febrile seizure a week to 10 days after receiving the shot. That's compared to children who get the vaccines separately at the same visit.

Scientists say, although the combination shot doubles the risk of febrile seizure, the odds are still quite small.

Febrile seizures are brief convulsions brought on by fever that occur in about 5 percent of children between 6 months and 5 years of age.
