Study shows measles vaccine doesn't increase seizure risk in children

A new study shows that children between the ages of four to six are not at a greater risk of febrile seizures if they have taken the measles vaccine that includes protection against chickenpox.

The study, which was recently published in the journal Pediatrics, addressed concerns raised by a 2010 study that appeared in the same journal. The 2010 study reported the risk of febrile seizures to be twice as high in kids ages one to two who received the measles vaccine that included the chickenpox vaccine, according to the Chicago Tribune.

"The results provide reassuring evidence that neither MMRV nor MMR plus V appears to be associated with an increased risk of post-vaccination febrile seizures in this four-to-six age group," Dr. Nicola Klein, a co-director of the Kaiser Permanente Vaccine Study Center, said, the Chicago Tribune reports.

A febrile seizure is a brief, fever-related convulsion that is not considered dangerous, though it can be frightening. It does not lead to epilepsy or seizure-related disorders and is more commonly caused by a cold virus than a vaccine, the researchers said.

Regardless, in 2010, the U.S. Centers for Disease Control changed its recommendation to separate shots unless requested by a parent.

"Knowing what I know, if I had kids getting kindergarten shots, I would definitely have their vaccines bundled and spare them the extra injection," Klein said, according to the Chicago Tribune.
