Low Risk of Febrile Seizures From Vaccines


Many parents are concerned about the side effects of vaccines, including febrile seizures, on their baby.  A new study demonstrates that the risk of febrile seizures from vaccines is extremely low and is far outweighed by the benefits.

A febrile seizure is a seizure associated with a high body temperature. They most commonly occur in children between the ages of six months and five years, most frequently between 12 and 18 months old.  They occur in three or four out of every 100 children, and although they are frightening for parents, they rarely have any long-term effects.

Scientists from Vaccine Safety Datalink, a collaborative project between the Centers for Disease Control and Prevention and health care organizations, reviewed data on the frequency of febrile seizures between 2006 through 2011. The study found that vaccines can lead to febrile seizures at a rate of up to 30 per 100,000 children immunized. According to a commentary by the AAP that accompanies the study, this would translate into the low rate of approximately one additional febrile seizure per pediatric practice every five to 10 years. 

The American Academy of Pediatrics and authors of the report conclude that the benefits of the vaccines far outweigh the risks of febrile seizures. Withholding or delaying immunization could potentially lead to even more febrile seizures associated with the diseases, not to mention the disease itself.
