Febrile Seizures After 2010–2011 Trivalent Inactivated Influenza Vaccine
Validation of Febrile Seizures Identified in the Sentinel Post-Licensure Rapid Immunization Safety Monitoring Program
Description

Protocol-based assessment of the risk of febrile seizures following trivalent inactivated influenza vaccine administered during the 2010-11 influenza season among children ages 6 months through 59 months using a self-controlled risk interval design. Influenza vaccinations and febrile seizure cases were identified in electronic healthcare databases and underwent medical record review. The positive predictive value of three alternative febrile seizures definitions that use ICD9 data was evaluated. 

The information contained in this report is associated with an FDA Safety Communication issued on May 16, 2014. Click here to see the Safety Communication.

This protocol was posted for public comment from January 24, 2013 through February 7, 2013. A revised version was approved for implementation by FDA on April 26, 2013. A log of changes is included in the revised protocol (v2.0).
