    This project was a protocol-based assessment. Evidence on the risk of febrile seizures (FS) after vaccination with inactivated vaccine (IIV) and 13-valent pneumococcal conjugate vaccine (PCV13) is mixed. Among children 6-23 months, we examined the risk of FS following IIV and PCV13 during the 2013-14 and 2014-15 influenza seasons, for which vaccine virus strains were the same.

    The Mini-Sentinel Operations Center posted this protocol for public comment from September 11, 2015 through September 25, 2015.  A revised version was approved for implementation by FDA on July 22, 2016. A log of changes is included in the revised protocol (v2).
