Influenza Vaccination Coverage in Children with Neurologic Disorders and Their Siblings, July 2006-June 2014.

Children with neurologic disorders are at high risk for influenza-associated complications. We identified 184,460 children 1-17 years of age with neurologic disorders and 204,966 siblings in a commercial insurance claims database from July 2006 to June 2014. Among children with neurologic disorders, coverage increased from 22.4% in 2006-2007 to 42.3% in 2013-2014, but remained suboptimal. A lower proportion of siblings were vaccinated.
