Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a retrospective cohort study of children included in a large medical insurance claims database.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* To evaluate the rate of FluMist administration compared to other influenza vaccine use in the following pediatric populations:

* Children younger than 24 months of age
* Children 24-59 months of age with a claim associated with a diagnosis of asthma
* Children 24-59 months of age without a claim associated with a diagnosis of asthma, but with dispensed medication for wheezing
* Children 24-59 months of age with immunosuppression
* To describe, in children in the above populations who receive FluMist, the type and number of Emergency Room visits or hospitalizations associated with an insurance claim within 42 days of receiving FluMist
* To explore the rationale for FluMist immunization of pediatric populations that are excluded from recommended usage by characterizing the use in these populations
