Brief Summary

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

This is a multi-center study designed to evaluate the safety and immunogenicity of a Fluzone revaccination in elderly adults aged ≥ 65 years.

Primary Objective:

To describe the safety profile for all subjects.

Secondary Objective:

To describe immunogenicity 28 days following revaccination with one of three Fluzone formulations.

Detailed Description

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

Subjects who previously participated in study FID29 will be invited to participate in this revaccination study. They will be assigned to 1 of 3 groups based on the group they were previously randomized to and the vaccine received in study FID29.

* Known or suspected congenital or acquired immunodeficiency, immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months, or long-term systemic corticosteroids therapy
* Chronic illness, at a stage that could interfere with trial conduct or completion, in the opinion of the investigator
* Current alcohol abuse or drug addiction that may interfere with the subject's ability to comply with trial procedures
* Receipt of blood or blood-derived products in the past 3 months, that might interfere with the assessment of immune response
* Receipt of any vaccination in the 4 weeks preceding the trial vaccination
* Planned receipt of any vaccine in the 4 weeks following the trial vaccination
* Known human immunodeficiency virus (HIV), hepatitis B (HBs) antigen, or Hepatitis C seropositivity.
