Brief Summary

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

The purpose of the study is to evaluate different doses of the Influenza A/H1N1 pandemic vaccine in adults and the elderly.

Primary Objectives:

* To describe the immunogenicity of the candidate vaccines after a single injection.
* To describe the safety of the candidate vaccines after a single injection.

Detailed Description

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

Participants will receive a single injection of their randomized vaccine on Day 0.
