Brief Summary

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

Better understanding of the immune responses to influenza vaccination is needed in order to understand situations of poor vaccine response. Adults will receive influenza vaccination and then have peripheral blood drawn at pre-defined intervals in order to study the lymphocyte responses.
