Immune Senescence in the Elderly: Comparison of Immune Responses to Influenza Vaccine In Adults of Different Ages

The immune system is central to human health and its impairment can have serious consequences. One of the hallmarks of aging is the progressive loss of immune function exposing older people to increased risk from infectious diseases that would not normally be more than an inconvenience. This project will use state-of-the-art technology developed by the Stanford Human Immune Monitoring Center to survey older individuals for signs of immune system aging and to gather information about the factors associated with the decline of immune function.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.
