Study Summary
Cellular and humoral immune responses in individuals with active influenza infection will be assessed. Each year, up to 50 participants will be enrolled. The investigators hypothesize that influenza infection will elicit mostly memory immune responses rather than de novo immune responses to infection.
Primary Outcome
The investigators will compare neutralizing antibodies in sera, plasma, and nasal swab samples against the influenza strain that each participant is infected with as well as historical and recently circulating influenza virus strains. Antibody titers between different strains will be compared to understand if memory or de novo immune responses are generated following influenza infection based on inferred influenza exposure history.
