What this research studies

If you join, researchers will enroll outpatients who come in with respiratory symptoms during and outside the flu season and compare those who test positive for viruses to those who test negative using a test-negative design. You may be asked to provide a nasal swab and a small bloodspot sample, and to complete follow-up surveys. Selected virus samples will be genetically sequenced to track changing strains over time. The goal is to look at vaccine protection across age groups and over time since vaccination.

Who could benefit from this research

Good fit: Ideal candidates are people aged 6 months and older who seek outpatient care for acute respiratory illness at UPMC clinics or participating federally qualified health centers in the Pittsburgh area.

Not a fit: People who never seek outpatient care for respiratory symptoms, who are hospitalized, or who do not receive care at participating clinics are unlikely to be eligible or directly benefit from participation.

Why it matters

Potential benefit: Results could help doctors and public health officials refine vaccine recommendations and timing to better protect different age groups.

How similar studies have performed: Other network-based test-negative studies, including the US Flu VE Network, have successfully produced vaccine effectiveness estimates for influenza and COVID-19, so this is a well-established approach.
