What this research studies

From a patient perspective, the team will work with Baylor Scott & White clinics in Central Texas to collect vaccination records and clinical information from people who come in with acute respiratory symptoms. Patients who seek outpatient care will be tested in the lab to confirm influenza, SARS-CoV-2, RSV, or other respiratory viruses. The researchers will compare infection and visit rates by vaccination status and by virus type to estimate how much vaccines reduce the chance of needing outpatient care. They will produce interim and annual estimates and monitor changes as viruses and vaccine recommendations change across seasons.

Who could benefit from this research

Good fit: Ideal candidates are people of vaccine-eligible ages who seek outpatient care for acute respiratory symptoms at Baylor Scott & White clinics in Central Texas.

Not a fit: People who live outside the Central Texas catchment area, those hospitalized for severe illness, or individuals who do not seek outpatient care are unlikely to be included or directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could help public health officials and clinicians choose and recommend vaccines that better protect people from outpatient respiratory illness.

How similar studies have performed: Similar vaccine effectiveness studies using outpatient test-confirmed cases have been used successfully in past flu and COVID-19 seasons to guide public health decisions, though ongoing surveillance is needed as viruses evolve.
