What this research studies

From 2022–2027, researchers will monitor people with new respiratory symptoms across Kaiser Permanente Washington and partner clinics to learn which viruses are causing illness and whether vaccinated people get sick less often. They will collect nasal swabs and test them for influenza, SARS-CoV-2, and other respiratory viruses, and compare illness rates by vaccination status and timing. The work includes outpatient visits and telehealth encounters to capture mild-to-moderate illness in the community. Results will be shared regularly to help guide vaccination practice and public health planning.

Who could benefit from this research

Good fit: Ideal candidates are adults and children in Washington state who seek care or testing for new respiratory symptoms at participating clinics or through telehealth.

Not a fit: People without recent respiratory symptoms, those outside the study area, or those unwilling to provide samples are unlikely to benefit directly.

Why it matters

Potential benefit: If successful, the project could show which vaccines and timing best reduce outpatient respiratory illness, helping improve vaccine recommendations.

How similar studies have performed: Similar US Flu VE Network efforts have previously provided useful real-world vaccine effectiveness data, although virus patterns and vaccines change each season.
