First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study tested different doses of an influenza A H3N2 virus in 33 healthy adults aged 18 to 55. The goal was to find a dose that safely causes mild flu symptoms, so this virus strain can be used in future trials to test new vaccines or treatments. Participants were monitored for side effects and infection rates over 28 days.
