Description
Francisco Mourao and co-authors compare flu shot performance in a 2026 study from Portugal. Past studies often found shots worked better against mild illness seen in clinics than against severe illness in hospitals, but the studies used unlike designs. The new work applies the same method in both settings across nine seasons.
The team studied more than three thousand tested patients with flu-like illness. The shot cut mild cases by about forty percent and severe cases by a near match. The small gap between settings was not firm enough to count as real. Subgroup checks told the same story. Readers learn that current shots seem to help across care settings alike.
