- Nationwide cohort study using SNDS compared high-dose (HD) versus standard-dose (SD) influenza vaccine effectiveness.
- HD influenza vaccine was associated with a significant reduction in influenza-related hospitalisations in French nursing homes.
- Relative vaccine effectiveness for influenza hospitalisations was 30.8% (95% CI: 11.8–45.7; P = .0029).
- Findings support preferential use of high-dose influenza vaccines in institutionalised older populations.
