Influenza vaccination is associated with lower invasive mechanical ventilation and in-hospital death among French adults aged 65+ hospitalized with confirmed influenza, with aRRs of 0.88 and 0.90.
- Why it matters: Severe influenza outcomes remain common in older adults even with vaccine availability, and evidence on severity reduction in hospitalized patients is needed to guide vaccination efforts.
- What they did: Using France’s SNDS, the study analyzed 132,443 hospitalizations from October 2016 to December 2024 (excluding 2020–2021), balancing groups via entropy balancing and estimating adjusted risk ratios and multistate transition hazard ratios.
- The result: Vaccinated patients had fewer IMV events (2.9% vs 4.3%; aRR 0.88, 95%CI 0.83–0.93) and fewer in-hospital deaths (8.6% vs 8.3%; aRR 0.90, 95%CI 0.87–0.93), implying reduced severity and supporting vaccination in this population.
