Following this puts new work involving it at the top of your briefing, with a note saying why it is there. Links are taken from the source record, never inferred.
Retrospective cohort study of 4,257 hospitalized older adults showing vaccination associated with 26% relative risk reduction in in-hospital death (95% CI: 3–43%) but minimal effect on ICU admission; reinforces established benefit against severe mortality outcomes.
A single-centre cross-sectional survey with self-reported vaccination status and no clinical outcomes; findings describe a gap but cannot establish causation or guide clinical practice changes.
Single-center retrospective audit of vaccination coverage in a regional CF cohort; documents suboptimal uptake for influenza and COVID-19 but lacks comparative design, causal analysis, or intervention testing to support practice change.
Phase 1/2 trial demonstrating that AS03-adjuvanted H5N8 vaccine met FDA immunogenicity criteria with acceptable safety in adults, but lacks efficacy data and comparative effectiveness evidence needed for practice-changing claims.
