Overall: High-Dose vs Standard-Dose Influenza Vaccines in Older Adults: A Meta-Analysis provides strong, precise, and directly applicable evidence that high-dose vaccination reduces hospitalization outcomes in older adults, though absolute benefits, adverse effects, and mortality improvement are not demonstrated.

Overall: This large contemporary meta-analysis supports meaningful reductions in hospitalization and death with nirmatrelvir-ritonavir among higher-risk outpatients, although reliance on observational studies and absent harm data limit certainty.

Overall: This small but well-conducted randomized trial found a large, durable reduction in recurrent cellulitis and hospitalization with a practical intervention, though its open-label single-center design and unreported harms limit certainty.

Overall: This large US observational study reports substantial RSV vaccine effectiveness against major clinical outcomes in nursing-home residents, but claims-based ascertainment, residual confounding, and absent absolute benefit and safety data temper confidence.

Overall: This well-conducted US observational analysis provides precise, clinically meaningful reassurance about the short-term safety and practical use of same-day COVID-19 and influenza vaccination, while residual confounding and absent absolute risks limit certainty.

Overall: This multicenter US observational study provides credible, clinically important evidence that both recommended RSV prevention strategies reduce infant emergency visits and hospitalizations, though residual confounding and absent absolute benefit and safety data limit certainty.

Overall: This large US observational study provides precise, clinically meaningful evidence of moderate protection from updated COVID-19 vaccines, but lacks absolute benefit and safety data and mainly supports existing practice.

Overall: This large US observational study links RSV prevention product introduction to substantially fewer infant hospitalizations and emergency visits in the second season, although residual confounding, absent absolute effects and safety data, and inability to distinguish the products limit its practice-changing strength.

Overall: Adjuvanted vs High-Dose Influenza Vaccines in Older US Adults: A Cluster Randomized Crossover Study — A highly relevant, very large pragmatic randomized study found no clinically meaningful effectiveness difference between two routinely recommended influenza vaccines, supporting flexible selection in older adults.

Overall: This large US observational study provides precise, clinically relevant evidence that RSVPreF3 vaccination is associated with fewer RSV hospitalizations, although residual confounding and the absence of absolute benefits and safety data limit its decisiveness.
