From Seasonal Strategy to Pandemic Shield: The Case for Prioritizing Influenza Vaccination in Long-Term Care.
Article in Vaccines, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe COVID-19 pandemic exposed both the fragility and importance of long-term care facilities (LTCFs). In this context, seasonal influenza vaccination is more than a routine intervention, it is a measurable indicator of system readiness.
methodsWe conducted a secondary analysis of the validated 2022 WHO-UNICEF Joint Reporting Form (JRF) on Immunization for all 194 Member States, extracting (i) policy inclusion of older adults and LTCF residents/staff and (ii) availability of numeric coverage data. Findings were interpreted alongside evidence on vaccine effectiveness and delivery in LTCFs as proxies for operational preparedness.
resultsOf 194 countries, 128 (66%) reported a national influenza-vaccination policy. Among these, 109 (56%) recommended vaccination for older adults, while only 84 (43%) explicitly included LTCF residents (few countries explicitly named staff). Numeric coverage for older adults was reported by 54 countries (median 55%, range 0-103%), with 13 meeting the WHO ≥75% target. No country reported specific coverage for LTCF residents or staff. Evidence from trials and observational studies shows that vaccination reduces hospitalisation and mortality among residents and that higher staff uptake is associated with fewer resident infections and improved continuity of operations. Facilities achieving high joint coverage appear to reflect stronger governance, supply chains, data systems, and infection-prevention capacity, the same elements required for pandemic response.
conclusionInfluenza vaccination in LTCFs functions as both a barometer and a mechanism of preparedness. Three practical levers should be recognised as core readiness functions: explicit inclusion of LTCF residents and staff in national policy; routine, public reporting of resident and staff coverage; and timely, resourced on-site delivery before seasonal peaks. Embedding these features would better protect those at highest risk and strengthen overall health-system resilience.
