Exploring how older adults perceived the impact of infectious diseases and vaccines on ageing: a cross-sectional study in France.
Article in BMC geriatrics, 2026. 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
backgroundThis cross-sectional study examined perceptions of health and ageing, and their influence on vaccine acceptance among individuals aged 65 and older living at home in the Auvergne-Rhône-Alpes region of France.
methodsAnonymous online questionnaires were distributed to users of CARSAT Rhône-Alpes (N1 = 50,000) and Auvergne (N2 = 9,597). The 62-question survey covered vaccination perceptions, the impact of the Covid-19 pandemic, health concerns, preventive measures, health information sources, and vaccination history. Vaccine hesitancy was assessed using the 5 C model, categorizing respondents into the group ‘Opposed’, ‘Hesitant’, and ‘Very Favourable’ to vaccination based on vaccination history and reasons for non-vaccination.
resultsOut of 3,331 respondents, 2,416 questionnaires were analysable. Most participants identified stroke (43.4%), cancer (20.4%), and dementia (18%) as primary health concerns. Infectious diseases ranked lowest, with pneumonia (1.24%), Covid-19 (0.89%), influenza (0.43%), and shingles (0.11%) infrequently cited. The Hesitant group more frequently questioned vaccination recommendations (82%) compared to the Very Favourable group (74%). Opposed participants significantly doubted vaccine efficacy and its role in healthy aging, differing from Hesitant and Very Favourable participants (p < 0.001). Perceptions of vulnerability to infection and beliefs about the seriousness of vaccine-preventable diseases significantly differed among groups (p < 0.001), with higher agreement in the Very Favourable group. Health-preservation behaviours, like regular medical check-ups and vaccination, were more common among the Very Favourable group, with no correlation found between diet, physical activity, and vaccination status.
conclusionsThe worry of infectious diseases is low compared to fear of disability. Differences in perceptions of infection vulnerability and vaccine efficacy highlight the need for targeted communication to enhance vaccine acceptance.
